What's New in PowerVR SDK v3.3


PowerVR SDK v3.3

Overview

  • The PowerVR Graphics SDK v3.3 includes support for the recently ratified OpenGL ES 3.1 in PVRVFrame, our desktop emulation libraries.
  • PVRTrace now includes full recording capabilities on Android 4.4 (KiKat) and the handling of Android Native Buffers has been improved. Developers also now benefit from enhanced search and remote recording capabilities and complete support for OpenGL ES 3.0 API.
  • PVRTune implements a new ‘monitor’ window which provides a simplified and high-level overview of CPU, memory and graphics loading, allowing developers to quickly isolate application bottlenecks. It also has improved highlight and selection capabilities and implements new per-PID stats.
  • In addition, the SDK’s documentation has been comprehensively reviewed and updated.

Note

Full support for the recently ratified OpenGL ES 3.1 API has been added to PVRVFrame. Please note that this support is only intended for early development, as an OpenGL ES 3.1 conformance test has not yet been released. To use it, please download the header files from the Khronos website. We will shortly release a full SDK highlighting the most important features of this new API.

Examples

  • ToneMapping: Now it uses point sampling for its float texture.
  • OcclusionQueries: Fixed the name of the texture variable in the effect.pfxs.
  • ShadowMapping: Fixed a typo in the OGLES3 effect.pfx file which resulted in the texture coordinates being uninitialised.
  • EdgeDetection: Moved initialisation of timer to InitView so the first value is valid. This fixes the problem using -fft command-line option.
  • MagicLantern: Moved initialisation of timer to InitView so the first value is valid. This fixes the problem using -fft command-line option.
  • Water: Updated with new assets including a new skybox, ship and terrain.
  • Shaders: Improved command-line parsing so it doesn't attempt to match any option that begins with -s or -m.
  • DeferredShading: Stencil buffer was not requested in the EGLConfig for ES3, but was assumed and used. Now updated to always request a stencil buffer.
  • TextureStreaming: New example for Android and iOS.
  • Added OGLES3 iOS project files for all examples capable of running on iOS.

PVRTools

  • PVRTString: Added positional variants of the format commands.
  • PVRTTexture: Added PVRTC sRGB texture support.
  • PVRTPFXParser: Fixed crash while processing texture wrap parameters.
  • PVRTArray: Changed the Sort() method to use merge sort instead of bubble sort.
  • PVRTError: Fixed warning in PVRTError.h as the format parameter to printf was not a string literal.
  • PVRTResourceFile: Added a null pointer check in GetFile.
  • Added a new CameraInterface library for Android and iOS which allows quick initialisation and usage of hardware cameras to stream textures to OpenGLES.

PVRShell

  • Improved the Android OS lifecycle.
  • Modified PVRShellOutputDebug on Windows to dynamically allocate its buffer instead of using a fixed size of 1024

PVRShaman v2.3

  • Fixed bug in which the Save POD icon would be greyed out.
  • Added the displaying of POD textures such as bump and specular level to the Material Properties dialog.
  • Fixed bug when using external shader files in a PFX material. The material would fail to pass validation.

PVRTexTool v4.1.3

Library

  • Fixed issue with BC1 Compression producing holes in fully opaque textures when an entire block was the same colour.
  • Fixed memory leak in ETC2 Codec.
  • Integrated latest version of PVRTC codec, which should produce generally better quality images, and manages threads a bit more smartly.
  • Fixed issue with certain ETC textures not compressing correctly under Windows.

GUI

  • Font texture generation now outputs white textures rather than black.
  • Fixed channel swapping so that when multiple file sources are selected, it correctly copies the channels.
  • Fixed memory leak when zooming in/out of Diff window.
  • Added RGBA/RGB distinction for PVRTCv1.
  • Added PVRTC sRGB support.
  • "Single" display mode now zooms to/from the mouse position, rather than the corner of the screen.

PVRVFrame v9.8

  • Added OpenGL ES 3.1 support.
  • Fixed vertex_array_object extension not being emulated on OSX.
  • Fixed GLSL translator where reserved identifiers were erroneously added to the GLSL source.
  • Fixed EGL_SUCCESS not being reported by some EGL functions in cases where it should.
  • EGL_BAD_ALLOC now reported by eglCreateWindowSurface on Windows platforms if the application attempts to re-use an HWND for which the pixel format has already been set.
  • Fixed EGL context ids where it would not always be unique.
  • Fixed GL_LUMINANCE texture data clamping to [0,1].
  • Fixed glBindRenderbuffer where it would not work with names not generated by glGenRenderbuffer.
  • Fixed a crash in glDeleteSamplers.

PVRTune v14.73

  • PVRScope library only: Reduced noise in per-core activity counters.
  • PVRScopeStats.h, PVRScopeReadCountersThenSetGroup(): Updated comment to consider standalone performance-tracking applications such as PVRMonitor or a logging app.
  • PVRPerfServer can now send CPU usage info for 'interesting' PIDs that it sees: apps that connect via PVRScope, PIDs shown in HWPerf timing data, and PIDs specified on the command line. To enable it, specify "-pid" on the command line. To additionally watch specific PIDs, specify "-pid=A,B" etc.
  • Added per-core task time counters.
  • Added per-PID stats: TA Busy %, 3D Busy %, 2D Busy %, Compute Busy %, 3D SPM %.
  • Dynamic counters created per PID or CID now place the PID/CID number first; gives easier sorting.
  • CPU usage can now be sent per core and per PID.
  • Memory usage can now be sent for the system and per PID. Added counters: Memory use, Memory total, Memory load, PID %u: Memory use.
  • Added new docking window: Monitor. This gives a simplified 'at a glance' view of the CPU, memory and graphics loading.
  • Fixed: When connecting, disconnecting and reconnecting, pause was enabled by default.
  • Search window
    • The "select" tick box has been removed.
    • Mouse-over search results now highlights the relevant time range (if any) in the graph views.
    • Single-click on a result now pans the view, rather than panning + zooming.
    • Double-click on a result now pans and zooms the view.
    • Holding the Ctrl key while doing either of the above also selects the time range. (Similar to how Ctrl+click in a graph view is used to alter the selected time range).
    • Hold Ctrl+Shift to extend the existing selection.
    • Added View\Find - Ctrl+F now works to bring up Search (shows, raises and sets focus to the input box).
  • Graph Views
    • Now display the highlighted time range.
    • Ensure selection/highlight range draws are always at least 1 pixel wide.
    • If there is a task under the mouse, highlight the entire time range.
    • Ctrl must be held to modify the selection - don't suddenly allow Shift by itself to extend the selection.
    • Ctrl+clicking on a task now sets the selection to be the entire task time-range - giving 'snap' behaviour. Additionally, hold Shift to instead extend the existing selection.
  • Counter Table
    • Added a new counter table column: Highlight.
    • Counter Table default columns are now: 1s, Selected, View.
  • Counters
    • Enable SPM counter in Developer build.
    • Renamed some US counters to USC.
    • Increase the maximum graph y-axis value that may be entered.

PVRShaderEditor v2.3

  • Performing a search when the ASM Output widget has focus now searches the ASM widget instead of the main editor.
  • Deleting or moving a file which is currently open in PVRShaderEditor will now correctly prompt whether to discard the file or keep the file in the editor.
  • Fixed bug in which re-opening the editor when closed with a blank file and the option 'Save Session' selected would display an IOError.
  • Fixed bug which meant that PFX line cycle counts and errors were only being displayed for the entire GLSL block, rather than per-line, if the GLSL code is embedded.

PVRGeoPOD v2.16

  • Fixed the exporting of .h/.cpp files from Maya and Max.

PVRTrace v3.3

GUI

  • Fixed the saving of the wireframe colour to the preferences.
  • The call summary now allows the addition of highlights to the calls in the call viewer, as well as to find all occurrences of that call using the search feature.
  • The call summary now supports multiple selection of calls using Ctrl+left mouse click and Shift+left mouse click.
  • It is now possible to search calls within a specific frame range and by thread.
  • Status bar messages no longer timeout.
  • The minimum number of characters that can now be searched for is 1.
  • Search results can now be selected with Enter when navigating with arrow keys.
  • Tidied up/simplified the Remote Controller interface.
  • The default for the number of search results has been raised from 100 to 500

  • Added support for recording on Android 4.4, KitKat.
  • Added support for recording eglImages created from EGL_NATIVE_BUFFER_ANDROID client buffers.
  • Supports JSON-formatted configuration files.
  • It is no longer needed to specify the Android drivers to use when recording in the config file as the recording libraries will locate them as long as they are located in /system/lib/egl or /vendior/lib/egl.
  • Fixed a failure to open the recording file on Android if %pname is used and the process name has slashes in.
  • Renamed some command-line options: --windowsToUse becomes --window, --delayRenderFrame becomes --delay and --iterations becomes --repeat.
  • Fixed multidraw support.
  • Added missing ES3.0 functionality.

Documentation

  • Extensions: Added GL_EXT_shader_framebuffer_fetch and added EXT_separate_shader_objects.
  • Fixed an error in the User Guide where it incorrectly stated the FSAA command for the PVRShell as "-FSAAMode=N" instead of the new "-aasamples=N".

PowerVR SDK v3.2

Builds

  • Added Linux build flag V1BUILD that allows you to link OGLES applications with libGLESv1_CM and libEGL instead of libGLES_CM.

Examples

  • Added OGLES2 OcclusionQueries example.
  • Added OGLES2 MultipleRenderTarget example. This example uses the GL_EXT_draw_buffers extension.
  • Added OGLES2 Glass, a dynamic dual-paraboloid environment mapping example.
  • Added OGLES3 ColourGrading which demonstrates performing colour grading using a 3d texture as a look up table.
  • Added OGLES2 MultiThreading example demonstrating the correct technique of loading GL resources on a separate thread.
  • OGLES3CubeShadowMapping: Removed some redundant uniforms.
  • PVRScopeRemote: no longer reports success/fail messages using PVRShellOutputDebug() - it now remembers the result and displays a message using Print3D: "PVRScopeComms failed - is PVRPerfServer connected?"
  • PVRScopeRemote now uses the new PVRScope function pplSendProcessing() to have a custom timeline in PVRTune, which marks the time period of RenderScene(). As these tasks have a frame number, PVRTune is able to group them with TA and 3D tasks.
  • OGLES2/OGLES3 Fractal: Simplified so it no longer creates its unneeded depth attachment. The attachment was originally put in to teach developers how to create a depth attachment but now the RenderToTexture example demonstrates this.
  • OCL_OGLES2ImageConvolution: Modified to use CL_KHR_egl_image extension if available.
  • OGLES1 AntialiasedLines: Removed this outdated demo.
  • iOS OGLES/OGLES2 HelloAPI: Fixed examples as they previously rendered a black screen.
  • RenderToTexture: Added EXT_multisampled_render_to_texture.
  • OGLES2 Water: Fixed a shader precision issue in SkyboxVShader.vsh that was causing minor flickering on some hardware.
  • OGLES2 Water: Updated the example to calculate the FBO dimensions based on the width and height as opposed to being hardcoded at 256.
  • Removed the Cygwin dependency on Windows of the Android SDK by fixing the Android.mk files of all the Android examples and Android Tools.
  • Updated iOS project templates. Renamed to *.xcodeproj; updated project compatability version to 3.2; removed support for armv6; enabled Thumb support (as we now only compile for armv7+); fixed some incorrect and deprecated settings; increased the minimum target version to 4.3.

PVRTools

  • Added EXT_occlusion_queries_boolean #defines to CPVRTgles2Ext class.
  • Added GL_EXT_draw_buffers extension functionality to CPVRTgles2Ext extension class.

  • PVRTglExt: Updated extension class to use new 3.2 functionality for querying extensions.
  • PVRTTextureAPI: Removed deprecated Luminance/Alpha formats.
  • PVRTShader: Modified behaviour so that #define values will now be correctly inserted after a #version marker.
  • PVRTString: Updated the format function to use _vscprintf when on windows for getting the size of the needed string.
  • Added pre-processor commands to PFX. It is now possible to specify a block of pre-processor #defines in an [EFFECT] block which will be prepended to a given GLSL shader.
  • Updated iOS OGLES and OGLES2 Tools projects to remove support for armv6; removed some unnecessary settings; enabled Thumb support (as we now only compile for armv7+); enabled compile of Prefix.pch which sets some iOS specific #defines and fixes some issues as TARGET_OS_IPHONE was being incorrectly manually set in the project settings.
  • Added GL_EXT_multisampled_render_to_texture to the CPVRTgles2Ext extension class.
  • Fixed bug in PVRTUnicode which would incorrectly test for overlong values in the PVRTUnicodeValidUTF8() function.
  • PVRTPFXParser.cpp: Fixed loading external files invoked a 'new', where it should invoke a 'malloc'.

PVRShell

  • Added support for the command-line to the Android shell. This can be used by doing: am start -a android.intent.action.MAIN -n com.powervr.OGLESIntroducingPOD/.OGLESIntroducingPOD --es args "-info"
  • Wired up PVRShellGet(prefEGLSurface) in the KEGL/PVRShellAPI.cpp
  • Fixed a bug which would cause a crash in PVRShell if the EGL extension string is null.

PVRShaman v2.2

  • Fixed bug incorrectly parsing #version tag for ES 3.0 shaders.
  • Disabled 'Save Shader' action if there's no modification to the shader or the underlying file is read-only.

PVRTexTool v4.1.1

  • GUI: Fixed displayed blend diff percentages - previously the percentages were the wrong way around.
  • GUI: Fixed rendering math that sometimes caused channels to be rendered with a small (1 luminance) error before appearing on screen.
  • GUI: Modified DirectX format list so that DXGI_FORMAT_B5G5R5A1_UNORM, DXGI_FORMAT_B4G4R4A4_UNORM and DXGI_FORMAT_B5G6R5_UNORM are now represented in the correct TexLib order - which means they are now listed as "ARGB 1 5 5 5", "ARGB 4 4 4 4" and "RGB 5 6 5" respectively.
  • Modified DXGI mappings to match actual order of data in DirectX for DXGI_FORMAT_B5G5R5A1_UNORM, DXGI_FORMAT_B4G4R4A4_UNORM and DXGI_FORMAT_B5G6R5_UNORM.
  • GUI: Added option to remove anti-aliasing from generated fonts.
  • GUI: "Change Grid Size..." and "Change Background Colour..." dialogues now correctly display the PVRTexTool icon in the top corner.
  • GUI: When creating a texture array, if no textures are selected, an error dialogue now appears.
  • GUI: When creating a texture cube map, if no textures are selected, a more specific error dialogue now appears.
  • GUI: The title of the dialogue that pops up when you select "Change Background Colour..." from the view menu, now correctly displays "Change Background Colour..." as its title.
  • GUI: Selecting quality of PVRTC Compression is now possible when being warned about rectangular textures.
  • GUI: Warning is now mentioned when compressing a non-power of two ETC1 texture.
  • GUI: Modified "diff" value in display dock so that it now gets the absolute difference between the input and output textures, rather than the pixel value of the image displayed in the middle, which may not match up.
  • GUI: When exiting and a texture is modified, the user may now cancel the closing process by either hitting "cancel" on the save question, or cancelling the save itself.
  • GUI: Added functionality to load custom surfaces via the surface browser.
  • GUI: Fixed issues with GUI burning CPU time whilst idle.
  • CLI: Modified the help passage for "Flip", so it's a little easier to understand.
  • CLI, GUI: Added TGA support.
  • CLI: Fixed -square option so that it correctly rounds up when using the "+" modifier.
  • CLI: Removed legacy command line options.
  • Lib: Width/Height/Depth queries now correctly check against the MIP map count when returning the size of a given MIP map level.
  • Maya: Fixed bug with Plug-In causing it to not work at all.
  • Maya: Added 2014 Support.
  • 3DSMax: Added 2014 Support.
  • Modified BC Codec to correctly compress punch through BC1 textures.
  • Updated linear and cubic interpolation methods to higher quality, lower error rate resizing methods.
  • Resize operations all now use a stepped resize, regardless of interpolation mode. This means that the image is reduced/expanded by two over and over until it hits the correct size. This results in a slower operation for resizes with a greater change in size, but with a significantly higher quality output.
  • Added even faster, lower quality mode of compression for PVRTC.
  • Added canvas resize to list of preprocessor options, allowing padding to be added to an image.
  • Fixed ETC1 Compression when padding to block sizes, as was incorrectly accessing invalid data. NPOT textures should now compress as intended.

  • 9.6 Fixed a bug in glEnable and glDisable where enums weren't being validated correctly.
  • 9.6 Fixed a bug where the result of querying GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS wasn't being clamped to a maximum of 32.
  • 9.6 Added a workaround for an NVIDIA/Linux GL driver bug where glIsBuffer is unreliable.
  • 9.6 Emulator: Improved hardware profile management. Profiles are now read at runtime from the file selected in the GUI, and new profiles may be added.

PVRTune v14.49

  • v14.46 PVRTune and PVRPerfServer now show the Series and the Variant of the PowerVR graphics hardware.
  • v14.46 Search results are now highlighted in the Timing data.
  • v14.45 Renamed/split PVRScope.h into PVRScopeComms.h and PVRScopeStats.h. This change is to improve documentation.
  • v14.41 * The time period (in ms) between CPU Load samples can now be specified on the PVRPerfServer command line (-c=N) or remotely, from the PVRTune GUI.
  • v14.41 * The View menu now has an option to change the graph background.
  • v14.41 * Group-changed Marks in the graph view now show the new group number, where possible.
  • v14.40 New tool window: Search.
  • v14.40 Fix BRN43811: PVRPerfServer will later crash if the error "AppLib server 2 initialisation failed" appears
  • v14.38 It is now possible to close graph panes; there is a close button in the top-right corner.
  • v14.37 PVRScope has two new API's: pplSendProcessingBegin() and pplSendProcessingEnd(). These allow an application (or thread, or context) to mark out named and numbered regions of processing.
  • v14.37 Example app PVRScopeRemote has been updated to use these APIs.
  • v14.37 PVRTune:
  • v14.37 * Performance improvements, particularly on multi-core CPUs.
  • v14.37 * Now renders marks under the timing data - this prevents the timing data from being completely obscured by a glut of marks.
  • v14.37 * Always show manual marks over all time-lines. (In red as before.)
  • v14.37 * Marks from PVRScope connections are now shown in purple, only over that connection's timeline.
  • v14.37 * Custom time-lines are marked with the string passed into pplInitialise, or if there isn't one then the application name.
  • v14.37 PVRScope to PVRPerfServer communications (non-Android): stability fixes.
  • v14.34 Applications that use PVRScope can now have a custom time-line to mark out ranges of processing. This sends a time-stamped begin/end marker to PVRTune. Every begin must be followed by an end; they cannot be interleaved or nested. PVRTune will show these as an activity timeline.
  • v14.34 * PVRScope: added pplSendProcessing().
  • v14.34 * Applications can set a 'frame number' on these tasks. For 3D applications, this means that the CPU load of processing a frame can be matched to the GPU load, giving a greater view of the full frame time.
  • v14.34 * The order of the time-lines: user then cores. This puts the app data below the GPU data, so for example PVRScopeExample activities go CPU, TA, 3D from bottom to top.
  • v14.34 * If a PVRScope-enabled app is sending Marks and a custom time-line, only draw Marks over that timeline.
  • v14.34 * This can also be used as instrumented debugging, for example visualising the behaviour of multi-threaded apps.
  • v14.34 Graphs can now be stacking in the y-direction. Graph drop and drop has been updated to respond to the mouse cursor.
  • v14.34 * Graph view no longer has the TA/3D and Pause buttons - these are now only in the context menu (or the keyboard shortcut). This is because these settings are per graph, and there can now be more than one graph in the view.
  • v14.34 The initial PVRTune view once connected now defaults to a layout showing the most basic information. This initial view has three graphs, stacked vertically.
  • v14.34 * The top graph shows the % load on the fundamental cores: CPU, 3D, TA, etc.
  • v14.34 * The second graph shows the FPS.
  • v14.34 * The third graph shows the timing data and marks.
  • v14.33 PVRTune now has an SPM counter, showing percentage of 3D tasks which are for SPM.
  • v14.33 Drag and drop of multiple files now works; the first file is loaded.
  • v14.33 PVRTune now shows some details of broadcasting servers, in the status bar of the connect window.
  • v14.33 Fixed a rare bug which could prevent the graph UIs being created.
  • v14.33 Now redraw the entire graph when a new time-line appears.
  • v14.33 Ctrl+I now brings up the PVRPerfServer info window.
  • v14.33 PVRScope library only: fixed frame number counting for Rogue.
  • v14.33 PVRScope library API now allows the app to keep up with HWPerf data even if counters are calculated less frequently. PVRScopeExample app is updated to take advantage for its "interval" function.
  • v14.33 PVRPerfServer now has three extra methods to query the CPU count. This should improve the CPU load graph on some multi-core CPU devices running Android.

Compilers

  • Changed filename of compilers to 'ProfilingCompilers' and updated filenames. Removed SGX535 compiler.
  • Updated Windows, Linux and OSX offline compilers to 1.9@2650911

  • Added ability to open multiple files with a selection from the Open File dialog.
  • The Save menu command now enables/disables to reflect the status of the document.
  • Read-only files are now more visible as the document tab title displays this attribute. Save commands are disabled when a file is marked as read-only.
  • Fixed external shader files referenced within a PFX which were not handled/loaded correctly.

 

PVRGeoPOD v2.15

  • Added Max and Maya 2014 support.
  • 3DSMax: PVRGeoPOD is now capable of exporting textures assigned to Normal Bump maps.
  • 3DSMax: Fixed the exporting of UVs when vertex colours and vertex alpha are applied to a mesh.
  • Blender: Fixed the exporting of meshes that are in Edit Mode.
  • Blender: Fixed lock-up on exit of Blender on OSX.
  • Blender: Added experimental support for dupli groups.
  • Where appropriate the specular level is now incorporated into the specular colour.

  • Fixed renaming of configurations that had been loaded from the "registry".
  • Removed the feature where options would be loaded from a POD file if you were overwriting it.
  • As well as the directory re-structure the command-line version of PVRGeoPOD now uses the abbreviation CLI.

PVRTrace v3.2

  • PVRTraceGUI: Added static analysis which is performed upon opening a trace file. Static analysis checks for common mistakes which can cause rendering defects or performance issues. This new functionality is encapsulated inside a new Static Analysis widget.
  • PVRTraceGUI: Added an 'overdraw' statistic to the Shader Analysis element. This details the average overdraw for the current analysed frame.
  • PVRTraceGUI: Added vertex shader complexity graphing to the newly renamed 'Shader Analysis' tab. This was formely named 'Pixel Analysis'.
  • PVRTraceGUI: Fixed the Discard override for GLSL ES 300 shaders.
  • PVRTraceGUI: Added new statistics graph dialog which graphs various values across the entire length of the trace. This allows for quick navigation and visualisation of peak loads.
  • The PVRTrace recording libraries now append the PVRTrace version to the GL_RENDERER and EGL_VERSION strings.

 

PVRHub v1.0

Release 1, Update 1

PVRShaman v2.1.2

  • Added 64bit support. This fixes a crash on start-up on systems running OSX 10.7 Lion and OSX 10.6 Snow Leopard.

Release 1

Builds

  • Rebranded the SDK icons.
  • Updated GLES headers.
  • The builds folder has been restructured. The various headers can now be located in Builds/Include and libraries can be located in //Lib. As part of this rearrangement the Linux common and platform makefile includes have been modified. They now handle dependencies better and have made it easier to build examples for multiple APIs if the need arises.
  • Removed the inclusion of --rpath=/usr/lib from the HelloAPI Linux makefiles as it was causing problems tracing when on some platforms.
  • Removed references to the splash screen from the BlackBerry 10 projects.
  • Updated the global SDK location variable for BlackBerry10 from IMG_SDK_HOME to PVRSDKDIR.

Examples

  • Updated demos with new logo.
  • Fixed the file wrapping of shaders and effects in the Visual Studio projects so they are wrapped as strings instead of binaries.
  • Fixed the wrapping of POD files in the OGLES3 Visual Studio projects for x64 builds.
  • Added ldpi, mdpi and xhdpi Android icons.
  • Removed the API from the menu name of the applications in Android and iOS. The API is now contained in the icon.
  • Enhanced usage of DiscardFramebufferEXT/InvalidateFramebuffer in examples that use Frame Buffer Objects.
  • Removed erroneous calls to TestEGLError from the HelloAPI examples.
  • BinaryShader : Fixed the shader path allocation.
  • Shaders: Updated OGLES2/3 to use new PVRTextureHeader.
  • The iOS projects no longer list the .pvr source pngs.

PVRTools

  • Added drop shadow to Print3D fonts.
  • Fixed rounding issue for Print3D layout when font is scaled.
  • Updated Print3D to use different shaders for the font and logo.
  • Updated the logo used by Print3D to the new branding.
  • OGLES Print3D now unbinds the texture at the end of the flush.
  • Changed the default texturing filtering method to bilinear filtering.
  • Added PVRTCII support to texture loading code for OpenGL ES 2 and 3.
  • PVRTMatrixQuaternionMultiplyF now uses a temporary variable for calculating the multiplied quaternion. This fixes a problem where the destination quaternion is also used as an input quaternion.
  • The OGL extension loading code now first attempts to load GL_ARB_framebuffer_object and if that isn't present falls back to GL_EXT_framebuffer_object.
  • Added fix to PVRTC decompression to force access to PVRTCWords via individual members, which caused an issue with the Android gcc compiler.
  • Updated OpenGL/ES texture loading codes to correctly handle loading from a specified MIP Map level.
  • Modified how PVRTBackground.cpp is destroyed, as previously allowing Graphics API release mechanisms could crash the app if the API context was destroyed prior to the background class being destroyed.
  • The OGL extension loading code now loads GL_ARB_framebuffer_object instead of GL_EXT_framebuffer_object.
  • PFXParser: Fixed an issue in which some GLES implementations require square brackets in the call to glGetUniformLocation if the uniform name in the shader is an array.
  • The OGLES2 Print3D now resets the program and the bound 2D texture.

PVRShell

  • The Android shell will now display any set exit message as a “toast” on exit.
  • Fixed an infinite loop that can occur in the Android shell if the application returns false from InitApplication.
  • The GLX part of the PVRShell now sets up GLX_SAMPLE_BUFFERS and GLX_SAMPLES if the option -aasamples isn't set to 0.
  • FSAMode has been replaced with prefAASamples and -aasamples. Now when you want to use aa you define the number of samples you wish to use.
  • Removed OpenVG setup code.
  • OpenGLES: Shell now automatically discards depth and stencil data from main framebuffer after a render. Options to turn these discards and discarding colour on/off have been added. Discarding for framebuffer objects still needs to be performed manually.
  • EGL: Added EGL extensions to the '-info' output of PVRShell

All Utilities

  • Fixed problem on Linux KDE that impeded opening the applications when the splash screen was activated.

PVRShaman v2.1

  • Renamed "Current" option in channel editor to "Current Texture" to be clearer.
  • Renamed "Swap Channels" button in channel editor to "Apply Changes", as original wording was unclear.
  • Added padding to BCn texture compression, allowing NPOT and non-block-sized textures to compress successfully.
  • Fixed offset when using linear and cubic resize methods, so that lower right pixels are no longer near-duplicates of their neighbours, and data isn't shifted slightly to the upper left.
  • Fixed occasional crash in pixel lookup when switching between MIP Map levels.

Command-line

  • Filetype checking is no longer case sensitive, uppercase file extensions are now correctly parsed.
  • Flip argument with "flag" parameter now works correctly as expected.
  • Default output name now inserts ".Out" if the auto-generated output name matches the input filename.
  • Fixed Legacy PVR file io for cubemaps and texture arrays

Installer 3.0.2

  • The Linux Installer will now create .desktop entries in the /usr/share/applications folder for each utility that is installed.
  • The Linux Installer will now copy icons PNGs into /usr/share/icons/hicolor.

  • TGA and GIF are no longer supported
  • Side-by-side compression and decompression is now available via the new interface

Command Line (Deprecated Interface)

  • Fixed issue causing encoding failure when loading from texture files

  • Inconsistent behaviour with the "border" option - the option now consistently ADDS a border, rather than maintaining the original size, which was different from the GUI, the Library and previous incarnations of PVRTexToolCL
  • Border option was not adding the correct width to PVRTC 2bpp textures, instead always adding a 4x4 border. Now an 8x4 border size is correctly used when compressing to PVRTC2
  • Fixed bleed filter - previously the flag did nothing, and warning was always output

GUI

  • Added a small pop-up informing the user that the utility is still doing something when encoding a texture
  • Pre-Processing dialogs no longer exist, instead a toolbox with equivalent functionality is now provided
  • Added icons to the quick bar for diffing

  • Removed legacy OpenVG and DirectX9 formats
  • Due to now large number of supported formats per-API, a new encoding dialog has been created with the ability to filter formats based on user requirements
  • Encoding a texture now results in a new texture window being created which can be worked on in the same way as the original. Diffing is available as more generic functionality between any two texture windows, as long as the textures match in size. User can specify automatic generation of a diff window when encoding
  • Comparing two textures now has more options, with the traditional colour diff available alongside a new tolerance diff, and a blend of the two textures
  • TGA and GIF are no longer supported

  • PVRTune for Mac OS X now builds Universal
  • Added pplSendFlush() to PVRScope
  • Some implementations cache data sends. If the data rate is low, the real send of data can be significantly delayed. If this behaviour causes an issue, call this function to force a cache flush
  • If it is necessary to use this function, the best results are likely to be achieved by calling with a frequency between once per second up to once per frame. If data is sent extremely infrequently, this function could be called once at the end of each bout of data send
  • The user can now select a range. Holding the CTRL key changes click+drag from "move view" to "select range". SHIFT+click grows the selected range. Selected range is drawn transparent and with a ruler
