What's New in PowerVR SDK v3.1

PowerVR SDK v3.1

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

• Stopped disabling inactive effects in material view. Their name is now simply displayed in red.
• Fixed bug in which a warning would repeatedly pop-up if a POD file had invalid materials.
• Fixed bug saving to read-only files.

• 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.

Utilities

• PVRGeoPOD v2.12
• Collada2POD now falls under the PVRGeoPOD name. CL and GUI binaries can be found in the PVRGeoPOD Standalone folder.
• Added Max and Maya 2013 support.
• Added Blender 2.63 support.
• The POD specification is now accessibly from the Help menu.
• Added support for %POD to the Post Export command-line arguments. That string will get replaced with the POD filename upon execution.
• Added UI option to choose the mapping channel used when generating tangent-space data.
• The fixed point option has been removed. Vertex data can be exported as fixed point but transformations, material, colours, etc. cannot.
• The option in 3D Studio Max to export the bones as geometry has been removed.
• The PVRGeoPOD UI has been redesigned and now uses Qt.
• PVRGeoPOD now supports profiles allowing you to save your export configurations.
• Modified the way the interleaved data is aligned. Now each vertex attribute will get aligned to a 32-bit boundary instead of each vertex.
• 3DSMax: Fixed the export of a scene supplied by a developer that had a skinned character where a couple of vertices weren't correct.
• Maya: The bump map texture is now correct.
• Blender: Fixed the decomposition of the transformation matrix in certain cases where an object has been mirrored.

GLSL ES Compilers v1.9

• Renamed folder from PVRUniSCo to Compilers and renamed compilers themselves to glslcompiler_xxx.
• Updated the offline GLSL compilers for SGX535, SGX540 and SGX543 with latest versions.
• Added offline GLSL compiler for G6x00

PVRShaderEditor v2.0

• Renamed PVRUniSCoEditor to PVRShaderEditor.
• Completely overhauled PVRShaderEditor which now uses Qt GUI framework across all platforms.
• A number of stability fixes on Unix systems when the compiler is invoked.
• Compilers are now built-in to application.
• Added G6x00 compiler.
• Improved shader edit panel with cursor matching.
• Improved search highlighting.
• Fixed bug BRN36872 (crashing on compile on OSX). This was due strange 64bit PVRTString formatting issues.

PVRShaman v2.0

• PVRShaman's GUI interface has been converted to Qt to provide a much better look and feel across all platforms.
• Added support for OpenGL ES 3.0
• Added the ability to define ‘user semantics’ which allow the creation of arbitrary semantics of types supported by the rendering API.
• Removed generic unneeded items under an effect within the container tree panel.
• Added the display of semantics under an effect within the container tree panel. Hovering over these items displays the data they contain.
• Added a number of new semantics including cos(time), cos(time)*2PI, etc.
• Added a new dialog which allows editing of user-defined semantics.
• Fixed SimplePostProcess.pfx as it had mipmapping enabled for a texture with no mipmaps.
• Fixed crash in container panel were textures may have been accessed if they didn't exist.
• Fixed bug in which only post process passes were setting their render-to-texture as written. Changed so all passes set render-to-texture flag to written if they have a render-to-texture. This means data in container panel is more visible.
• PFX format description is now accessible from the help menu.
• Removed throw of exception if POD options cannot be loaded. Just uses defaults and outputs a warning.
• Added arrow keys to allow navigating in FPS mode.

PVRTexTool v4.0

• Added 3DSMax and Maya 2013 plug-ins
• Added Windows Explorer plug-in to preview PVR files in the file browser
• Added more robust KTX file support, including support for OpenGL ES 3.0 formats
• Added more robust DDS file support, including support for DirectX10 style headers

• Modified ETC behaviour so that NPOT textures can now be encoded
• Removed ETCMedium and ETCMediumPerceptual from the ETC compression options
• Modified "Bleed" behaviour to be more aggressive

Command Line

• Added new interface. Old interface still works, but will output deprecation warning. See manual, or -help for new usage. Most common arguments remain largely the same, with the exception of the style and specific parameter values
• 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
• Fixed power-of-two check for PVRTC and ETC
• 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
• Added support for more recent DirectX11 and OpenGL ES 3.0 formats. DirectX11 support includes filtering down to 9.3 and 10.1 feature sets
• 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

Library

• Moved header files from PVRTexLib folder to a sub-folder "Include"
• Fixed crash when trying to encode to DXT/BC when textures have dimensions that are not multiples of 4
• Changed line "#elif _WINDLL_IMPORT" to "#elif defined(_WINDLL_IMPORT)" to avoid preprocessor problems

• Added auto-update support
• Tool windows are now moveable docking windows
• Fixed “broadcasting servers” GUI element when multiple PVRTune’s are running (or if a new PVRTune was launched before the old one had exited)
• 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
• Counter table has a new column that can be enabled: "selected". This shows the average counter values over the currently selected range
• The 'z' key is now a shortcut to view the selected range, or "all" if there is no selection
