360° VR panorama videos have been trending on YouTube since the viewing feature was introduced in 2015. Even without a VR headset they offer a uniquely immersive experience. What I’m referring to are mostly live action movies shot with a growing list of 360° video capable cameras. These panoramas are actually two 360×180 equirectangular 2D images stitched together and projected … Continued

The title of this post uses the word ‘revelation’ instead of ‘revolution’ because mobile game engines are only inching their way toward using full-on ray tracing. The mobile game community wants ray tracing but the roadblock has been the lack of hardware fast enough to keep up with the challenging frame rates. This is where Imagination’s optimised for mobile, PowerVR … Continued

In our previous article, we explained the basics of the PowerVR ray tracing API, including the scene generation and ray handling. In this article, we will show how to put those rays to good use to render different effects and compare the results with their rasterised counterpart. The video below is Ray Factory, our latest hybrid rendering demo:   Better rendering with … Continued

2017 is going to be a really exciting year and we’ve put together a list of predictions. Many of the technologies we’ve been discussing for years are about to hit the mainstream. Gartner calls this the ‘Slope of Enlightenment’, where the true benefits of a technology become clearer and more widely understood (note that Gartner wasn’t involved in the formation … Continued

To render images at interactive framerates, engines have to approximate the behavior of real world phenomena – such as shadows – rather than simulating them. As real time rendering techniques continue to push towards photorealism, the cost of these approximations approaches the point of diminishing returns. Although traditionally seen as a complex offline process, ray tracing is becoming an increasingly … Continued

In this blog post I will give a quick overview of the API created by our PowerVR Ray Tracing team. This API gives developers access to the PowerVR Ray Tracing hardware known as the Wizard architecture. I will briefly go over the physical changes at the hardware level and what has changed compared to a traditional GPU. Then I will … Continued
