Category: PowerVR Ray Tracing


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

There are many phrases and concepts that have entered our subconscious via pop culture. One of my all-time favorites has to be the idea of knowns and unknowns commonly used inside NASA to outline the degree of uncertainty in safety-critical missions. Known unknowns result from phenomena which are recognized, but poorly understood. On the other hand, unknown unknowns are phenomena … Continued

Mobile World Congress in Barcelona has served as a launchpad for some of the most exciting innovations in graphics technologies from Imagination. In 2014 we disclosed the in-depth architectural details for the PowerVR GX6650 GPU and the way we’ve designed its 192 ALU cores while 2015 saw the introduction of PowerVR GT7900, a super-GPU aimed at game consoles and laptops. … Continued

Graphics on mobile devices have seen an incredible evolution in the last decade. Imagination revolutionized the handheld industry in 2001 by launching a family of PowerVR GPUs designed for the very first wave of smartphones. Since then, we’ve set the standard for ultimate performance and energy efficiency with every release of the PowerVR graphics architecture. About two years ago, a … Continued

In an article published earlier this week, I described how developers can implement fast, ray traced soft shadows in a game engine running on our PowerVR Wizard architecture. Today I’d like to present some very exciting results which demonstrate how ray tracing delivers significant reductions in memory bandwidth and power consumption over traditional rasterized methods (i.e. cascaded shadow maps). Complete … Continued
