What They Say
Imagination Technology has developed a system to classify ray tracing performance to help developers understand how ray tracing can be supported, at appropriate levels of efficiency (e.g. for mobile apps).
- Level 0 – Legacy Solutions
- Level 1 – Software on Traditional GPUs
- Level 2 – Ray/Box and Ray/Tri Testers in Hardware
- Level 3 – Bounding Volume Hierarchy (BVH) Processing in Hardware
- Level 4 – BVH Processing with Coherency Sorting in Hardware
- Level 5 – Coherent BVH Processing with Scene Hierarchy Generator in Hardware
What We Think
Imagination has been working on ray tracing for a long time, but unlike Nvidia, which has in the past tended to ‘throw hardware at the problem ‘, Imagination has been focused more on low power graphics. Of course, this may change when Nvidia has taken control of ARM. (BR)
