The big topic at the Game Developers Conference this year is Ray-Tracing. Yesterday we covered how Microsoft is now introducing DirectX Raytracing, or GDC, and today, AMD along with GPUOpen are showing off what they have in store. AMD is announcing Radeon ProRender support for real-time ray-tracing in conjunction with its open-source Radeon Rays, which is part of the GPUOpen initiative. Nice to see AMD is continuing the push of open-source technologies for graphics. While I still have my doubts on if this will be a reality in the near future, it is nice to see that it is finally moving forward after all these years. AMD is announcing Radeon ProRender support for real-time GPU acceleration of ray tracing techniques mixed with traditional rasterization based rendering. This new process fuses the speed of rasterization with the physically-based realism that users of Radeon ProRender expect for their workflows. At a high level, the process achieves these results by using rasterization to draw basic structures and surfaces before a ray tracing process is used to compute advanced light-effects like reflections, shadows and transparency. The flexibility of the process allows users to decide when these advanced light effects are actually necessary and add noticeable new dimensions of realism to their renders.
