While ray tracing can produce much more realistic imagery than rasterization, it is also

computationally intensive. We have found that the best approach is hybrid rendering, a

combination of ray tracing and rasterization. With this approach, rasterization is used where it is

most effective, and ray tracing is used where it provides the most visual benefit vs rasterization,

such as rendering reflections, refractions, and shadows. Figure 16 Shows the hybrid rendering

pipeline.

Hybrid Rendering combines ray tracing and rasterization techniques in the rendering pipeline to

take advantage of what each does best to render a scene. SEED uses a hybrid rendering model for

their PICA PICA real-time ray tracing experiment that features self-learning agents in a

procedurally-assembled world. Built using SEED's R&D engine Halcyon, PICA PICA implements

real-time ray tracing using Microsoft DXR and NVIDIA GPUs.
