Class 1: RenderMan, RIB, RSL..

RenderMan, RIB

RSL

AOVs

Variety of names: arbitrary output vars, auxiliary buffers, multiple buffers, secondary buffers..

Rasterize once, shade multiple times. HUGE savings in render times.

Here is a sample RIB file which renders an extra buffer.

REYES vs Rays

Ray tracing was added to REYES in 2002 - starting with PRMan 11..

The idea is to support hybrid/mixed rendering (selective ray tracing).

Performance [tuning]

There are several ways to ensure efficient rendering:

---

1. ---

2. ---

3. ---

4. ---

5. AOVs

   ---

6. 
   

   ---

7. true 3D vs sprites

   ---

8. ---

9. shadow maps - tight bounds

   ---

10. helpers (external RIB generators), eg. see Malcolm's page.

11. shader DSOs
