[Bf-committers] Qdune and the render API

[David Bryant]

  I've observed all the conversation over this issue and really the answer is basic.Any Renderman compliant renderer or micropolygon renderer is "always" going to be slower than it's basic counterparts.Why? It simply has more work to do.

Pixar's Renderman,Turtle.Maxwell ,and all other commercial renderers selling point is not their speed but the quality of their renders.If you're looking for it to compete with straight raytracers.The common renderer is going to win hands down every time.If Qdune can render an awesome render in a "reasonable" timeframe,you've reached your goal.If you optimized the code to get even a 10% speedup you've done even better.

Every feature Blender has up to this point has started from version 1.0 as it were.All the features in Blender has been strengthened over time.

The ultimate question should be can it do what it's supposed to do "now".What you would like it to do will come later as you improve on it. 

Mental Ray is in it's fourth revision,Turtle is in it's third, Renderman is in it's 12th or 13th and so on.Don't judge heavy duty renderers soley on their render speed.Production quality customizable renderers are not as fast as you might think.
So utimately the base decision is do you want to still work on it and go from 1.0 to 2.0 to 3.0 and so on.
