Hi. Does anyone know what rendering technique(s) (e.g radiosity, ray-tracing, etc) Poser uses in its image renderer? Thanks. ks

Oh hell...I used to know this. Sreed? I think that's what it's called. I can't really remember.

Close Scott - Sree3D, created by an amazing fellow, Sree Kotay. But that's just the realtime display. I think that Poser 4's renderer is based on a Phong render (sure looks like one).Poser 5 is a hybrid Surface Subdivsion/Ray Tracer. Best -Dan

Sree3D is the realtime preview, correct. The P4 renderer is Larry's work, from what I can see a "standard" scanline Phong renderer. No radiosity, no ray-tracing. The Poser 5 renderer is a node-based REYES-renderer that can use ray tracing for certain features like reflections. Where Phong renderer are interpolating polygons normals when shading a pixel, REYES renderers divide polygons in micropolygons that are smaller than a pixel.

Oh yes. Poser 4's startup shows various names including Sreekant Kotay. Poser 3's startup screen showed names infl;uding Mowgli Windos!!! (Rudyard Kipling's character working for Microsoft??? :-) )

Sree is a genius. Never met him in person, but just reading his code blows my mind.

Where have you seen his code?

If you look closely at the Poser 5 splash screen you will notice my name in it...plus I worked with the Viewpoint SDK before that.
