i heard that there maybe an implentation of reyes archeticture…what ever that is!
im guessing it is to do with rendering, and viewports etc. so would this speed up the calculations of light on channel layers (i.e. blue, green, red, nor, depth) and on opengl or shaded views of meshes. if so maybe some coders could implement a realtime rendering/ lighting solution that big production houses use for testing final shots on the fly. basically it is a render split into channels, red, green, blue, depth (Z), nor, alpha…possibly shadow?!..these layers combine with a simple shaded scene/ model allow them to change the lighting in realtime but effect the render (which is at 80-90%) final render qaulity. check the pixar papers out for more on this.
anyway this would (imo) be an awesome tool for blender, for example if you let it interface with renderman or using the internal renderer (once it supports some more features) and you have a nice render but there is one or two lighting conditions you dont like you go and edit it in render and have it like you want and then go re-render on full settings…anyway just an idea.
