Realtime Toon shader ?

Joao Sapiro

Hello again ! i was wondering if anyone has an .fx of a toon shader or any pertinent information on how to create an aproximate effect , right now i was gonna tackle it by using an inverted model with a bit of push with black material and inverted normals , and self ilum set to 100. But thats the most i can do in realtime. 3ds max

thanks in advance !

tons of .fx shader samples ship with directx sdk and are also available with nvidia stuff http://developer.download.nvidia.com/shaderlibrary/webpages/shader_library.html

the most common way is to use a 1D ramp texture for lighting, you access it via the dot product (Normal.VertexToLight). and additionally you would do sort of a "black" rim light to get conturs (Normal.CameraToVertex)

Your best bet is probablly that sweet uber shader that was posted for max/maya a while back, i think it had the ability to load custom ramp textures? I remember seeing some people doing some toon shader type stuff.
