Today (ahem), some references to shaders, which can really bring life to your Quest3D application.

First off, some examples:

The infamous NVIDIA shader library
Some shaders that could be converted to Quest3D
Some shaders from the so-called vvvv toolkit

Most of these can be converted to Quest3D quite easily, if you know the semantics.

Some tutorials to help you get started:

Facewound : Basics on post-processing, I do have the feeling I posted this before somewhere…. don’t hit me if I did.
Direct3D basics : Basics on shaders, very, very basic.

Inspirational:
Punkuser : some guy got variance shadow maps working on omni-lights… which is awesome.

I can also highly recommend ShaderFX, it natively supports Quest3D for crying out loud. Although you are limited to creating materials (no post-processing stuff) and the nodes they provide. Unless you create your own custom nodes of course.
