ParticleSystem1 - unidirectional generator sample
Main idea of this sample was to demonstrate right and wrong ways of generating uniform distribution of unit length vectors - so end-points formed by these vectors forms sphere surface. But in process of providing visual feedback for user some other interesting techniques appeared.
I try to list them below (in advanced - beginner order):
Vertex shader assembler code for particle systems with particle size calculation.
Stencil buffer / matrix operations for mirror rendering.
Various frame buffer blending modes.
Rendering graphs with with transformed and lit vertices.
Usage of DrawPrimitiveUP D3DDevice method (for graph rendering).
