From: http://clootie.narod.ru/delphi/download_custom.html 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).
