Spiral cloud/galaxy rendering using opengl / glsl

Описание

A small part of one of my projects in real-time graphics course at DTU. It shows how multi-texturing and blending using shaders in OpenGL can be used to create cool effects like these, a fast spinning "spiral galaxy" and a beam. It's not pre-rendered, it runs in real-time on an opengl rendering engine i'm working on. Also, since all the geometry needed are 3 quads (not including the skybox), it has a very low impact on frame rate.

The engine is a C++/Python hybrid using Boost::Python, more info: http://www2.imm.dtu.dk/visiondag/VD08/posters/pdf/Visionday08-3Dmusic.pdf
