Detailed Description

Particle-system based on OpenGL point-sprites.

This particle system is very fast but it has deficiencies. Left unimplemented was a mechanism to update particles. MediumParticleSystem has a crude way to adjust size of point sprites by distance (but it's imperfect and hardware limits point size).

Texture is specified by stateset. Example: new MediumParticleSystem( MediumParticleSystem::Args( Texture::NewTextureAsStateSet( "smoke.png" ) ) );
