hoa_video::private_video::ParticleVertex Class Reference

this is used in the vertex array for DrawArrays(). Every time the particle system is rendered, we need to iterate through all the particles in the system, and use the position, size, and rotation to generate 4 ParticleVertex's. This is pretty expensive, but unfortunately it's necessary since the positions change every frame. More...
