Vertex Arrays, VBO's and Point Sprites with C/C++ in openFrameworks 006
A while ago I'd posted an example and source code for using Vertex Arrays, Vertex Buffer Objects and Point Sprites in openFrameworks. This was for openFrameworks 005 and needed some mods to the core and other hacks to get it to do what we needed. In the current version of openframeworks (006+) a lot of the required functionality has been moved to the core and so we don't need the extra classes MSAImage and MSATexture, or to hack the core. The updated example is attached and can be downloaded from below.
P.S. An example on particle system with OpenCL for even more performance (updating the particles on the GPU) can be found here.
