Description

This example shows how OpenCL can bind to existing OpenGL buffers to avoid copying data back off a compute device when using the results for rendering. This is demonstrated by displacing the vertices of an OpenGL managed vertex buffer object (VBO) using a compute kernel which calculates several octaves of procedural noise to push the resulting vertex positions outwards and calculate new normal directions using finite differences.
