Using Vertex Buffer Objects to transfer my mesh data (vertices, normals, curvatures) directly into GPU memory using STATIC_DRAW_ARB pointers just tripled the performance of my GLSL shader implementation. Running a heavy model (+300k vertices) drawn with contours and suggestive contours at 24 fps, average.

The current plan for my thesis is to compare several implementations I made, which all have the same purpose: draw contours and suggestive contours on a given mesh, as fast as possible, as correct as possible. It’s time to review the status of the current builds of these different tools. …
