Cyrille and me made [gemvertexbuffer] object while we were trying something with OpenCL.
This object fillin a VBO (Vertex Buffer Object) with pd tables values.
It looks like scopeXYZ but we think it's more flexible.
It's very fast (100000 points @ 250 fps on a Nvidia Geforce 9400M).
We know that something similar already exists in the vertex folder of Gem but we need to do it by ourself to better understand VBO workflow.
As we learned a lot of things doing this, we hope that it could help someone else, so we share it...

It has been test on Ubuntu.
If you want to build it, you just need to adjust paths in the Makefile and run make.

Cheers

Antoine
