Abstract
We have designed an algorithm which allows the OpenGL geometry transformations to be processed on a multiprocessor system. We have integrated it in Mesa, a 3D graphics library with an API which is very similar to that of OpenGL.We get speedup up to 1.8 for biprocessor without any modification of the application using the library. In this paper we study the issues of our algorithm and how we solve them.
