Abstract:

Improving the speed of threedimensional scene has always been a major challenge which programmers need to face. With the appearance and popularization of the multicore processor, using the cores on processor instead multithreading methods to improve parallelism of the program has become a possibility. This article introduces the development of virtual reality tools OpenGL and parallel programming interface OpenMP which is a sharedmemory systems, analyzes the general process of using OpenGL to draw up the threedimensional scene, and takes the texturemapping as an example to discuss how to used OpenMP in the OpenGL program to enhance the parallelism.

Key words: virtual reality, multicore, OpenGL, OpenMP, parallelization
