ABSTRACT

In this paper, the design method of OpenGL graphics processing module is analyzed, and a graphics processing method based on DSP + FPGA structure is proposed. And design a can realize the function interface standard of OpenGL graphics processing module, from the OpenGL based modeling, coordinate transformation, fire hidden technology, light illumination model and texture mapping are introduced the principle of OpenGL and 3D GIS modeling method and the three-dimensional modeling technique were to explore and research.

Keywords:

3D modeling, DSP, FPGA, GIS, OpenGL.
