Real-time Gray-scale Scene Rendering in MultiGen-Vega Applications

摘要：

MultiGen-Vega is a software environment widely used in real-time VR (Virtual Reality) 3D visual simulation. For some particular applications,rendering gray-scale scene is necessary but Vega itself does not provide it. Based on the structure of Vega program,Vegas channel callback function system and OpenGL,two methods were presented to realize it. They are based on texture mapping. Method 1 uses the fixed texture mapping functionality in OpenGL;Method 2 uses GLSL (OpenGL Shading Language) to create a fragment shader to replace the fixed functionality;and both of them satisfy the real-time requirement. Whats more,Method 2 takes use of the great graphics ability and programmability of modern GPU;it provides an additional flexibility and can be used to realize other effects that are not provided by Vega. These two methods also can be applied to other scene management system based on OpenGL.
