Opengl fixed function lighting
Web17 de jul. de 2009 · I’m asking this with OpenGL 3.1 in mind, so the fact the fixed-function hardware performs those computations in eye space is not important. All right, a serious response now (so shoot me). Your world space may have coords large enough lighting in that space would result in precision probs in the GPU. Also, to light in world, you have to … WebOpenGL Lighting By default, OpenGL's fixed-function pipeline implements the Blinn-Phong Shading Model. – Originally from Bui Tuong Phong's Ph.D work at the University of Utah (1973). – Modified by James F. Blinn (1977). Light is modeled in three categories: ambient, diffuse, and specular.
