Fixed function pipeline opengl es
4 Answers. you might like this tutorial: Recreating OpenGL's Fixed Function Pipeline using Cg. It is in CG, but that is rather similar to GLSL, with a few tweaks, one could surely turn it into a shader that would mimic fixed-function pipeline on Android. As for the other deprecated functions, such as glVertex*(). \$\begingroup\$ The fixed-function pipeline has been deprecated in both OpenGL and DirectX, so I wouldn't waste your time with it. Basic shaders are pretty straightforward, and certainly no more complicated than understanding enough to get a rendering context working. \$\endgroup\$ – . OpenGL ES 2/3 and WebGL require a valid program containing a vertex shader and a fragment shader; there is no fixed-function pipeline.
Excuse, that I can not participate now in discussion - there is no free time. But I will return - I will necessarily write that I think on this question.
Very valuable message
