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.

Translating OpeGLES fixed function pipeline to programmable pipeline on the fly. You would probably need two textures, one for the indices, and one for the palette, with two levels of sampling in the fragment shader. ES supports logical operations (glLogicOp) as part of the per-fragment operations that are executed after the fragment shader.
