106 | 106 | I think the best approach is to extend graphics/!ShaderProgram.cpp to support GLSL shaders (it was designed with that in mind, but I don't know if it'll actually work without some interface changes); then move all the renderer's existing fixed-function texture-environment setup code into ShaderProgramFFP.cpp and implement GLSL-based equivalents, so that most of the rest of the renderer code doesn't have to care whether it's using FFP or GLSL (it just uses the CShaderProgram interface). Also, change all immediate-mode drawing (glVertex3f etc) to vertex arrays. I think that should deal with the most serious problems, and the code would all be shared between GLES and desktop GL modes (no need for forking or #ifdefs etc) and can be tested with desktop GL. Then there's probably just lots of little issues remaining, which can be addressed as they occur. |
