http://www.lighthouse3d.com/tutorials/glsl-tutorial/texture-coordinates/ WebNewer GPUs can handle setting different parts of gl_FragColor, but older ones can't, which means they need to use a temporary to build the final color and set it with a 3rd move instruction. You can use a MAD instruction to set all the fields at once: const vec2 constantList = vec2(1.0, 0.0); gl_FragColor = mycolor.xyzw * constantList.xxxy ...

It's possible to share code by using glAttachShader to combine shaders, but this doesn't make it possible to share things like struct declarations or #define-d constants.It does work for sharing functions. Some people like to use the array of strings passed to glShaderSource as a way to … WebGLSL has very flexible notation for referring to the components of a vector. One way to access them is with array notation. For example, if v is a four-component vector, then its components can be accessed as v [0], v [1], v [2], and v [3]. But they can also be accessed using the dot notation as v.x, v.y, v.z, and v.w.
