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 ...

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.

Here mat is "passed by reference", trans is passed by value. It's a lie. "inout" function parameter qualifier will result in two "deep copies" of your data.

WebOct 20, 2024 · In GLSL, like Direct3D 9, the texture binding is part of the sampler state. In GLSL, you present much of the OpenGL state as pre-defined global variables. For example, with GLSL, you use the gl_Position variable to specify vertex position and the gl_FragColor variable to specify fragment color. In HLSL, you pass Direct3D state explicitly from ...
