WebGL Shaders: Your Direct Line to the GPU
WebGL shaders are small programs written in GLSL that run directly on the GPU, bypassing the CPU for massively parallel graphics tasks. They are essential for all WebGL rendering, positioning vertices and coloring pixels.
Think of WebGL shaders as your direct line to the GPU. They are small programs, written in a C-like language called GLSL, that execute in parallel for every vertex or pixel in your scene. A vertex shader calculates a vertex's final position, while a fragment shader determines a pixel's final color. A common footgun is forgetting that shaders must be compiled and linked into a `WebGLProgram` before use; a compilation failure in your GLSL code will halt rendering entirely.
