WebArray of scalars or vectors: Each element has a base alignment equal to that of a vec4. Matrices: Stored as a large array of column vectors, where each of those vectors has a base alignment of vec4. Struct: Equal to the computed size of its elements according to the previous rules, but padded to a multiple of the size of a vec4. WebIf I Know GLSL, 5 What Do I Need to Do Differently to Write a Compute Shader? Not much: 1. A Compute Shader is created just like any other GLSL shader, except that its type is GL_COMPUTE_SHADER (duh…). You compile it and link it just like any other GLSL shader program. 2. A Compute Shader must be in a shader program all by itself. There
