WebVectors are multiplied by matrices following a precise set of rules in order to modify the values of the vector in a particular way. GLSL has native support for two, three and four dimensional matrices: mat2 (2x2), mat3 (3x3) and mat4 (4x4). GLSL also supports matrix multiplication (*) and a matrix specific function (matrixCompMult()). WebApr 5, 2024 · Matrices in GLSL. In GLSL there are special data types for representing matrices up to 4 \times 4 4×4 and vectors with up to 4 4 components. For example, the mat2x4 (with any modifier) data type is used to represent a 4 \times 2 4×2 matrix with vec2 representing a 2 2 component row/column vector. round beni ourain cushion
