WebDescription. C = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array. Web16 apr. 2024 · Data Types. In GLSL, the types vec2, vec3, and vec4 represent 2D, 3D, and 4D floating-point vectors. (There are also types for integer and boolean vectors, which are not discussed here.)
