WebMar 28, 2016 · GLSL allows for three basic types of data: bool: Boolean values; true or false; int: integer values; whole numbers in a certain range, -n..n; float: floating point values; numbers with a fractional component; GLSL facilitates the manipulation of vectors and matrices. A vector or matrix is always composed of values of the same basic data type. WebMar 16, 2014 · Each index essentially takes a vec4, so if you pass a vec3 in [x, y, z], it's going to get padded internally to [x, y, z, 0]. Same with passing a float, it would be padded to [x, 0, 0, 0]. A mat4, on the other hand, takes up 4 * vec4 of space, thus it'll take up 4 indices.
