![]() Each representing a matrix of 2x2, 3x3, and 4x4 dimensions, respectively. ![]() Matrix types are data types designed to handle Matrix operations. The components of a vector can be accessed by using the “.” notation and specifying the x, y, z or a component of the vector.įor example: //Declaring and defining a vec4 vectorįloat alphaValue=light.a Matrix Data Types Each representing a vector with 2, 3 and 4 components, respectively. Vector types are data types designed to handle Vector operations. Each representing the value of an integer, a floating point or a boolean, respectevely. Scalar types include int, float and bool. The following discussion applies only to OpenGL ES 2.0 GLSL Data Types What makes it different from any other language is that it contains data types especifically designed to handle 3D mathematics. It can handle loops and conditional statements like for-loops, while-loops and if-else statements. As any other programming language, GLSL contains data types such as int, float, bool. It is based on the “C” programming language. The OpenGL Shading Language (GLSL) is a programming language designed for OpenGL shaders.
