GLKVector4

Overview

The GLKVector4 type defines a 4-component floating-point vector as well as many mathematical operations commonly used to manipulate vectors. Graphics programming uses vectors extensively to represent positions, normals, colors and other data structures.

The functions that manipulate GLKVector4 structures treat the inputs as immutable, instead returning a new vector that represent the results of the operation.
