Getting Ready
We're going to implement three functions: one to retrieve the translation already stored inside a 4 X 4 matrix, one to return a translation matrix given x, y, and z components, and one to return a translation matrix given the same x, y, and z components packed inside a vec3. When building any type of matrix, we start with the identity matrix and modify ...
