Function mulV3

mulV3(m: Mat4, a: Vec3, b: Vec3): Vec3
b = m * a

Multiplies the 4x4 matrix m by the 3-element column vector a and stores the result in the 3-element vector b.

This is a convenience function where m is assumed to be a 3D transformation matrix and a implicitly represents the homogeneous coordinates [ a.x, a.y, a.z, 1.0 ]
Parameters
- m: Mat4
  the 4x4 matrix multiplication operand
- a: Vec3
  the 3-element vector multiplication operand
- b: Vec3
  a 3-element vector in which to store the result
Returns Vec3
b as the result of m * a
