Method ApplyMatrix3

math32/vector3.go:453–462

ApplyMatrix3 multiplies the specified 3x3 matrix by this vector. Returns the pointer to this updated vector.

(m *Matrix3)

// ApplyMatrix3 multiplies the specified 3x3 matrix by this vector.
// Returns the pointer to this updated vector.
func (v *Vector3) ApplyMatrix3(m *Matrix3) *Vector3 {

	x := v.X
	y := v.Y
	z := v.Z
	v.X = m[0]*x + m[3]*y + m[6]*z
	v.Y = m[1]*x + m[4]*y + m[7]*z
	v.Z = m[2]*x + m[5]*y + m[8]*z
	return v
}

// ApplyMatrix4 multiplies the specified 4x4 matrix by this vector.
// Returns the pointer to this updated vector.
