Method ProjectOnVector

math32/vector3.go:545–551

ProjectOnVector sets this vector to its projection on other vector. Returns the pointer to this updated vector.

(other *Vector3)

// ProjectOnVector sets this vector to its projection on other vector.
// Returns the pointer to this updated vector.
func (v *Vector3) ProjectOnVector(other *Vector3) *Vector3 {

	var on Vector3
	on.Copy(other).Normalize()
	dot := v.Dot(&on)
	return v.Copy(&on).MultiplyScalar(dot)
}

// ProjectOnPlane sets this vector to its projection on the plane
// specified by its normal vector.
