Method ApplyToVector3Array

math32/matrix3.go:121–135

ApplyToVector3Array multiplies length vectors in the array starting at offset by this matrix. Returns pointer to the updated array. This matrix is unchanged.

(array []float32, offset int, length int)

// Returns pointer to the updated array.
// This matrix is unchanged.
func (m *Matrix3) ApplyToVector3Array(array []float32, offset int, length int) []float32 {

	var v1 Vector3
	j := offset
	for i := 0; i < length; i += 3 {
		v1.X = array[j]
		v1.Y = array[j+1]
		v1.Z = array[j+2]
		v1.ApplyMatrix3(m)
		array[j] = v1.X
		array[j+1] = v1.Y
		array[j+2] = v1.Z
	}
	return array
}

// Multiply multiply this matrix by the other matrix
// Returns pointer to this updated matrix.
