Method GetNormalMatrix

math32/matrix3.go:282–288

GetNormalMatrix set this matrix to the matrix to transform the normal vectors from the src matrix to transform the vertices. If the src matrix cannot be inverted returns error.

(src *Matrix4)

// from the src matrix to transform the vertices.
// If the src matrix cannot be inverted returns error.
func (m *Matrix3) GetNormalMatrix(src *Matrix4) error {

	m.SetFromMatrix4(src)
	err := m.GetInverse(m)
	m.Transpose()
	return err
}

// FromArray set this matrix array starting at offset.
// Returns pointer to this updated matrix.
