08: construct the following matrices: a) a matrix to scale by a factor of 2 about the plane through the origin perpendicular to the vector (0.5, -0.1,0.9) b) a matrix to orthographically project onto the plane through the origin perpendicular to the vector [0.5, -0.1,0.9) c) construct a matrix to reflect orthographically about the plane through the origin perpendicular to the vector (0.5, -0.1,0.9)
