Homogeneous coordinates of a 3D point (x,y,z,1) Transformation will be performed using 4x4 matrix. Download Presentation. rotation.
In 2D, a rotation just has an angle. In 3D, specifying a rotation is more complex. basic rotation about origin: unit vector (axis) and angle. convention: positive rotation is CCW when vector is pointing at you.
