Did you know?
WebSo rotation definitely is a linear transformation, at least the way I've shown you. Now let's actually construct a mathematical definition for it. Let's actually construct a matrix that … WebWhat is homogeneous transformation? Homogeneous transformation matrices combine both the rotation matrix and the displacement vector into a single matrix. You can multiply two homogeneous matrices together just like you can with rotation matrices. For example, let homgen_0_2, mean the homogeneous transformation matrix from frame 0 to frame 2.
