One of the most common and important tasks in computer graphics is to transform the coordinates ( position, orientation, and size ) of either objects within the graphical scene or the camera that is viewing the scene. That transform might then be applied to millions of points, so the time taken to do the matrix multiplication at the start will pay off well. Announcements. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. 4 Computer Graphics. transformation is when two or more transformations are performed on a ﬁgure (called the preimage) to produce a new ﬁgure (called the image). In an affine space, one can subtract points to get vectors, or add a vector to a point to get another point, but one cannot add points, since there is no origin. • 2D afﬁne transformation has 6 degrees of freedom (DOFs) –this is the number of “knobs” we have to set to deﬁne one CS417/418 Computer Graphics.
