Example – 2 (from Exams) Rotate a triangle placed at A(0,0), B(1,1) and C(5,2) by an angle 45 with respect to point P(-1,-1). The calculations available for computer graphics can be performed only at origin. It is a case of composite transformation which means this can be performed when more…

Welcome again to learn a complex topic simply. Learn by solving numerical problems. Let the theory take a back seat this time. Moving, Rotating , Zoom-in or Zoom out an object on the screen is called Transformations. There are two types of transformations in computer graphics. Geometric Transformations Coordinate Transformations…
