The major difference in 2d and 3d transformations is another dimension. 3d has one more dimension called z axis. The floor of the room is an example of 2d where in only two dimensions matters, one is length (x axis) and other one breadth (y axis). Lets include the height…

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…

In simple words , scaling means an object can be viewed differently with various scales. An object with length 3cm might appear small when viewed with a scale in meters. Cars will appear bigger if you are looking down on the cars parked at a parking lot from 2nd floor…
