3D Primitive and Composite Transformations
Previously you have studied and implemented 2D geometric transformations for object definitions in two dimensions. These transformations can be extended to 3D objects by including considerations for the z coordinate. In this unit, you will study certain methods to implement such transformations.
You must have noticed here that the translation is as simple as in 2D. Rotation however requires a little more effort in 3D. Standard rotations about three coordinate axes are simpler to perform. In order to apply rotation about an arbitrary axis, you need to have a composite transformation while scaling, shear and reflections are generalized to 3D in a natural way.
Define clipping and covering (exterior clipping)? Clipping is the process of cutting a graphics display to neatly fit a predefined graphics region or the view port. This is
Depth-buffer (or z-buffer) Method Z-buffer method is a fast and easy technique for specifying visible-surfaces. Z-buffer method is also termed to as the z-buffer method, as

What is resolution? Ans. The maximum number of points that can be shown without an overlap on a CRT is known as resolution.
Rotation - 2-d and 3-d transformations Given a 2-D point P(x,y), that we want to rotate, along with respect to an arbitrary point A(h,k). Suppose P'(x'y') be the effect of ant
