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.
Suppose here, one allows 256 depth value levels to be employed. Approximately how much memory would a 512x512 pixel display necessitate to store z-buffer? Solution : A system w
Clipping and 3D Primitives This unit introduces you to three important concepts of Computer Graphics. After that discusses the concept of clipping, which means removal of objec

Important Notes for Negative Accelerations Note : Having projections of points on curve, above Y axis we will obtain a pattern similar to figure 8 that is needed to produce ne
Anti Aliasing - Modeling and Rendering It is a method for enhancing the realism of an image through eliminating the jagged edges from it. Such jagged edges or "jaggies", appe
Example1: Translate a square ABCD along with the coordinates as: A(0,0),B(5,0),C(5,5),D(0,5) via 2 units in x-direction and 3 units in y-direction. Solution: We can show the
