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.

Types of Graphic Images: Graphic images have been processed through a computer can generally be divided in two distinct categories. That image is either bitmap files or vecto
Rotation about the origin - 2-d and 3-d transformations Specified a 2-D point P(x,y), which we need to rotate, along with respect to the origin O. The vector OP has a length '
What is translation? Translation is the process of changing the position of an object in a straight-line path from one coordinate location to another. Each point (x, y) in the
