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.
Sequence of Steps to Generate a Full Animation The sequence of steps to generate a full animation would be as given below: 1) Improve a script or story for the animation.

Q. What is a Bezier Curve? What are blending function? Write an algorithm for generating Bezier Curves. A curve which has the following properties is called Bezier Curve: 1. A
2D Line Segment Generation A digitally plotted line is basically an approximation of infinite number of points on an abstract line segment by only a finite number of points on
Algorithms for filled-area primitives These algorithms are classified into two categories (i) Scan line algorithms (ii) Seed fill algorithms.
Figure uses three dashed arcs and one small circle. Dashed line or arc is a style attribute that can be attached with a line or a curve. In OpenGL you can use the line stipple func
