Module 1: Stages of Graphics Pipeline - Object Representation Techniques

The key points from this module are:
The series of steps that are involved in the generation of colour values are together called the Graphics Pipeline.
The four different types of Object Representation Techniques are:

Point Sample Representation
Boundary Representation
Space Partitioning
Sweep Representation

Boundary Representation Techniques have three sub techniques:

Mesh Representation
Parametric Representation
Implicit Representation

Some objects show a certain degree of fluidity or flexibility, which means the object's shape changes during motion or when it comes closer to other objects. Such objects are called Blobby Objects.
In the polynomial interpolation, to get the new curve, the entire process has to be recalculated. This issue is referred to as Local Controllability Issue.
There are broadly two types of Spline Representations, which are:

Interpolating Splines
Approximation Splines

B-Splines include:

Uniform B-Splines
Non-Uniform B-Splines
NURBS
