To define a rendering scene in computer 3D graphics, model, view, and projection is the cleanest approach. It dissects a scene into these three logical concepts that helps us visualize the scene clearly before it appears on paper or in the form of a program. It will not be wrong to say that it is a modular approach to scene visualization.

Object: An object is a defined by a set of vertices in the 3D space. Each object has its own origin. For example, a cube contains eight vertices with respect to the origin at the center. The vertices used to define the object are called object coordinates:

Model: Modeling in 3D graphics is a transformation process where an object is displaced to an ...
