3D Object Representation Concepts

The video tutorial covers 3D object representation, focusing on polygon surfaces and their advantages in simplifying rendering. It explains how data is stored in polygon tables, including vertex, edge, and polygon tables, and provides an example to illustrate these concepts. The tutorial also discusses plane equations used in processing 3D objects.

What is the primary focus of 3D object representation in animations?

• To create realistic textures

• To enhance color depth

• To manipulate objects for animations

• To improve sound quality

Which method uses polygons to represent 3D objects?

• NURBS

• Polygon surfaces
