Objectives

By the end of this chapter, you should:

  • understand how bounding boxes can decrease rendering times;
  • know how to ray trace a number of object types including triangles and part objects;
  • understand why we can only ray trace generic versions of some objects;
  • understand the important role that compound objects play in modeling;
  • have at your disposal a variety of objects for scene construction.

This chapter allows you to start building a decent collection of object types for modeling and rendering. I’ll discuss here how to ray trace axis-aligned bounding boxes as an efficiency ...
