Objectives
By the end of this chapter, you should:
- understand how to intersect rays with transformed objects;
- understand why instancing is the preferred method;
- be able to transform objects through instancing;
- understand how you can model numerous beveled objects.
In this chapter, I’ll put the theory of affine transformations into practice by explaining how to ray trace transformed objects. This will give you a lot of flexibility for modeling purposes.
