This page contains links to all resources mentioned in Chapter 6 of the textbook.  See the POV Break B page to download a copy of the right-handed basic scene template.

Interactive Visualizations

All created by Bentley University honors student Kevin Cox:

• The dot product of two vectors in two-dimensional space
• The equation of a plane in three-dimensional space
• The intersection of a line of sight with a plane in three-dimensional space

Practice Problems

I highly recommend the practice problems on dot products contained at the Learning Lesson website.

A simple ray-tracer built in JavaScript

This is useful for seeing how the concepts of this chapter (and all chapters in this part of the text) play out.  Especially if you plan to follow the programming exercises in this portion of the text, which lead you through building a simple raytracer yourself, you may want to experiment with this one to see what kind of result you can expect to achieve at the end of the exercises in question.
