Chapter Overview:
In this chapter, you explore further transformations and begin to combine transformations
into animations. You: (1) are introduced to a matrix transformation library that hides the
mathematical details of matrix operations; (2) use the library to quickly and easily combine
multiple transformations; and (3) explore animation and how the library helps you
animate simple shapes. These techniques provide the basics to construct quite complex
WebGL programs and will be used in the sample programs in the following chapters.
