Chapter Overview:
This chapter builds on those basics by exploring how to draw more complex shapes and
how to manipulate those shapes in 3D space. This chapter looks at: (1) the critical role of
triangles in 3D graphics and WebGL’s support for drawing triangles; (2) using multiple
triangles to draw other basic shapes; (3) basic transformations that move, rotate, and
scale triangles using simple equations; and (4) how matrix operations make transforma-
tions simple.
