Conventions

This book follows a few typographical conventions:

• A new term is set in italics the first time it is introduced.

• Program text, functions, variables, and other "computer language" are set in a fixed-pitch font for example, Sphere.translateY = 5 + Cube.rotateZ.

• Code lines that do not fit within the margins of the printed page are continued on the next line, and the continuation of the line is preceded by a code continuation character .
