OpenGL Programming Guide: The Official Guide to Learning OpenGL, Version 4.3, Eighth Edition

Style Conventions

These style conventions are used in this guide:

• Bold—Command and routine names and matrices

• Italics—Variables, arguments, parameter names, spatial dimensions, matrix components, and first occurrences of key terms.

• Regular—Enumerated types and defined constants

Code examples are set off from the text in a monospace font, and command summaries are shaded with gray boxes.

In a command summary, we sometimes use braces to identify options among data types. In the following example, glCommand() has four possible suffixes: s, i, f, and d, which stand for the data types GLshort, GLint, GLfloat, and GLdouble. In the function prototype for glCommand(), TYPE is a wildcard that represents the data type indicated by the suffix.
