| After reading OpenGL® Distilled, many readers will purchase OpenGL® Programming Guide. To ease the transition from one book to another, the same style conventions are used where possible. This book uses the following style conventions: Bold OpenGL entry points, function names, and matrices Italics Variables, arguments, parameter names, spatial dimensions, and matrix components Regular Enumerant types and values, defined constants, source code, references, file names, and system paths
Blocks of code are set aside from the text and use a monospace font. This book presents OpenGL commands by using a command summary, which includes function prototypes, descriptions of the command parameters, and OpenGL version information. Here's the template for a command summary: Function prototype for the command |
A description of the command and its parameters. In the function prototype, braces indicate a set of options. As an example, consider the glLight*v() set of functions. void glLight[fd]v(GLenum light, GLenum pname, const TYPE* param); |
This prototype defines two functions: glLightfv() and glLightdv(). f and d identify the parameter data typeGLfloat or GLdouble, respectively. In the function prototype parameter list, replace TYPE with the actual data type. |
The command summary can be used as a concise reference for the command. OpenGL® Reference Manual, however, typically contains a more exhaustive reference. |
