OpenGL Extension

Overview

The AL OpenGL extension provides a direct binding to OpenGL C interface routines. This extension is not yet complete -- only a subset of the bindings exists and this extension is not yet distributed publicly.

The Scheme bindings described here mirror the C counterparts as closely as possible. You should use an OpenGL textbook such as the OpenGL Programming Guide by Neider, Davis, and Woo (Addison-Wesley 1993, ISBN 0-201-63274-8) to understand what the functions actually do.

Loading the Extension

Use require to load the AL OpenGL extension. The extension is broken into two separate modules: the OpenGL module and the OpenGL motif widget module. Loading the widget module automatically loades the OpenGL module, but not vice-versa.

To load the OpenGL module only:

(require 'gl)

To load the OpenGL motif widget module:

(require 'glw-m-drawing-area)
