Detailed Description

OpenGL is a standard API for rendering 3D graphics. OpenGL only deals with 3D rendering and provides little or no support for GUI programming issues. The user interface for an OpenGL application must be created with another toolkit, such as Motif on the X platform, Microsoft Foundation Classes (MFC) under Windows, or CopperSpice on both platforms.

The CsOpenGL library makes it easy to use OpenGL in CopperSpice applications. It provides an OpenGL widget class that can be used just like any other CopperSpice widget, except that it opens an OpenGL display buffer where you can use the OpenGL API to render the contents.

The CsOpenGL library is implemented as a platform-independent CopperSpice/C++ wrapper around the platform-dependent GLX (version 1.3 or later), WGL, or AGL C APIs. Although the basic functionality provided is very similar to Mark Kilgard's GLUT library, applications using the CsOpenGL library can take advantage of the whole CopperSpice API for non-OpenGL-specific GUI functionality.

The CsOpenGL library is available on Windows, X11 and Mac OS X.
