This section provides information about HP’s implementation of the OpenGL product, as well as information about the standard OpenGL product.

hp’s implementation of OpenGL

Topics covered in this section are:

HP’s implementation of the OpenGL libraries

Supported graphics devices

Supported visuals

Visual support for other graphics devices

Buffer sharing between multiple processes

hp’s implementation of the OpenGL libraries

The OpenGL product does not support archived libraries.

HP’s implementation of OpenGL provides the following libraries:

libGL.sl

OpenGL shared library

libGLU.sl

OpenGL utilities library

There are two sets of libraries, one for 32-bit and one for 64-bit. The

32-bit path is:

/opt/graphics/OpenGL/lib

The 64-bit libraries are in a subdirectory:

/opt/graphics/OpenGL/lib/pa20_64

The following graphic depicts the organization of these libraries, which follows the HP-UX standard for 64-bit libraries.
