4.3.1 Using OpenGL Applications
In addition to a generic OpenGL display driver, Windows NT OpenGL includes a
mechanism by which OpenGL rendering can be performed by vendor-supplied display
drivers. Compaq provides such an OpenGL display driver in the PowerStorm 300 Software
product. This driver takes advantage of hardware features that improve rendering
performance and quality, and is used with the PowerStorm 300 graphics device.
When an application requests a pixel format, Windows NT OpenGL will satisfy the
request with the pixel format that best fits the description. This pixel format can be one of
the following:
•
A hardware pixel format, supported by the PowerStorm 300 OpenGL driver
•
A software pixel format, supported by the generic Windows NT OpenGL driver
4.3.2 Developing OpenGL Applications on Intel Platforms
This section provides information for developing OpenGL applications that optimize the
PowerStorm 300 graphics device on Intel platforms.
4.3.2.1 Pixel Format Support
The PowerStorm 300 driver and device, in combination with Windows NT OpenGL,
support a fully compliant implementation of OpenGL. Color index mode support is
provided by the Windows NT generic OpenGL implementation, and thus is not hardware-
accelerated.
On the PowerStorm 300 device the display driver supports the pixel formats listed in
Table 4-1.
