Opengl Acceleration - HP Vectra XW Optimization Manual

1 Your Personal Workstation's Performance Features
More 3D Graphics Performance
Texture-mapping data is used by the graphics controller to map
textures to geometric objects. The way in which a texture is displayed
for a particular component depends on that component's size, shape,
angle and relative position within the view to be displayed. The method
used for texture mapping is determined by your application.
The amount of Z-Buffer memory dedicated to texture-mapping is
determined dynamically by the application you are using.

OpenGL Acceleration

Your Personal Workstation's OpenGL Interface is able to accelerate 3D
graphics in Windows NT because of the way that OpenGL manipulates
display images.
Standard 2D graphics applications use Graphic Display Interface (GDI)
functions to manipulate images. These functions are an essential part
of the way in which Windows NT interacts with standard video drivers.
OpenGL applications replace GDI functions with OpenGL functions.
These offer a significantly increased performance with 3D graphics
applications and video drivers.
Your Vectra XW is supplied with device drivers that will enable you to
obtain this performance advantage for your 3D graphics application. To
gain maximum benefit from your AccelProT/2500 OpenGL Interface,
you must ensure that your application is configured to use OpenGL.
