.Sh DESCRIPTION
|
||
|
|
This driver creates a entry in /dev that allows programs (mostly
|
||
|
|
.Em GLIDE-based software )
|
||
|
|
to access the device memory of the Voodoo Graphics and
|
||
|
|
VoodooII 3D accellerators created by
|
||
|
|
.Em 3Dfx, Inc.
|
||
|
|
This provides an interface
|
||
|
|
for applications based on the
|
||
|
|
.Em GLIDE API
|
||
|
|
or that simply use the API
|
||
|
|
provided by the linux /dev/3dfx device to use the video device.

|
||
|
|

|
||
|
|
separately.
