Diamond Fire GL 4000
. .
. .
. .
Select models of the Compaq Professional Workstation 5100 include the Diamond Fire GL 4000
. .
graphics controller which delivers high performance 3D graphics capabilities for users working in
. .
demanding, true color environments such as 3D animation, visualization, simulation, and
. .
. .
mechanical CAD.
. .
. .
The Fire GL 4000 uses the Mitsubishi 3DPro chipset based on the REALimage rendering
. .
. .
technology from Evans & Sutherland to deliver a very high level of 3D performance. It provides
. .
hardware acceleration for OpenGL 1.0 (NT 3.51 only), OpenGL 1.1 (NT 4.0 only), and HEIDI
. .
. .
(NT 3.51 and 4.0). Support for Direct3D and HEIDI under Windows 95 will be available at a
. .
later date.
. .
. .
The Fire GL 4000 delivers industry leading 3D graphics performance by combining a
. .
. .
comprehensive set of hardware acceleration features including rasterization, texture mapping and
. .
triangle set-up with the new 3D-RAM and CDRAM memory architectures.
