GLINT04 Omnicomp 3Demon VR
Description
This item is from the PC 3D Graphics Accelerators FAQ, by Blair MacIntyre with numerous contributions by others. (v1.2).
GLINT04 Omnicomp 3Demon VR
(was Media Labs Inc. 3DMedia)
Formerly the Media Labs Inc. 3DMedia. The name changed when Media Labs was aquired by Omnicomp. The former 3DMedia SR (which I'll call the 3Dmedia VR (SR?)) is a true high performance 3D accelerator based on the 3DLabs GLINT 300SX chip.
The 3Demon VR (formerly the 3DMedia SX) provides the same features as the SR, plus additional features such as genlocking to eliminate annoying scrolling bars due to magnetic interference between two monitors in a dual-headed configuration. Furthermore, in provides an on-board studio quality encoder which outputs video in NTSC, PAL or S-Video formats.
3Demon VR (SR?)
3D Acceleration:
* Similar to other GLINT 300SX boards
Flexible output:
* Software selectable standard as well as custom display
* formats, interlaced and non-interlaced, are available with a
* maximum resolution of two million pixels.
Optimized Bandwidth
* PCI local bus, rev 2.0.
* Target and Read Master interface achieves 20M pixel/second sustained image download rate.
* Refresh rates in excess of 200Hz.
Product Specification:
* PCI Rev 2.0 Target and Read Master interface
* 4M Byte framebuffer
* 4 MByte localbuffer. Extra 4M available as an option.
* Supports 64-bit/pixel, 8/8/8/8 for RGBA, 24-bit depth, 4-bit stencil, 4-bit fast clear
* Double buffering at all resolutions and depths.
* ISO and VESA Display refresh rates.

3Demon VR
All of the features described above, plus:
More flexible output:
* Support for stereoscopic, field sequential RGB and VR displays is implemented in hardware reducing host overhead.
* Television and video tape recorders are driven by the studio quality encoder. Square pixel, CCIR and 4x video resolutions can be selected in NTSC, PAL or S-Video format.
Phase locking:
* Line-lock to external sync signals, such as VGA or other sources, enables windowing and external video multiplexing.
* An independent 3D window can be opened within the GUI display, such as VGA, by activating the line-locking feature.
* Independent color depth between the GUI and 3D graphics is now possible, depending on the operating system used.
Product Specification additions:
* Max 135MHz video clock.
* Standard and custom resolutions up to 1600x1200
* Supports standard, stereoscopic, field sequential RGB, VR Glasses and other display devices.
* Programmable video clock.
* Line-lock to external sync signals.
* Studio quality encoder with support for different NTSC, PAL, and S-Video resolutions.
* Output Support in addition to those above:
RGB Resolution NI Colors supported Max Refresh
