- While we're at this does anyone have, or know how I could get, a comparative
- listing of pc-based, and hopefully modular, graphics engine type hardware.
- This stuff, usually priced between $5k and $50k, exists and is often
- very powerful (e.g. boards made by XTAR of San Diego). This market is
- moving fairly slowly now, or was when I last examined it. These systems are
- often optimized for "real-time" simulation as opposed to CAD/CAM type
- visualization requirements. The boards for the XTAR system were spec'd at
- producing about 60,000 polygons/sec (non-antialiased, no texture maps,
- but with hidden surface removal, and other interesting capabilities such as
- moving objects and levels-of-detail). These boards are also programmable
- in micro-code for adventurous types. The cost was, however, $20k. Have
- things gotten any cheaper and/or better?
