3091.0. "Image processing, animation, 5000 ?" by ORIWS::ORI (Ori Kresh @ISO, DTN 882-3442, DEC Israel SWAS) Wed Jul 18 1990 11:40

Hello,

I am evaluating an RFP involving fast image processing on a workstation.

The workstation will receive, from an external source, bitmaps representing 
cross-sections of a 3D body.

A number of processing capabilities are required:

1. The bitmaps will be displayed in animation, 30 frames/sec.

2. On-the-fly zooming, by pixel interpolation, will be performed during the
   animated display

3. A solid 3D rendering of the body will be constructed from the
   cross-sectional bitmaps.

4. The 3D body will be displayed, with 3D transformations applied to it in real
   time (rotation, scaling, etc. using a dial box 


The DS5000 is considered as a platform. The main problem is the image
processing. It seems that the graphics pipeline is not very good in this type
of application.
The idea is to use an external image processor.

Questions:

1. Can the PXG's i860 (N10) be programmed and accessed independently ?
2. Is there an i860-based image processing board available/planned for the
   Turbochannel ?
3. Are there other image processors suitable for this type of application ?
4. Will the PXG be suitable for this application without an external image
   processor ?

cross posted IN MIPSCO, DECWINDOWS, and IMAGING

Cheers,

\Ori
