Has anyone already written one that they are willing to share, or does anyone know of one in the public domain? I am hoping to have the emulator work with the CGA board first, and later with the EGA board. Thanks for any suggestions.

Joel) Date: Tue, 24 Jun 1986 08:32:18 EDT Subject: Need Beta Testers for Educational Software NOTICE: ====== I have recently completed the first release version of an educational graphics package called GRAPHIX. Therefore, I am in need of several beta testers. GRAPHIX requires an IBM PC with a minimum of 256K RAM, a Color/Graphics adapter and an IBM or Hewlett-Packard plotter. As a beta tester you will be given the most current version of GRAPHIX, a manual, a set of forms to fill out and a self-addressed stamped envelope to return it all in. If you are interested, contact: William J. Joel Division of Computer Science & Math Marist College Poughkeepsie, NY 12601 (914) 471-3240 x432 or x371 JZEM@MARIST.BITNET Please note, that because of the educational nature of the software, I will only accept educators as testers; no administrators or students. Thank you. ------------------------------ From: "Mike Purtell" Date: Tue, 1 Jul 86 19:07:08 CDT Subject: Parallel Processing applied to Ray-tracing I am currently interested in learning as much as I can about ray-tracing. Eventually I plan on applying the power of parallel processing to the generation of ray-traced graphics. Does anyone know of anyone else doing any applications of parallel processing to ray-tracing? Could any of you point me towards some good books or papers on ray-tracing and/or application of parallel processing to ray-tracing? It would be much appreciated. Thanks in advance, Mike Purtell ------------------------------ From: John Brugge Date: Wed 2 Jul 86 12:46:31-PDT Subject: Lisp on an IRIS? We have just received an SGI IRIS workstation at our lab, and have heard that there is (or soon will be) an implementation of Common Lisp, with a Flavors package, that will run on it from Franz, Inc. Has anybody heard of such, or perhaps used it? All of our code is currently in C, but the prospect of a Lisp development environment is enticing. Any information would be appreciated.

I am looking for greyscale to halftone conversion routines. I have a greyscale to halftone filter for 4x4 halftones (17 levels); but before I try and generalize the routine, I'd like to find out if someone else already has done a general greyscale to halftone filter.

I have just finished a survey on this piece of hardware for the last 4 months. I will give you two options, I forgot the third however the third one on works on an IBM machine. Well, they are MIP-1024 Real-time image processor for multibus VIP-1024 Real-time image processor for VMEbus. Note that either one of them has the 512 version as well and also they all can be configured with VMEbus/Multibus adaptors (vice vesa is also true). They will allow you to grabe a frame from a video disc player, a video tape player or an instructment that produce PAL/NTSC composite signal. The frame grabe speed within one video frame rate time 1/25 second or 1/30 second depending on whether your use the European or American Standard. One board costs around A$6,050.00 for the VIP-1024 and A$5,088.0 Note that one board will give your variation in intensity of grey. If you want full colour then 3 of these boards are needed (one master two slave). However pseudo colour can be achieved with one board using a different configuration. I think the agent could tell you the best of doing this. I will give you the headquarter in Canda. Matrox Electronic System. 1055 St. Regis BLVD, Dorval, QUE. H9P 2T4, Canada. Tel: (514) 685-2630 Telex: 05-822798. The feature that is very distinguish is that it can grabe a frame by using one command from the host computer and digitised it and finally stored in it's frame buffer in one video-frame rate time. The configuration of the frame buffer is up to you either 512 X 512 or 1024 X 1024. I am in the process of purchasing 3 MIP-1024 boards configured with 4 frame buffer each with resolution 512 X 512. It will cost us around A$20,000. I am not sure whether you are interested in my research here, it is dealing with perspective display of terrain (using terrestrial photogrammetry) and overlay it will symbols. let me know if you are interested. Could you let me know what exactly you are doing there. I will be using it either on the SUN 2/120 (multibus) or SUN 3/160M (VME bus) with multi/VME bus adaptors. NB that there are a lot of features I didn't mention about this hardware such as convolution, averaging and so on. Check with Matrox. They will provide you with the required detail. But don't hesitate to contact me if you need more information. Good luck. My previous two trials were being rejected, so I have no choice but to send to mod.graphics. -- Tang Guan Yaw/PatricK ISD: +61 62 68 8170 Dept.

El-Ghazzawy) Subject: Video Animation Summary: Expires: Followup-To: Distribution: mod.graphics Organization: Washington U. in St. Louis Keywords: Video Animation I (Jon Elson) have a video animation controller nearing production. It supports 3 models of Panasonic Video Recorder -- the 9600 (VHS) the 8500 (3/4" Umatic format) and the AU-300 (1/2" M format, broadcast quality, 20 min. / tape). The VHS machine costs about $2600, the 3/4" costs about $5500 and the AU-300 is out of nearly everybody's budget at $18000. The controller is connected to the host computer by a simple RS-232 serial line, and is sent commands of the form INSERT 10 12345 to insert 10 frames at frame # 12345. It replies DONE when the frames have been captured on the video tape. This system gives absolute single frame accuracy across an entire video tape by recording a timing track on the second audio track of the tape. SMPTE time code is not used because the complexity and cost of the decoder is more than this whole unit costs. I am planning to produce these units at $2000.00, ready to plug in and go. (The recorder of your choice is extra, of course.) One of the prototypes is cranking out Anheuser-Busch ads for network TV spots, and other spectacular video work.

Does anyone know where I can get hold of a software package which is in public domain that can do that. Note that it should be able to run on a SUN 2/160 colour or SUN 2/120 monochrome or SUN 3/160C running UNIX 4.2 BSD. Thanks. -- Tang Guan Yaw/PatricK ISD: +61 62 68 8170 Dept.
