To everyone who wants fonts in Vivid/POV/Polyray. The Borland BGI font converter is VVFONT18.ZIP. This program can be found on FTP.INFORMATIK.UNI-OLDENBURG.DE directory pub/dkbtrace/utils. Also WUARCHIVE has mirrored this site (directory graphics/graphics/mirrors/ ftp.informatik.uni-oldenburg.de/pub/dkbtrace/utils. There are more nice utilities present in this directory. A new version of Polyray 1.6 (for those asked for it) can be found on the  same sites but in the directory INCOMING instead of UTILS (PLY16386). Also in this directory POVSHELL and PV3DV060 could be found. Have a nive raytrace time. Peter

vamilliron:  Yes, Intel's PCI is (another) Local Bus standard, which can be used for graphics, although I believe Local Buses can be used for other things, too.  As far as I know, though, PCI Local Bus  would compete with VESA Local Bus, not the VESA graphics standard, but others more enlightened might be able to shed more light on this matter.

Hello,  Hello,       I was wondering if anyone knew of a PC or MAC implementation of the marching cubes algorithm that will output the individual faces.  If there is no such application, might there be some C source code that I could modify to implement the algorithm and get to the individual faces.  Thanks in advance Sincerly  Tracy
I'm interested in find out what is involved in processing pairs of  stereo photographs.  I have black-and-white photos and would like  to obtain surface contours.

Please email and/or post to comp.sys.sgi.graphics your responses.  Thanks,
I was chaining around in the anonymous ftp world looking for 3D Studio meshes and other interesting graphical stuff for the program, and found a few files with the extension 3D2.

On a more cheerful note, perhaps hackerism/hacking isn't completely dead.  As someone else said, take the GNU offerings for example - free, redistributable and  often better than the commercial stuff.  Take also the number of papers published every year in all the fields of computer science - the vast majority of these papers detail original work of real, often exceptional merit - and the authors are sharing this knowledge.

The idea is to clip one polygon using another polygon (not necessarily rectangular) as a window.  My problem then is in finding out all the new vertices of the resulting "subpolygons" from the first one.  Is this simply a matter of extending the usual algorithm whereby each of the edges of one polygon is checked against another polygon???  Is there a simpler way??  Comments welcome.

As someone who would _love_ to see XV go to 24 bit, this would be plenty for me.      a) XV can Load a 24 bit image, and display it in all it's 24 bit glory on 24 bit X displays.     b) All other operations (Crop, Dither, Smooth, etc.) are not supported on 24 bit images.  how hard would this be?

I'm interested in obtaining the highest possible image capture in a  MS-Windows application. The resulting image must go to print and high resolution is the name of the game. I'm familiar with (and unhappy with) composite video capture technology. What kind of resolution can I get out of an SVHS signal?  What about RGB (and who makes RGB cameras)? Does anyone have any experience with digital cameras?

I am looking for some information of hidden line removal using Roberts algorithm.  Something with code, or pseudo code would be especially helpful.  I am required to do this for a class, due Monday (we have very little time to implement these changes, it is a VERY FAST paced class).  The notes given in class leave a LOT to be desired, so I would vastly appreciate any help.  Actually any algorithm would be nice (Roberts or no).  The main problem is two objects intersecting in x and y dimensions, need to know which lines to clip off so that one object will appear in front of another.  If you can give me an ftp address and filename, or even the name of a good book, I'd REALLY appreciate it.
I do not know if I am hitting the right news groups or not, any help in the right direction is more than welcome.  I need help finding a company that will take photographic images scanned in and modified by Adobe Photoshop and turn them into thermal prints or negatives.  I am looking for a place as close to North Carolina as possible.  The images will be created on a Macintosh Quadra 800 running Adobe Photoshop and will then be stored in whatever format the vendor requires, perhaps 88M cartridges?      The images will be black and white photographs scanned in with a 1200 dpi scanner then modified/corrected by Adobe Photoshop.  If anyone could help me or even give me phone numbers to people who could I would be very grateful.      Also if anyone else is doing what I am planning I would be happy to hear from you with any advice you might provide as to the computer system you use and/or any peripherals or software.  It seemed the Quadra 800 would be my best bet to modify photographic images.  I am planning on buying a Quadra 800 with 32Megs of RAM, a 510Meg Hard Drive, a 1200 dpi scanner, 17" Sony  monitor and a 88Meg cartridge drive and perhaps a CD ROM.  I am new to computers and any advice would be great.

I've got an old demo disk that I need to view. It was made using RIX Softworks.   The files on the two diskette set end with: .scf  The demo was VGA resolution (256 colors), but I don't know the spatial   resolution.  First problem: When I try to run the demo, the screen has two black bars that   cut across (horizontally) the screen, in the top third and bottom third of the   screen. The bars are about 1-inch wide. Other than this, the demo (the   animation part) seems to be running fine.  Second problem: I can't find any graphics program that will open and display   these files. I have a couple of image conversion programs, none mention .scf   files.  The system I am using: 486clone, Diamond Speedstar 24, Sony monitor.  Any suggestions?
I wanted to know if any of you out there can recommend a good book about graphics, still and animated, and in VGA/SVGA.  Thanks in advance

Moscow Scientific Inductrial Association "Spectrum" offer        VIDEOSCAN vision system for PC/AT,wich include software and set of        controllers.                       SOFTWARE              For support VIDEOSCAN family program kit was developed. Kit        includes more then 200 different functions for image processing.             Kit works in the interactive regime, and has include Help for        non professional users.             There are next possibility:        - input frame by any board of VIDEOSCAN family;        - read - white image to - from disk;        - print image on the printer;        - makes arithmetic with 2 frames;        - filter image;        - work with gistogramme;        - edit image.        - include users exe modules.                       CONTROLLER VS9         The function of VS-9 controller is to load TV-images into  PC/AT.        VS-9 controller allows one to load a fragment of the TV-frame from        a field of 724x600 pixels.        The clock rate is 14,7 MHz when loading an image with 512 pixel in        the line and 7,4 MHz when loading a 256 pixels image. This        provides the equal pixel size of input image in both horizontal        and vertical directions.        The number of gray levels in any input modes is 256.        Video signal capture time - 2.5s.                       CONTROLLER VS52         The purpose of the controller is to enter the TV images into a IBM        PC AT or any other machine of that type. The controller was        created on the base of modern elements, including user        programmable gate arrays.        The controller allows to digitize a input signal with different        resolutions. Its flexible architecture makes possible to change        technical parameters. Instead of TV signal one can process any        other analog signal (including signals from slow-speed scanning        devices).        The controller has the following technical characteristics:        - memory volume - from 256 K to 2 Mb ;        - resolution when working with standard video signal - from 64x64        to 1024x512 pixels ;        - resolution when working in slow input regime - up to 2048x1024        pixels;        - video signal capture time - 40 ms.        - maximum size of a screen when memory volume is 2Mb - 2048x1024        pixels ;        - number of gray level - 256 ;        - clock rate for input - up to 30 MHz ;        - 4 input video multiplexer ;        - input/output lookup table (LUT);        - possibility to realize "scroll" and "zoom";                     - 8 lines for external synchronization (an input using external        controlling signal) ;        - electronic adjustment of black and white reference for analog -        digital converter;        - possibility output image to the color RGB monitor.        One can change all listed above functions and parameters of the        controller by reprogramming it.                 IMAGE PROCESSOR VS100

Greetings all. 	According to a FAQ I read, on 30 July 1992, Joshua C. Jensen posted an  article on bitmap manipulation (specifically, scaling and perspective) to the  newsgroup rec.games.programmer. (article 7716) 	The article included source code in Turbo Pascal with inline assembly  language.  	I have been unable to find an archive for this newsgroup, or a current  email address for Joshua C. Jensen. 	If anyone has the above details, or a copy of the code, could they  please let me know.	Many thanks. 					Yours gratefully, etc.  Myles.

I don't think speed has been determined, since it has never run on Intel chips. But on the Amiga's Motorola Chips, it was one of the fastest true 'Ray Tracers'  I don't think Impulse would port it over and not take speed into consideration.  In terms of features, and learning curve... ALL that you stated for 3DS is also true for Imagine, and lots more... But I'll have to admit that after 3 years of use on the Amiga, the learning curve is very steep. This is due ONLY to the manual. It is realy BAD. However, there is a lot of after market support for this product, including regular 'Tips' articles in many magazines such as "AVID and a great book by Steve Worley called "Understanding Imagine 2.0" This book i is not just recommened, IT IS A MUST!
