The exhibition presents the untold story of the Vatican Library as the intellectual driving force behind the emergence of Rome as a political and scholarly superpower during the Renaissance.  The exhibit will be on display in the Jefferson Building of the Library of Congress from January 8, 1993 through April 30, 1993.  The online exhibit will be available by anonymous FTP indefinitely.       The exhibit is divided into nine (9) sections:  The Vatican Library, Archaeology, Humanism, Mathematics, Music, Medicine & Biology, Nature Described, A Wider World I: How the Orient Came to Rome, and A Wider World II: How Rome Went to China.  Each section consists of its own sub-directory within the /exhibit directory and contains the exhibit text for that section and separate JPEG image files for each object.  This online exhibit includes not only objects from the Library of Congress exhibit, but also the alternate objects (brought from Rome to be used if there were a problem with one of the primary objects) and items omitted later in the planning process.       This exhibit will be of interest to Medieval and Renaissance scholars in particular, but also to art historians, historians of science or medicine, early music scholars, students of the humanist movement, students of printing and the printed word, theologians, scholars of both Far and Near Eastern studies, and to librarians and information professionals.  Please get the README file for details on what files this exhibit contains.  If you have questions about how to use FTP, speak to your local computer support person.  If you have questions or comments about the CONTENT of the exhibit, please write to vatican@kell.loc.gov while if you have any questions or comments on the SYSTEM please contact me.  -- K.D. Ellis
I've had pretty good success autotracing line art with Adobe Streamline 2.0. The key to controlling excessive points, etc. is to take some time and do some test conversions using various Tolerance settings.
I currently have some grayscale image files that are not in any standard format.  They simply contain the 8-bit pixel values.  I would like to display these images on a PC.  The conversion to a GIF format would be helpful.  This conversion can take place either on a PC or on a UNIX system and I could then download it to the PC. Can anyone suggest where I can find software to do this?  Alternatively, I may have to write my own conversion program.  In this case, could someone tell me where I can find the GIF format specification?  Please e-mail me directly at: shayla@shannon.jpl.nasa.gov
Hi.  I'm writing a program to convert .dxf files to a database format used by a 3D graphics program I've written.  My program stores the points of a polygon in CCW order.  I've used 3D Concepts a  little and it seems that the points are stored in the order they are drawn.  Does the DXF format have a way of indicating which order the  points are stored in, CW or CCW?  Its easy enough to convert, but if I don't know which way they are stored, I dont know  which direction the polygon should be visible from.  If DXF doesn't handle this, can anyone recommend a workaround? The best I can think of is to create two polygons for each one in the DXF file, one stored CW and the other CCW.  But that doubles the number of polygons and decreases speed...  Thanks in advance for any help,
Can anyone around here point me to information regarding STEREOSCOPIC images? I believe I saw some at a show room in Texas (Lone Star Illusions)  and  they were amazing.  I've now heard that they were created with a simple  graphic program.  Does anyone have any of these images digitized??   I really want to find a out as much as I can..
I'm not sure if you got the information you were looking for, so I'll post it anyway for the general public.  To load an image on your root window add this line to the end of your .xsession file:   xloadimage -onroot -fullscreen <gif_file_name> &  This is assuming of course you have the xloadimage client, and as for the switches, I think they pretty much explain what is going on. If you leave out the <&>, the terminal locks till you kill it. (You already knew that though...)  Hope this helps.

I was wondering if anyone has ever seen/heard of a utility that converts any type of image format (gif,tiff,pcx,bmp,jpeg,etc.) to an ascii representation.  I have seen some very sophiticated art in ascii format, but never was I able to find the author or any program that may have converted the data from a picture format.  Any help or leads would be great. Thanks in advance. Danny Dunlavy
Excuse the sheer newbieness of this post, but I am looking for a decent PaintProgram which will save to various file formats (.BMP  .PCX  etc etc) via ftp, freeware, or shareware.  I would like to check out the available programs for little $$ before I check out the commercial market.  Thanks in advance for any help or direction you can give me.
Dear Binary Newsers,  I am looking for Quick C or Microsoft C code for image decoding from file for VGA viewing and saving images from/to GIF, TIFF, PCX, or JPEG format. I have scoured the Internet, but its like trying to find a Dr. Seuss spell checker  TSR. It must be out there, and there's no need to reinvent the wheel.  Thanx in advance.  //////////////

Unfortunately the poster wants to use an internal and an external modem so a switch isn't going to help them.  If you aren't using your com ports for anything else, just define them on different com ports.  Define your internal modem to be say, com1, and your external modem to be com3.  You really shouldn't have to worry about interrupt conflicts since you won't be using both modems at the same time :).
RADIOSITY SOURCES WANTED !!! ============================  When I read the comp.graphics group, I never found something about  radiosity. Is there anybody interested in out there? I would be glad  to hear from somebody. I am looking for source-code for the radiosity-method. I have already read common literature, e. g.Foley ... . I think little examples could  help me to understand how radiosity works. Common languages ( C, C++,  Pascal) prefered. I hope you will help me!

This may be a fairly routine request on here, but I'm looking for a fast polygon routine to be used in a 3D game.  I have one that works right now, but its very slow.  Could anyone point me to one, pref in ASM that is fairly well documented and flexible? 	Thanx,             //Lucas.

Just to clarify, the 3D routines that are mentioned in various places on the mac are in a libray, not the ROM of the mac.  A few years ago before I knew anything about implementing graphics, I came across a demo of the Apple GrafSys3D library and it actually did a lot.  However, it is quite limited in the sense that it's a low-level 3D library; your code still has to plot individual points, draw each line, etc ad nauseum.  It has nothing on GL, for example, where you can handle objects.  Other things to consider when talking about Apple's old 3D GrafSys library:  * Unsupported;  never was and no plans exist to do so in the future  * Undocumented; unless you call header files documentation...  If one knows something about graphics, you could probably figure it out, but I'd assume there's better software available that gives better output and is, at the same time, programmatically nicer (i.e. easier to program).

Does anyone know of a program for the PC that will take AutoCad DXF format files and convert them to a raster format, like PCX, GIF, etc? Thanks in advance.... 				ED
Does anybody know what Delaunay Triangulation is? Is there any reference to it?  Is it useful for creating 3-D objects? If yes, what's the advantage?  Thanks in advance.
I have a problem with intersections between two surfaces. Does anybody have a easy to understand algorithm for that or maybe even C source??
I searched the U Mich archives fairly thoroughly for 3D graphics packages, I always thought it to be a mirror of sumex-aim.stanford.edu... I was wrong. I'll look into GrafSys... it does sound interesting!  Thanks Cheinan.
I have some color gifs which I would like to archive in a much smaller size using a grayscale palette of 16 shades. The quantization to 16 grays introduces some ugly bands in the pictures, which can be nicely eliminated by dithering. Up to now I have used XV to process the images, but now I would like to automate the procedure.  The problem is that XV can't (I think) convert images automatically, and the obvious alternative PNMPLUS (PPMQUANT and PNMDITHER) don't even get close to XV's quality. PNMDITHER apparently dithers in RGB, even though the images are in grayscale. The dithering routine in XV seems to use the natural image colors for the dither. Is this or any similar routine available in the public domain? If so, where?

These standards should facilitate the creation of REAL_TIME Online applications that make use of Voice, Video, Telecommuting, HiRes  graphics, Conferencing, Distant Learning, Online order entry, Fax,in addition these dicussion would assist all to better understand how SGML,CALS, ODA,MIME,OODBMS,JPEG,MPEG,FRACTALS,SQL,CDrom,cdromXA,Kodak PhotoCD,TCL, V.FAST,EIA/TIA562,can best be incorporated and implemented to develop TELEMATIC/Multimedia applications....   We want to be able to support DOS, UNIX, MAC, WINDOWS, NT, OS/2  platforms. It is our hope that individuals,developers, corporations, Universities, R & D labs would join in in supporting such an endeavor.   This would be a NOT_FOR_PROFIT group with bylaws and charter. Already  many corporation have decided to support OTG (Open TELEMATIC Group) so do not  delay joining if you are a developer   An RFD has been posted to form a usenet newsgroup and a FAQ will soon be  be compose to start promulgating what is known on the subject. If you would like to be added to the mailist send email or mail to the address below.    This group would publish an electronic quarterly NAPLPS/JPEG newsletter as well as a hardcopy version. We urge all who wants to see CMCs HiRes based applications & the NAPLPS/JPEG G R O W,  decide to join and mutually benefit from  this NOT-FOR_PROFIT endeavor.

We need terrain data for a visualization research currently taking place in Tel-Aviv university. We have two databases that we are currently working on, but we would like to work on more databases, possibly more complicated  and ones that will give prettier images.  Before I describe what kind of data we need, let me mention that we are  going to present a paper titled "Photo-Realistic Imaging of Digital Terrains" which describes the research and the results, in the EUROGRAPHICS'93  conference in Barcelona, this september. We are going to show a video-tape  with some of our results, so any good data that we will receive will be  presented in the tape, with a mention of the donator.  We are working on databases consisting of aerial or satelite photographs,  and terrain elevation maps (DTM).  Each database consists of a 2D array of height values (any data format can be used for each value), and a corresponding 2D array of color values (can be gray-level, 256-color value or full 24-bit R/G/B values. Other format can also be used). We work on 512X512 and 1024x1024 resolution databases.  If anybody has access to this kind of data, or knows where we can get such data files, please respond in this news group, or - better - email us directly :  amit@math.tau.ac.il    (Amit Shaked), or danny@indigo.bgu.ac.il (Daniel Cohen)
Can someone give me the title of a good VGA graphics programming book? Please respond by email. Thanks!  			--Yuan

Greetings,     I have an Epson HI-80 4 pen plotter forsale.  It emulates an HP 7570 or 7574 - I'm not sure which.  It has an option board on it that does the emulation.  It has a serial interface with Hardware handshake. I also have 340 Pens for it as follows:  10 packs of 4 Black Oil based, 16 packs of 4 Red,Green, Blue, and Black pens, 22 packs of 4 Aqueous Black, 7 packs of 4 Aqueous R,G,Blue,Black,  1 pack of 6 Aqueous Multi color pens,  and 114 assorted non-packaged pens mostly colored.      The plotter is used.  I have tested it using the Windows drivers for HP 7570 and HP 7574 and both worked fine.  It accepts either A or B sized paper. (8.5 x 11 or 11x17).      I figure that the plotter is worth about $300 and the pens are worth at least another $200 more..  One thing is certain, you won't need to purchase any pens for quite a while...  All of the packaged pens were sealed so they are all still fresh.  The rest were capped and seem to function as well.      I'd be willing to sell the pens seperate if anyone is interested in just them.      I'm selling it because I got a HP LaserJet and I don't need color.      I'd like $350 or best offer...      -Chert
I'm a mac user who wants to use some of the rayshade models I've built using macrayshade (rayshade-M) with Stratavision 3d.  Since Stratavision can import many different model files I thought this would be a cinch... but I haven't been able to find a simple translator that will work on the mac.  Any ideas?  Stratavision 3d should be able to import:  DXF MiniCAD Super 3d Swivel 3d professional  out of the box and:  RIB IGS  with externals.  Also, if anyone knows of any other translator externals available for Stratavision 3d (esp. Rayshade!) please e-mail me!  BTW, I'm going to send mail to the rayshade usrs mailing list tomorrow (I misplaced the address) but since most users of rayshade do not seem to operate with macs, I'm not getting my hopes up...  thanks in advance,
Hi net! Due to further investigation I would like to study the following article: 	Peterson, "Ray tracing general B-Splines", 	Proc.
