After fixing up a few bugs (3 missing constant definitions plus a couple of other things) I got it to compile & link, but after starting client & server I just get a black window; sometimes the client core dumps, sometimes the server, sometimes I get a broken pipe, sometimes it just sits there doing nothing although I occassionally get the cursor to become a cross-hair in dog-fight, but that's it.  I've sent word to the author plus what I did to fix it last week, but no reply as yet.
Hi,   Anyone has a converter from BMP to any format that xview or xv can  handle?  This converter must run Unix..  I looked at the FAQ and downloaded several packages but had no luck...  thanks in advance.  ed

Does anyone know of a fractal terrain generator for Mac, something 	I could hopefully import into a 3D program like Swivel or Stratavision? 	I know Infini-D has built in capabilities, but I don't have access to 	Infini-D. I downloaded two programs from Umich, in graphics/fractals, 	but both were from 1990-91 and crashed under System 7.

Yes I am aware CorelDraw exports in SCODAL. Version 2 did it quite well, apart from a few hassles with radial fills. Version 3 RevB is better but if you try to export in SCODAL with a bitmap image included in the drawing it will say something like "cannot export SCODAL with bitmap"- at least it does on my version.  If anyone out there knows a way around this I am all ears.  Temporal images make a product called Filmpak which converts Autocad plots to SCODAL, postscript to SCODAL and now GIF to SCODAL but it costs $650 and I was just wondering if there was anything out there that just did the bitmap to SCODAL part a tad cheaper.

No, MIS folks have infinite budgets of death, and they also get parts of their budget allocated "upgrades", "maintenance", and "new purchases", and a lot of IBM mainframe purchases are actually "leases" and so is the software.  Basically, the engineers who have tight budgets, i.e. the coders and designers of a company, bitch and moan when they drop 15,000 on a  Sparc 1 only to see a faster machine appear a year later.  MIS types upgrade once every 5-10 years, and their costs are amortized and depreciated over a longer period, and the budget office justifies the expense because they actually use the machines for accounting, payroll, etc.  Now, if the budget office was dependant on the engineers for some reason like payroll and accounts, you'd sure as hell see every engineer with a new Cray on his desktop every year. :-)

I have an ATI Graph. Ultra Pro VLB w/2 megs, and have a small question about Graphics Workshop for Windows.  When I exit from it it says my current driver can handle on 32768 colors when I am actually in  1024x768x65000 color mode.  Is this a driver problem, a GWS error, or what?  I am using the 1.5(59) driver under Win 3.1.  It correctly states that I can display 16M colors when I switch to 800x600x24bit, though. Another question- Anybody know of any Viewers that support this card other than Windows viewers? Any help would be appreciated.
Help! How do you write to the second bank/page of memory when in VGA 320x200x256 colour mode?. ie: to perform page flipping animation and buffering of the screen.      I have tried using the Map Mask Registers, but this does not perform the required task (Although it does do something).  Note: It *must* be able to work on a standard VGA (ie: not necessarily a SVGA card).
I am trying to find out anything I can about available documentation for IGES and e00(Arc/Info) formats.  If you know anything about these formats (or just one) PLEASE send me a note.  I don't read this group, so please send responses to:  mike@prc.utexas.edu  Thank You
Anyone who thinks that TIFF is too complex hasn't dealt with 	CGM, ASN.1, CDA, DCA, SGML, or any one of a number of other 	very successful file format.  People seem perfectly capable 	dealing with these others.  Dealing with the format of TIFF 	is frankly less difficult than dealing with the DCT, LZW, and 	FAX encoding of the image data.  The majority of the libraries 	which deal with TIFF are dedicated to these other issues rather 	than with simply decoding the tags and parameters.  	Perhaps people are overwhelmed in comparison with some rather 	simpleminded formats such as GIF, PCX, and BMP, but to suggest 	that TIFF is so complex as to be doomed to failure is ludicrous.  	That doesn't mean that GIF isn't fine, but don't even thing about 	using it in many instances.  GIF is very nice for use in low-end 	photos applications and for screen grabs and such, but it would 	never do for high-volume or high-resolution systems.  FAX is nice, 	but it doesn't do color (and GIF doesn't do B&W all that well). 	JPEG is nice for high-resolution color, but is slow for low-end.  	The advantage TIFF brings to the table is its ability to handle 	all these situations (and then some).  Naturally it's more complex. 	But I'ld rather propose TIFF imaging solutions over imaging 	systems based on having to deal with 3-4 file formats anyday.  	You may find that TIFF is too complicated for your personal tastes 	but please don't wrail against it's complexity.  The complexity 	it contains is required to provide the functionality it does and 	doesn't come close to the complexity found in most commercially 	viable file formats.

I'm having a slight problem with the POV raytracer.  I'm not sure if this is the correct group to post to or not.  I create .tga files on a unix machine using pov.  Then when i download them to display on my pc, they're listed as bad files.  But when I create the file on my pc, it displays fine.  Are unix .tga's incompatible with the pc?  An easy solution to this problem would be a unix targa->gif converter.  Anyone know where I could find one?  Any help on this subject is appreciated.

I hope someone can help me with the following problem - I'm sure there must be a known solution.  Given a rectangle defined by  -X <= x <= X  and -Y <= y <= Y  where X and Y are constant  and a parallelogram defined by  -C1 <= a*x + b*y <= C1  and -C2 <= c*x + d*y <= C2  where C1, C2, a, b, c, d are constants and b/a != d/c (i.e. not parallel lines)                                ^^                                           not equal to  what is the area of their intersection?

At the  moment it looks like I'm going to have to look at all possible cases  and examine each seperately e.g.  1) rectangle encloses parallelogram.   2) parallelogram encloses rectangle.  3) two corners of parallelogram inside rectangle                            ^                          / \                         /   \                        /     \            Y -------------------------------  Y              |       /         \           |              |       \          \          |              |        \     .    \         |       . origin              |         \          \        |              |          \         /        |           -Y ------------------------------- -Y             -X            \     /           X                            \   /                             \ /                              "  4) two corners of parallelogram outside rectangle     I hope someone can help.

If this question is covered elsewhere, I apologize, but I need information fast.  My department has been given a large sum of money to install a video system on our network of IBM RS6000 workstations.  This is not an area in which I have any expertise, so I wonder if anyone out there can offer advice.  We would like a system, based either on VHS or 8mm video which will allow one  write video, frame by frame on tape for play-back in real time.  It's for visualization of physics problems.  Can anyone tell me what hardware is available which would work for our system?  Some support software is obviously needed too, but nothing particularly sophisticated, since the software we actually use for the visualization is all already written.  Please email with replies, as I don't read this group.  Many thanks for your help.

Up until last week, I have been running POVray v1.0 on my 486/33 under DOS5 without any major problems.  Over Easter I increased the memory from 4Meg to 8Meg, and found that POVray reboots the system every time under DOS5.  I had a go at running POVray in a DOS window when running Win3.1 on the same system and it now works fine, even if a lot slower.  I would like to go back to  using POVray directly under DOS, anyone any ideas???  John

Can anyone give me information or lead me to electronic information (not books; I'm too poor...) regarding programming the standard graphics modes? 320x200x4 and 640x200x2 are easy enough, but I'm not so sure about the rest.  Something about planes or something, and writing to ports and the like, but I don't know the numbers or anything -- for the 16 color modes, I think.  If I'm wrong, let me know.  Also, 320x200x256 is just one byte/pixel; that's easy enough, but are there any other ways to write to the screen, perhaps bytes at a time, or something like that?  Of course, I'd appreciate any information about any mode....  which reminds me of another question -- do the SuperVGA modes work the same, generally, as the normal 16 and 256 color modes, or is not only the mode numbers for various cards different, but the methods for writing to the screen different as well?  Thanks for any help you can give me...  I'm developing a screen class for C++ and find myself searching for information.  Oh, I do have Ralf Brown's Interrupt List, which has given me tons of invaluable information already. It just doesn't go into the screen programming details (except for the read/write pixel BIOS calls...  Thanks again.
