Vpic won't work with diamon24.cfg on the 24X because that config file
is for the regular speedstar 24, which is Tseng ET4000 based.  The
24X is based on the Western Digital 9031 graphics accerator chip.
It is backward compatible with the Paradise (made by WD) SVGA, so
you can tell vpic it's a Paradise.  You'll be limited to the Paradise's
capabilities (no true/hicolor, no 256 color modes above 640x480).

If you want to look at 24bit targa files, run windows with the 24bit
or 32K drivers and use either the Halo Imager program that came with
the board (it can import targas, check the file menu) or one of the
windows jpeg/targa viewers.

I have updated my dos gif viewer, SGIF, to support the 24X's 256 color 
modes (including 800x600 and 1024x768).  I will add 32K and 16.8 mil.
support as soon as I get the databook for the 24X, as well as targa
and possibly jpeg support.  SGIF v1.7 is on the simtel archive 
(192.88.110.20) in the gif directory.  It is free.

I hear there are several in the works right now, but one is 
available right now. 

(Trying to pull this out of a foggy memory): 
The title is Autocad: 3D Design and Presentation. You may have
seen other ACad books like it - it's the blue and gold series.
I can only recall one of the author's names right now...
Bousquet, but I can get the full info. for you if you like.

The 3DStudio section is good, about 150 pages. It's hardly
what you'd call a "manual." It doesn't go into the shaper
or lofter much at all, but it does have some nice tips and 
tricks for creating certain effects (shafts of light, etc.) 
and outlines how many functions are used (morphing, creating 
your own maps, etc.) It's illustrated and full of step-by-
step examples.

Idraw (like all x applications) uses the 'X Logical Font Description' for
specification of screen fonts.  Using this specification one includes enough
information for the X server to locate a font.  To get a list of the
available fonts from a given server use the 'xlsfont' command.  So to
determine a specification for the Adobe Symbol one might use the following:

  % xlsfonts | grep -i symbol

  -adobe-symbol-medium-r-normal--10-100-75-75-p-61-adobe-fontspecific
  -adobe-symbol-medium-r-normal--11-80-100-100-p-61-adobe-fontspecific
  -adobe-symbol-medium-r-normal--12-120-75-75-p-74-adobe-fontspecific
  -adobe-symbol-medium-r-normal--14-100-100-100-p-85-adobe-fontspecific
  -adobe-symbol-medium-r-normal--14-140-75-75-p-85-adobe-fontspecific
  -adobe-symbol-medium-r-normal--17-120-100-100-p-95-adobe-fontspecific
  -adobe-symbol-medium-r-normal--18-180-75-75-p-107-adobe-fontspecific
  -adobe-symbol-medium-r-normal--20-140-100-100-p-107-adobe-fontspecific
  -adobe-symbol-medium-r-normal--24-240-75-75-p-142-adobe-fontspecific
  -adobe-symbol-medium-r-normal--25-180-100-100-p-142-adobe-fontspecific
  -adobe-symbol-medium-r-normal--34-240-100-100-p-191-adobe-fontspecific
  -adobe-symbol-medium-r-normal--8-80-75-75-p-51-adobe-fontspecific

Each of the above specifies a specific X11 screen font.  As much of the
information is common, a simpler specification will still result in precise
match.  For example, '*-symbol-medium-*-240-*' uniquely identifies a font.
If the given pattern does not uniquely identify a font, the first available
font, as listed by the xlsfonts program, is used.

In addition, idraw requires that one specify a postscript font and point
size to associate with the screen font.

Adding the following to your X11 defaults (or resources) will enable for
symbol font items in idraw.

idraw*font12:         *-symbol-medium-r-*-100-*      Symbol             10
idraw*font13:         *-symbol-medium-r-*-120-*      Symbol             12
idraw*font14:         *-symbol-medium-r-*-140-*      Symbol             14
idraw*font15:         *-symbol-medium-r-*-240-*      Symbol             24

It has most of Photoshop's functionality, including soft-edges, editable

Date: Fri, 14 Aug 1992 21:31:01 GMT

I'm trying my hand at rendering some pictures using the radiosity
method.  I've got to the point where each polygon in the scene is
divided up into patches, and I have a color/brightness calculated
for each patch.

I initially rendered the scene without any smoothing, and got, as
expected, a "patchy" scene -- I could see the patches that each
polygon had been divided up into.  Up until this point, it works
just fine.  The problem arises when I try to smooth the scene to
get rid of the patchiness and make it look more realistic.

My question is, what's a good way to smooth these patches out?
Since for each patch there are 8 surrounding patches, it's hard
to come up with a good color/brightness value for a particular
point on the patch.

Hope somebody understood that...thanks in advance,

Try the last chapter of 

Watt, Alan 'Fundementals of Three Dimensional Computer Graphics',
Addison-Wesley, 1989

which is titled 'Colour science and computer graphics'. This is a
pretty good basic introduction which avids masses of detail.

The rest of the book is pretty good, too, BTW

No it's Latin-753BC. It says: Put the subject in your kill file (it's supposed
to, anyway).

Basically, the FAQ war doesn't belong in c.g, but it does need to be discussed
for the group's improved future. If readers do not want to read the junk, put
the subject (and the spawned subjects) in your kill files. If you don't have
kill files...

It's the only thing I have been reading since the remaining articles are FAQs
or uninteresting (to me) subjects.

I probably shouldn't be doing this, as this info is probably in the

I have two questions:

	- Is there a standard algorithm for checking whether
		a 2D polygon is clockwise?

	- Is there a simple way of subdividing a 2D polygon with 
		holes into convex pieces?  (Where the holes are
		2D polygons that are wholly contained in the 
		polygon that delineates the exterior boundary.)

I believe that the first question was asked and answered a few
months ago in this group, but I didn't need the information at
that time, so I didn't keep it.  I suspect that the second question
is also a problem that many people face.  

Perhaps these are good candidates for inclusion in the FAQ(s).

I'm trying to avoid duplicating work that others have done.
Any references or hints would be greatly appreciated.  Thanks.

from the acad r 10 manual:

There is also a binary version of the "dxf" file that they call dxb. 
It should be a little faster to parse.

So if you really want to find out what is in the file youll have to find
a copy of Acad that can read the version of the .dwg file you have.

Sorry if this a FAQ, but I'm looking for a public domain program (on

I do need, however, is a program that can accept non-uniform grids.

I've tried the program Contour (ktoh@mascot.berkeley.edu), yet this
is only for uniform grids.  I've also tried a program called graph and
plot (by S. Narasimhan) (for X-windows),
 but I seem to have some problems running it on my machine.  I was
wondering if anyone knew of other general purpose contour plotting
programs.  

The best solution would be to get a program like SURFER, written

Thanks in advance.
