Hi,
    I am looking for images that I can redistribute of Pearls, Clams,
Oysters etc. I can take the image in several formats PICT, TIFF, JPEG,
GIF etc. The images will be used on a Mac. as part of a project. I can
manipulate anything up to 24 bits. The images can be of any type (ray
traced, scanned or drawn/painted).

	If anybody has the CPU time, ideally the image will be of an Oyster
(half open) with a large pearl in it ray traced to 24bits deep
(reflection off the pearl etc) ;-).

	If you have a relevent image or can point me in the right direction I
will be grateful.

Thanks,

Hi,

I am currently evaluating CGM as an intermediate graphics format to be used to send 
data to different hardcopy plotters.  The thought here is to create a procedural interface
for my applications to write CGM data.  This data would be sent to a plot engine for
conversion into the plotter specific formats. (HP-GL, PostScript etc).  In looking at
CGM there are a few problem areas that are not addressed.

  * Dithered color specifications
  * User definable line styles
  * Resolution 16 vs. 32 bit coordinates
  * No relative coordinate capability
  * No view port capability
  * How do I know I am producing and reading correct CGM?

How is CGM being accepted as a standard?  
Is the document Sections 5-8 ready yet?
Should I be looking at a different "standard" format?
Are there any good writers and readers available? (pay or free)

Any thoughts on the subject?

so that it can fit the angle of viewpoint.
I knew that if I use transform from 2D map to 3D, it may leave some

any idea about this, or you can give a greatly hand if you know where I

Hi,

I am looking for some software(freeware or payware) on Hidden Line Elimination,
to handle a large volume of data about (50000 primitives). I shall also 
appreciate if I could get some pointers to recent developments and alogorithms
in this area to handle such data.
  
  To elaborate, this is my situation:

  1). I have all of my primitives (all are polyhedrons) in the form of
      full_winged_edge_data_structures (Lincloln_face_models). In other
      words I have all the connectivity information such as edge-to-edge,
      edge-to-face, edge-to-vertex, vertex-to-vertex, vertex-to-face, 
      face-to-face and vice_versa, and also the normals of each bounding 
      face and so on. Like by this connectivity for example, given an edge
      I can yank out its end_points, the edges shared by these two end_points
      and the two faces that this edge seperates and the edges that bound these
      two faces and so on.

  2). Also the volume of data that I have to handle is very large, like to
      the extent of about 30,000 - 50,000 polyhedrons.

	Since I have so much of the geometrical and topological information
      at hand I was wondering if there is any alogrithm out there which
      making use of the available information reduce further computation
      to the least.
	Any algorithm or idea that you may have would help me, atleast in
	developing one of my own.

	If u had developed/involved in a hidden line elimination for vast
	data your comments and advice shall be well appreciated.

			Thanks in advance.

Meanwhile, we're using Panasonic S-VHS recorders with a "Mini-VAS"
controller.  Works pretty well, except that the Mini-VAS uses a
non-standard time code, so if you then want to edit with something
like a Digital F/X you have to make a copy with the correct striping,
so you get an extra generation.  Unfortunately, the Digital F/X (at
least the last time I used it) doesn't really support single-framing.

You also need a sync generator and other assorted equipment.
Questions on our setup can be directed to Mike Niel

I am new to computer graphics and I just learned about SunPhigs(1.3) 
by myself and wrote a simple program to display and move a robotic arm 
on the screen. However it doesn't work: the program just opens a 
blank window. I don't have a clue why it doesn't work and I would 
really appreciate if you could suggest any possible reason where the 
problem is. Here is a summary of my program structure and the problem:


PROGRAM STRUCTURE:

There are seven structures and they execute each other with EXECUTE 
STRUCTURE elements.
After the structures are defined and the root structure posted, 
the structures are edited in a loop in which the structures are
opened and edited one at a time.
The only editing that is done is replacing the LOCAL TRANSFORMATION 
element after calculating a rotation or a translation matrix which is 
passed as a parameter to SET LOCAL TRANSFORMATION. The modification and 
deferral mode used is NIVE and WAIT and the structures are redrawn at 
the end of the loop with REDRAW ALL STRUCTURES. The values for evaluating
the rotation and translation matrices are read from tables.


PROBLEM:

All the structures except one have the following problem:
when they are edited they don't seem to be able to exectute the structure
they are supposed to execute. The one structure that can still execute 
it's subsequent structure is EXACTLY identical to two others except for 
its name id.

In article <1992Aug26.202245.18060@koko.csustan.edu> on Wed, 26 Aug 92
20:22:45 GMT, rsc@altair.csustan.edu (Steve Cunningham) solicits member
response on the future of SIGGRAPH membership benefits and
publications.

Why is ACM preventing conferences from subsidizing the group?  Other
professional societies operate that way.  Does this mean that SIGGRAPH
registration will get cheaper, or that ACM will snatch the surplus?  At
least in the past, ACM has not been set up to handle large successful
SIGs, such as SIGGRAPH.  There was one year when the SIGGRAPH
conference was $1M more successful than anticipated, and ACM insisted
that the extra money go to ACM and not to the SIG.  The rationale was
that a policy had been set forcing SIGs to live within their budgets.
This was a policy designed for small, marginal SIGs, not for SIGGRAPH.
It was SIGGRAPH's tough luck that they hadn't budgeted for the
unexpected popularity of the conference.  I forget whether ACM finally
got the extra conference money.

If we're going to think about semi-major changes, let's go all the
way.  Should we stay part of ACM?  What do we get from them?  Obviously
if the SIG left, they would keep all the legal forms, such as the
conference name.  However a shell w/o the people is dead.  This
question has been considered in the past, and the decision was to
stay.  However if ACM is changing its rules, it's time to reconsider.

Actually, in order to discuss this intelligently, we need more
information.  Are ACM and SIGGRAPH budgets and minutes available
online?  Are any attendees at the board meetings willing to talk about
anything that might have happened that didn't get into the official
minutes?  What about historical financial trends?

Finally, if conferences are being hit so hard by the recession, why are
2 new conferences being considered?  Should they not be minisymposia
within SIGGRAPH?  That way people who are tangentially interested could
sample them.  Or is the intention to keep the new conferences small and
inaccessible by the masses (not necessarily a bad idea :-))?

Thanks for inviting public comments.
