OK, thanks to the ONE person who gave me a reference to a book on how to
do what I want to do.  Unfortunately it's nowhere to be found and the only
thing similar costs $70.  Surely SOMEONE on the 'net can out of the
goodness of their heart HELP me.
 
I want to translate world (x,y,z) coordinates to screen (X,Y) coordinates
based on a viewpoint of (xe,ye,ze), looking in direction (theta, phi). 
Hidden line/surface removal, line clipping, etc. is also needed.
 
PLEASE give me some information.
 
And YES, I will post a summary if I get any information other than another
reference to Foley and VanDamme's book...  (translation: DON'T SEND ME
MAIL ASKING ME FOR HELP.  Last time I got 10 messages asking to send them
info on this, and I didn't get any info)

It is not recommended to install IRIX 4.0 yet; there are a lot of little,
annoying bugs which need to be fixed first. For instance, when compiling
graphics programs on Power Series machines (this problem does not exist
on the Personal Irises) one must link to -lfm_s *before* -lgl_s and -lc_s
or else the compiler comes up with the error: "getcpos: not found". These
sort of annoying errors occur all the time; since they take time to figure
out, it probably is not worth it to install the new operating system.

Dear colleagues,

There exist some software converting SUN-raster format (or other formats

DECstation?

This message relates to the use of AVS 3.0 on a Sparcstation 2.

I find that when using the following network :-

			+----------------------+
			|    read field        |
			+-----------+----------+
			    	    |
			    	    |

		 |				|
		 |				|
	  +----------------+		  +---------------+
	  | graph viewer   |		  | graph viewer  |
    	  +----------------+		  +---------------+

that the output ALWAYS goes to ONE WINDOW ONLY (even tho' two are visible).
If I select and manipulate the "orthogonal slicer" bar using the
left-side menu, I see the left graph viewer box in the network "light up"
briefly as the data flows to it; if, on the other hand, I select and
manipulate the "generate histogram" option, I see the right graph
viewer box light up briefly, but the RESULT IS ALWAYS DISPLAYED IN A
SINGLE WINDOW, the other window always remaining blank (no axes, no
nothing).

I imagine that this must be some sort of X-communication problem perhaps.

Has anyone else running AVS seen this problem on their machine
(regardless of architecture ) ? Any patches known ?

Roddy,

This was a bug in AVS3 and has been fixed in the AVS4 release. 

BTW: AVS4 is now shipping on the SGI and SUN and is in final release stages 
for the other workstations!

I have been working with AVS and writing modules for two years now,
and have been doing some group research recently that has involved
writing a module in C++.  Maybe I am behind on the latest, but
the AVS developer's header files do some nasty things (stuff that
one would think they would have had the foresight to avoid), such
as using the words 'class' and 'template' as identifyers.
	Also, many of the frequently used functions have no forward
declarations (I grep'ed the entire /usr/include/avs directory).  We
have fixed the class and template problems with the following;

#define template avs_template
#define class avs_class

(Include avs headers)

#undef class
#undef template

The other problems have been fixed by creating our own AVS header file
with forward declarations of the undeclared AVS functions.  Of course,
the use of the 'extern "C" {}' system is also neccessary, but that is
always true when mixing C and C++.
	My question is;  Is anyone out there doing any AVS in C++?  Am
I reinventing the wheel, or has no one ever tried writing modules in C++?
If someone has done it before, I would love hints.  If no one has done
it before, I should probably be compiling a list of neccessary changes
to link the two.

Hey Jim,

The directory /usr/avs/filter contains the source to make two
programs: geom_to_text and text_to_geom.  These convert the native

A while ago I asked for info regarding the AST TurboVision

as I got no reply. But I cannot believe that this actually true.
So I decided to give it a second try. 

I have a AST TurboVision graphics card and monitor. I bought this
combination at an auction. The AST TurboVision graphics card has
a TMS34010 on board; the monitor seems to be a fairly high
resolution monochroom A4 monitor.  Nice hardware, but not very
usable without software or documentation. 

Is there anybody with technical information about the AST
TurboVision card and monitor? Who has a driver for this card? 

I would appreciate it very much if somebody could give the
info I need or can point me to the right source.

I have heard about so called Ray Tracing. The name implies that the
