Scott King has installed the latest version of the OpenGL software 
port Mesa (v.2.5) in the /n/0/shape/graphics/Mesa-2.5 directory. The 
WWW page from Mesa is in /usr/class/cis681/crawfis/OpenGL/Mesa.html 
which has many other useful links. There a several sample programs in 
Mesa-2.5/book Mesa-2.5/demos and Mesa-2.5/gdemos

povray in /usr/contrib has been upgraded to the latest version (3.02).  


POV (persistence of vision) is a fast (in the sense of faster than other 
ray tracers), supported, public domain ray tracer, which is widely used to 
create high quality ray traced images.
See http::/www.pov.org/ for more details.

 Here are the changes between public POV-Ray 3.00 and 3.01.

 1) Fixed problem with some dda errors in height fields

 2) Fixed error line number bug.  Comments with // got double counted.

 3) Fixed problems with file input from stdin and file output to stdout.

 4) Fixed problem with PNG image maps.

 5) Fixed problem with illegal keywords in a # directive

 6) Fixed problem with smooth triangles that only bend in one direction.

 7) Fixed some blob bugs

 8) Fixed some lathe bugs; Modified lathe intersection code (much faster
    now); Modified sor intersection code (much faster if sturm is used)
    Fixed another bug in POLYSOLV.C

 9) Fixed problem with backslash in string literals

10) Added experimental feature warning to halo, atmosphere, and radiosity.

11) Fixed problem which split a file if you changed directory while
    rendering.

12) Fixed 'declare' with no '#' bug and added warning

13) Eliminated unnecessary light buffer on shadowless light source

14) Fixed TTF Normal bug
    Applied patches to TTF code to fix visible tearing
    Also added a check to allow Mac TT fonts to be used 
 
15) Fixed empty texture bug

16) Fixed problems with deeply nested #while, #if, #switch etc.

MSDOS:Fixed true color Diamond 24X
      Fixed djgpp make file
      Fixed problems with +FS output creating corrupt targas.

XWINDOWS: Changed colormap handling to dynamically allocate colors.

Linux SVGA: Added grayscale palette for preview, fixed video mode
      selection.

UNIX: Fixed up prototypes and variable types to remove many compiler
      warnings.
      Fixed problem with interrupt handler when writing to a broken pipe.
      Fixed problem with dithering code for mosaic preview.

You have an option to use the POVRAY program for extra credit 
for the final lab excercise.  The most recent version is located in
the following dir:

/usr/contrib/src/povray/3.02/povray3

there are many demo programs there.  Everything should be there.  There
is also a version of the povray Exe in the /usr/contrib/ directory.  I 
usually use this one and it works fine.

What I want is a basic scene composed using povray.  You can MODIFY one
of the sample programs and add a few basic items like spheres.. cones, etc..
The bonus points will be awarded based upon the complexity of the picture!

For this extra credit you need to supply the *.pov files AND a script of
some sort that will generate the pictures.  If I have to manually render
them you will not get credit.  Also specify the size of the image to be
small.  150 x 150 pixels is fine for grading.  Also DO not use the 
Anti-Alias option for this causes a time strain.

On Line documentation can be found at 

www.povray.org

Please do not ask me any questions about specifics. The goal of this
excercise is for you to find out about it on your own and create nice
pictures.

good luck

Jason Lescalleet, a student in my 782 class, graciously volunteered 
to port and install the GIMP software package. This is an X-windows 
Photoshop-like painting and image manipulation package. Now you can 
truly waste time as you try your hand at digital painting. See 
Jason's note below on the current location of the software and 
various disclaimers. I will try to find a good permanent home for the 
software (shape/graphics? or usr/contrib?) at a later date and move 
it over to that location. I will post another announcement when I do 
this.

Check out:   http://www.gimp.org  for more details. Also, look at the 
net-fu link for a cool way to create logo's using GIMp and Java.

Thanks again Jason!!
Roger

Well, after several failed attempts to compile and install GIMP, I 
think I've
finally succeeded.  If you want to give the program a try, the 
command is

/usr/class/cis782/crawfis/GIMP/bin/gimp

Like any free software, it has its bugs (word to the wise, don't try 
to
convert an RGB image to indexed color using an optimized palette) and 
for
some reason the scheme scripts don't load properly, but it's still a 
pretty
good program.
