arghC Consulting
arghC Consulting is the result of over 30 years of
computer experience and almost 20 years of internet
experience (which doesn't quite explain why this page is
currently a slight modification of what was my home page
from my university days. (No one calls their sites "home
page" anymore...) I have several projects on the go,
including intranet contract work I can't show you and some
personal obsession sites including skate.org, a figure skating
fan site, and The Chinese
Knotting Home Page. This site I
plan to use as a dumping ground for what I've learned and
showcase my computer work for those who are interested...

Our growing family
This page describes my computer graphics
research interests. My consulting, resume, hobbies, and personal information are on different pages.
Disclaimer
My accounts have been moving around quite a bit and everything is
backed up on tape, so my files are not as they should be.
Consequently, a lot of what should be here I'm going to send you to
other people's web pages to find.
Facial Animation
My Masters thesis
work
at the University of
Calgary was on facial
animation with hierarchical
splines and simulated muscles. Hierarchical
B-Splines are the work of David Forsey,
who is a professor at UBC in the
Imager Lab.
A few of the animations
I used to illustrate this work are available as a series of SGI RGB
files. When I get the disk space and the time I will convert them
into mpegs.
Joseph
Provine extended my system to do some speech animation.

Rocks
One of my other obsessions are rocks, crystals and
minerals. I've cobbled together a small program to test some
personal theories on crystal growth/formation and then used Rayshade
to generate a few pictures. These are some of the ones I was most
pleased with:
-
This was one of my first attempts, and is
not actually supposed to be anything in particular.
-
This was my test object to see how much of a difference
the index of refraction made. Whether there would be an actual
visible difference between halite (salt) and ice (there is, cool, eh?
8).
-
Increasing the number of iterations on my program
produced a more complicated object, and since making it transparent
would have taken forever to raytrace, I went for galena 8).
-
While cubes and octahedra are fun, there are many more
shapes to explore. An easy one was spheres and the first mineral that
sprung to mind was hematite (ok, so it's reflection index is too high,
sue me! 8)
-
A picture that I've been working on, off and on since I
started undergrad. If you've read the fine book After Long
Silence (also known as The Enigma Score) by Sherri
S. Tepper
(and if you haven't go do it now!! 8), you might recognize the image.
It is still far from done (trees really should not throw shadows on
the sky 8), but I'll keep ya posted. 8)
