You can peruse my resume. Please bear
in mind that I'm not promoting myself as a web designer.
My search engine of first resort is Google:
In my copious spare time (i.e. I haven't worked on this for two
years), I'm developing a visualization tool for playing with various
geometric forms. Some features:
My goal with this project is to simulate things like hot air balloons,
vacuum baloons, and ultimately a practical solar-powered dirigible
partial-vacuum aerostat. Here are some screenshots of my progress so far.
I would very much welcome correspondence from anybody with an interest
in these matters.
- OpenGL graphics which are getting faster and prettier
- Tools for generating a large subset of 2D simplicial complexes:
- geodesic spheres
- geodesic toruses
- crystal lattices
- A simple but careful physics engine
- damped springs
- viscous medium
- pressurized gas (ideal, adiabatic, parameterized gamma)
- careful attention to energy transfer and conservation
Also, as a nod to academic honesty, here is the
source code which generated those images.
I'm compiling on Red Hat 9.0 which includes XFree86 4.3.0-2 and the
Mesa 5.0.1 implementation of OpenGL 1.3. I have machine which was fast two
years ago, a 833Mhz Pentium-something-or-other, 133Mhz bus, 768 MB RAM.
This code is still in the experimental-brainstorming state. Pre-alpha. It is
undocumented and has poor error handling mechanisms. The bibliography is far
from complete. Nevertheless, I'm posting this snapshot as documentation of
More recently, I tried to get this same code package to run under
X/Cygwin. Happily, it ran perfectly without a single char of source
code edits. I did have to change the path to the OpenGL libraries in
the Makefile, but I didn't touch anything else. Let that stand as an
awed testament to the beauty of Cygwin, without which the last two
years of Windows work would have been much less productive and no fun
A couple of pictures of me. I don't live in Tasmania, I just visited there
recently and my Dad, Brock, took a bunch of pictures.
