In my computer graphics classes at CMU, and here at
I've been doing some interesting 3D graphics work
A few projects dealt with using splines to
construct curves in space, using keyframe animation, and
writing a ray caster. An image or two from the various
projects are below. Also studied were Bezier patches,
Fourier transforms, and more rendering techniques.
At work I've done projects dealing with volume rendering,
real-time physical simulation, and model animation.
And the list grows...
Ever since I bought a Silicon Graphics workstation,
and now particularly with my Linux PC and
GeForce 2 card,
I've been working with the OpenGL
graphics API to work on some pretty interesting projects. I love the simplicity
and speed of OpenGL; very intuitive and straightforward.
My current project, while not doing 3D graphics hacking for dsBOX's
is porting a small subset of the OpenGL API
to the Palm Computing platform. I know, it's crazy. But fun.
Check for status on the miniGL
page over at dsbox.com.

Graphics I project (includes modeler). OpenGL was used. 450x337 JPEG image.
My real interest is in the field of physically-based modeling using
3D real-time computer graphics. I've been doing my work with
SGI's 3D graphics library, and I'm liking it more and more...
In particular, I'm using many of the GLX extensions to your standard
X server to combine OpenGL and the Motif widget set in visualization
applications that run under the X Windowing System.

- miniGL sketch for SIGGRAPH 2000
- code for Bezier splines
For 2D graphics (like the title graphic at the top of this
page) I use the
or GNU Image Manipulation Program,
which was developed by Spencer Kimball and Peter Mattis. It runs
only on UNIX machines running the X Windowing System, and allows
functionality almost on par with Photoshop! That along with
covers everything I need to do to make some pretty interesting graphic
images on my Indy and Linux PC.
