The PyODE Ragdoll Tutorial has received a
fix to a bug that previously prevented collisions from being detected when run
on some versions of Python.
A research paper I originally wrote 7 years ago entitled Nearest-Neighbor Approximation Trees for Fast Surface
Registration has been posted. This paper has been sitting on my hard drive
following a dead end in my early graduate work. Possibly interesting to anyone
who develops software to combine separate digital scans of 3D objects into a
single pointcloud and surface mesh.
DupeFinder 1.1.0 is
available. This version removes the need for an external md5sum command line
utility. This improves performance calculating MD5 digests for small files and
eliminates a cumbersome dependency for Windows users.
Initial release of Color
Machine 0.8. Color Machine is a palette shifting
screensaver. At least, it's almost a screensaver, it can't actually start
automatically. It's still nice to look at though. Why version 0.8 for an initial
release? I actually started working on this in high school, and ported it from
DOS partially to OpenGL, and finally to SDL. Though a bit incomplete, this
project is fairly mature.
PyODE Ragdoll Tutorial posted. I created
this tutorial after needing to make my own ragdoll simulation using ODE and not
finding any good tutorials on the web. This tutorial is meant to provide a
useful and practical codebase in addition to being informative, and hopefully it
will help you game programmers out there add a touch of realistic physics to
your own projects. Source code
directly available here.
SnapMatcher 0.4 now available.
This version adds the ability to quickly identify matches between an existing
image database and a small set of external images. It also corrects the flawed
bugfix in version 0.3 for allowing image databases to be created on Windows.
SnapMatcher 0.3 now available.
This version adds features allowing efficient updates and match identifications
to existing image databases, as well as a bugfix to allow image databases to be
correctly generated on Windows.
SnapMatcher 0.2 now available.
Improvements in this version primarily concern performance: 30%-40% faster image
database creation, and smaller file sizes for both the database and match
results. Also includes minor command line interface changes and a large number
of basic code improvements and cleanup.
Initial release of SnapMatcher
0.1. SnapMatcher identifies matching and nearly
matching images in large collections. Matches can be found even between images
that have been modified using techniques such as rescaling; brightness,
contrast, and color balance adjustment; the addition of text and borders; and
even minor cropping.

A research paper originally written in 2003. It describes using a special form

partially overlapping surfaces, used in reconstruction of 3D models from
separate, partial surfaces.
