Image Description, by
Hey flipcoders! This screenshot shows some features
of my Galaxy3 project. More info is available at
http://www.cbloom.com/3d/galaxy3screens/index.html
The top two images show the bunny and fandisk models
at full detail. The bottom two images are wireframe
versions of the shots above them. The left two
horses are full detail (64k tris) and the right two
horses are low detail (1500 tris).
The models are standard research models. They were
automatically uv-mapped by Galaxy, a normal map
was generated, and then they were simplified. No
manual tweaking or adjustments of the models were
made.
They are lit using a simple cube-map lookup. The
lighting model is basically just CubeMap[Normal]
per-pixel. The cube map is only 8x8 on each face,
and is generated on the CPU by sampling the local
lighting environment.
The automatic uv-mapper is the most exciting piece.
It's an implementation of LSCM by Bruno Levy, with
some modifications. You can get more info on LSCM
at http://www.loria.fr/~levy/
The tech in Galaxy3 is fully functional, but it needs
more cleanup and UI work that I just never seem to
find the time for. Contact me for more information.
