# character-animation-1: Character animation with Cal3D : here comes Balazar the Sorcerer !

22
# Or how to write a Cal3D viewer in less that 20 lines...

24
# For information, this character has been created in Blender and exported to Cal3D
25
# with my Blender2Cal3D script: http://oomadness.nekeme.net/en/blender2cal3d/index.html

# See Cal3D documentation for more info, and Cal3dShape and Cal3dVolume docstrings for
28
