# This is a custom Blender export script to output an object to a format that's easy to use in
# android. While open gl allows the use of an index buffer for vertices, the same cannot be done
# for texture coordinates, which is why this script duplicates the vertices and normals. This
# gives a larger but faster loading file, hence the tongue-in-cheek name "Compressed" object file.
# The format is number of vertices + list of vertices (3 coord, 3 normal, 2 texcoord)
