- <h1>.bf - bone forests</h1>
- <hr>
- <p>
- A .bf file contains a bone forest. That is possibly multiple bone trees, or
- skeletons. Singleton trees will be interpreted as point handles. Otherwise
- each edge in a tree will be interpreted as a bone segment.
- </p>
- <p>
- Each line contains data about a vertex (joint) of a bone tree:
- </p>
- <pre><code>[weight index] [parent index] [x] [y] [z] [undocument optional data]</code></pre>
- <p>
- Indices begin with 0. The weight index is -1 if the bone does not have an
- associated weight. The parent index is -1 for root nodes.
