Bvh树 python
WebBVH parser This is a simple parser for BVH (BioVision Hierarchy) character animation file format. It converts the original BVH file to a more readable CSV file to see the frame angle and position data of a joint more clearly on a spreadsheet. An example motion capture file in BVH format is included in the repo for testing.
