The Biovision Hierarchy (BVH) character animation file format was developed by Biovision, a defunct motion capture services company, to give motion capture data to customers. This format largely displaced an earlier format Biovision providing skeleton hierarchy information as well as motion data.
As of 2008, BVH is widely used, however not all applications support importing and exporting files in this format.
Examples of software using files in BVH format:
