BioVision Hierarchy (BVH) is a file format used for storing motion capture data. It was developed byBioVision, a company that was later acquired byMotion Analysis Corporation. The format consists of ahierarchical structure of joints, with each joint containing rotation and translation data. BVH files are widely used in the film, gaming, and animation industries.
BVH file format's history and development span back to the 1990s, and it was originally developed as a proprietary file format for BioVision's motion capture systems, but later it was adopted by other motion capture systems, such as Vicon and OptiTrack. In the early days, BVH files were created for specific models and needed to be reworked for different models. However, as the use of BVH grew, more standardized models were created and used across different systems.
The development of BVH file format was a significant milestone in3D animation and motion capture. Prior to BVH, motion data was recorded with pen and paper or entered manually into a computer. BVH allowed for the automatic capture and recording of motion data, making it easier and more efficient to create realistic animations.
Today, BVH remains a widely used file format for motion capture data and is supported by many animation software packages, such as Autodesk's Maya andBlender. It has become an essential tool in the animation industry, particularly for creating realistic and lifelike animations for movies and video games.
