The Document Transformed

Masterclass with Adva Zakai (Thursday) and presentation (Saturday) on the BioVision Hierarchy file format.

BioVision Hierarchy (.bvh) is an ASCII file format used to import data from various motion capture systems into 3D-animation software. It was developed in the mid-nineties and remains one of the most commonly used file-formats for transposing movement captured in physical space, to a computational environment. Around this relatively legible format, a rich ecology of software tools developed. The file-format functions as a boundary object between practices and bodies, as it is used by animators, game developers, interface researchers, medical professionals, dance-historians, sports-analysts and engineers.

Together we will analyse the .bvh specifications and samples of the file format in order to understand what imaginaries of the body are encoded into it, what a bipedal skeleton hierarchy consists of, and how rotational data for rigid bodies might constitute a movement in itself.

The reading of the .bvh file format is developed with Adva Zakai in the context of Possible Bodies, a collaborative research initiated by Jara Rocha and Femke Snelting on the very concrete and at the same time complex and fictional entities that “bodies” are, and the matter-cultural conditions of possibility that render them present.
