BVHFiles.jl is a package for working with BioVisionHierarchy files, a file format which stores motion capture data in a hierarchical structure. 

BVHFiles.jl uses [graphs](https://github.com/JuliaGraphs/LightGraphs.jl) to represent and manipulate the data.

## Installation

The package is registered and can be installed using the package manager.

In the Julia REPL type `]` to enter the package manager REPL mode and run

```

pkg> add BVHFiles

```

## Examples

Here a BVH file generated by [alaska/Dynamicus](https://www.ifm-chemnitz.de/produkte/mensch-technik-interaktion/alaskadynamicus/) (green) is transformed in such a way, that the 

movement can be transfered to a file [DAZ3D](https://www.daz3d.com/) can handle (red).
