Help files for bvhacker, the free bvh tweaking / viewing tool.
bvhacker is designed to give full control over every aspect of a bvh file. bvhacker is not intended to be used to create bvh animations - there are a selection of packages out there already, both free and commercial. bvhacker was created as a tool for converting existing bvh files into a format usable by games like Second Life. Since it's creation, bvhacker has evolved into a tool ideally suited to preparing animations for uploading into Second Life.
Bvh files created using motion capture data can be found all over the web. I recommend Animazoo because the files there are free to use without legal obligation. Producing animations using real motion capture data can make the final results look far more natural than those produced using artificially generated motion data.
If you do sell animations made with bvhacker you have an obligation to obtain permission from the original bvh motion file creator to re-sell their work.
This does not apply to files from Animazoo - if you want to re-sell animations from there you are permitted to do so as long as you add the words 'Animazoo' to the name of the animation when you put it up for sale.
