The numbers next to the OFFSET Keyword is the relative position of node from its parent node when the parent node is unrotated.

Yes the BVH file contains the angles of the joints. As you parse the HIERARCHY, in a linear fashion you will come across CHANNELS, you need to remember the order in which you found the channels as those streams of numbers at the bottom of the file are in the same order. Each line of those numbers is a Keyframe.

Did you use [google]?

I found this on the first page when I googled for "BVH file spec", and it appears to have at least some of your answers.

Edit:: ColmMac got in first, but my link works. [smile]
