    Some formats have object-space vertices and a bind-pose skeleton that's used to transform them to bone space. MD5 appears to have the vertices already in bone space, and a bind-pose skeleton for...

    The only vertex positions in the file are in joint space; if you ignore the joints, you'll typically get garbage.

    Note: most of what follows is based upon what's written here.

    The skeleton in an md5mesh file is the bind pose skeleton. This is used to transform each vertex from a list of joint-relative...

    The root bone is just the root of the transformation hierarchy. As all transformations are relative to their parent, moving or rotating the bone moves or rotates the entire model.

    The point is the position of the joint in the parent's coordinate system; the quaternion is the rotation of that joint. Between them, they specify the transformation for that joint relative to the...
