dotX format

Now, I think new format of 3d shape data.

And I study other application's data formats.
First, I study dotX, is format of softimage|XSI.

dotX is perfect for 3dcg data, has not only shape data but also animation , bone and so on.

Shape data in dotX is named SI_Mesh, It involves volume and face group.
In addition, It has triangle strips.
