Converting BVH information into POVRay animations
=================================================

I used the Heirarchy information from the bvh file to derive
the default positions of the body parts.

I then took the Motion information and editied it so that it 
can be read directly from POVRay. The editing required is:-

	Remove all the text, leaving just a list of numbers

	Replace all the TAB characters with commas

The data for the BVH channels are read into POV variables,
and these variables are used to position the body parts for
each frame.

One subtlety is that, as in this case, the BVH can specify the
rotation channels in the order Z,X,Y you can't just perform
a "rotate <X,Y,Z>" in POV. Rotations aren't commutative. What
I had to do was perform "rotate <0,0,Z> rotate <X,Y,0>" which
performs the operations in the required Z,X,Y order. If you
are converting a BVH file that has the channels in a different
order then you may need to do this differently.


Grenade.pov	is the POV code
Grenade.bvh	is the original BVH file
Grenade.txt	is the data extracted from the BVH file
		which is read by POV.

Set "final_frame = 177"
