[ODE] XML ODE Data Interchange Format (revision 5)

[Jon Watte]

If you want to support model space conversion, you'd have to also support changing winding orders, and supporting negating values (because swapping components takes left-handed data into right-handed, and vice versa). At that point, I think we're beyond simple data representation and squarely inside data processing, which probably is overkill.

Cheers,

Another nice aspect of being able to specify the format is if you are 
porting data from one application to another where the world has been 
set up differently. For instance if the data you have is defined with 
the z axis as up, whereas yours has the y axis as up.
We get this all the time when importing stuff from 3DSMAX. Instead of 
having to reformat the whole file, you could just change the format to 
"x,z,y". Similarly if you wanted to convert row major to column major 
matrices or vice-versa you could just change the format attribute. It 
may also open up the format to graphics as you could add color, alpha, 
texture co-ords, etc.. You could also make the format attribute 
optional, so that <vertices> assumes a format "x,y,z" unless you specify 
otherwise - or would this confuse things?
