...I totally agree, to the point of already having started:  this was  
the idea behind the "shapesynth" I presented at the first pd-conv 2k4:

http://puredata.org/community/projects/convention04/lectures/tk-tittle/

...since this was done before the new list features of pd 0.39+, it  
needs to be updated (and I don't know how many times I've said I'd  
commit it to the sf.net abstractions...)  Also, there was a bug with  
the 3dmouse abstraction, where nothing would be displayed after  
"start rendering" until there was a mouse click in the window...

...just a coupla days ago I started to merge the long dormant  
vertex_array code that was started by cgc, and enhanced by  
IOhannes' [vertex_tabread] comparatively recently...currently  
extremely undocumented, but at least my effort's currently directed  
there atm ;-)  I'll send an example patch later today:  got a few  
meetings in a bit...
