Nothing about vertex arrays is set at this point.  Right now it's just 
a collection of objects on my HD that I'm trying to make into a 
coherent set of tools for 'dynamic geometry'.  The current idea is to 
have a set of vertex generators like a grid or a .obj model loader and 
a set of vertex manipulators for color, position and so on.  The idea 
is to process vertex, color, normal and texture coordinate data just 
like pixels or audio.  Pd/GEM is not a very effective environment for 
representing large data sets to the user, so very fine editing of the 
data might not be all that possible.  The goal is to have a way to 
algorithmically alter geometry over time - think about something like 
newwave or Cyrille's pmpd applied any model you load into GEM and you 
start to get the idea.  There will probably be lots and lots of of 
problems to solve before these objects become all that useful.

By all means let us know what you find lacking about GEM.  The past 
year has been spent getting 'the basics' on each platform up to par and 
improving performance and stability.  Now it's time to get some really 
interesting things going.
