Hello everyone!

I have a question regarding transform3D and transformGroup objects.  Specifically, how 
large are they in bytes, in general?

I would like to know this because I am tying to minimize the memory footprint of my 
application.  My app has lots of repeated geometry, in different places though.  So 
this leaves me with 2 possible optimization approaches (i believe)
1) keep each repeated geometry in its own GeometryArray, and transform it 
appropriately to appear in the world where I would like
2) make only one of the repeated geometry, but in a shared group.  Then add many 
transform groups to my scene, with each transform group having a link to the shared 
group.

So basically, if the transform3D and transformGroup overhead are less than the size of 
my shared geometry, i should do option 2, otherwise i should do option 1.

Any thoughts?  Also, any other proposed options?

Thanks,
Ian Nieves
