[Sandy] Objects "faces" vs. quality-dependent number of polygons

[bruce@zeusprod.com]

A recent discussion made me realize that Sandy doesn't have a concept of 
"the number of faces on an object primitive". Instead, the number of "faces" 
is the total number of polygons. 

For example, in a tri mode box with quality 1, there are twelve poly-faces 
(two for each of the six "object faces" of a cube). 

And if the quality is set to 2 (again with tri mode rendering), there are 
now 48 poly-faces (8 for each of the six "object faces" of a cube). 


Is this the way it is handled in most 3D software? 

I think when people want to handle, say, rollovers for a cube face, they 
want to deal with the six faces of a real-world cube, not the numerous 
polygon faces caused by increasing the quality. 


This is particularly relevant for cubes. Probably less relevant for other 
object types. 


I welcome your thoughts.
