Ah! yes. Economy of means.  That is true.  Firstly because the manual 
element is removed and then also because the paradigm is of replication 
through model building. If you leave detail out of the model it doesn't 
seem like a "suggestion" to the viewer, it just seems like a crude 
model.  The exceptions make for an interesting side discussion though*. 
    I think one place these concepts come into play is in texturing and 
expecially with texturing * resolution.  The pixel plays a role in 
whether the texture can suggested, or handled more explicitly.  Also I 
suppose, in how much detail is necessary in a model.


*Just to get it said, in mesh modelling there is a strong tendency to 
economy of means, further bolstered by the psuedo-pragmatic ideal of 
models animating well.  And notice that in mesh modelling the manual 
role is restored to a degree.
