They involve knowing the size of the object, but thy know it themselves. A 
simple case:

int * a = new int[variable];
[...]
delete [] a;

In such case delete [] doesn't need to be told how large the array is, it 
knows it itself.

Anyway calling delete on dxGeom* will work just as on dxSphere* as long as 
dxSphere doesn't have its own (non-virtual) destructor.
