Nasos,
If you're using the default subdivision in the Sphere class,
160M for 2000 spheres with identical appearance is way too much. I did
a quick test program, and here is the result :
Number of Spheres (with subdivision 15) = 2000 spheres .
Total amount of memory taken up :
mem used - before: 10966k after: 10190k
mem used - before: 10190k after: 10191k
mem used - before: 10191k after: 10192k
mem used - before: 10192k after: 10193k
mem used - before: 10194k after: 10190k
mem used - before: 10190k after: 10190k
mem used - before: 10190k after: 10190k
It should be slightly more than 10M. I did nothing special, except
all spheres share the same Appearance object. Also please note all
spheres share the same geometry object.
* By default all primitives with the same parameters share their
* geometry (e.g., you can have 50 shperes in your scene, but the
* geometry is stored only once).
thanks,
