[osg-users] Basic memory usage question

[Robert Balfour]

I have a large .FLT model with lots of .tif textures (I actually
converted it offline to an ive with compressed textures).  When it
initially loads it looks like it takes up about 800MB of memory. Then
when it renders (after I zoom into its LOD range) the memory usage jumps
to approx 1.6GB (i.e. it doubles) - I'm assuming this is due to the OGL
display lists being generated/compiled.

After the display lists are generated, is there a way to release all the
original texture images so memory usage doesn't stay doubled, or do they
need to be kept around?

Or is the only way to reduce the memory usage is to go to a PagedLOD
scheme?

Thanks.


Bob.
