Hi Robert

I am so sorry. In my appliction, I can load a lot of ive models 
dynamically. When i load about 120 ive models, the memory usage is about 2.5G, 
and the frame rate about 25-35. Now I want to minimize  the memory usage to 
optimize my application because the camra can't see all objects. Now i don't 
know how to begin.
I don't know whether you understand. Thank you for your reading and answer.

Jhon.

Re: [osg-users] Multiples scenes

[Florian GOLESTIN]

Hi Robert

I gave a look to the osg::Switch and it's interesting too!

I don't need to mix the two scenes, in addition I need to restore the position 
and the animation of the monsters. 
So I've opted for the "viewer.setSceneData(newModel);".
It works well so far!

Thanks for your answer!

Florian
