[osg-users] Updating scene properties instead of recreating it each frame

[Igor Spiridonov]

Hi dieslower81.

I don't think clearing vector is a problem since it's capacity prevents deallocation/allocation.

I can't just update values since i receive polygons with different number of points. I can try to find a geometry with particular number of points but this approach is not general and i'm not sure about its necessity.

I found the problem in suggested approach. I need to call:


Code:

vertices.dirty();
geometry.dirtyDisplayList();
geometry.dirtyBound();




Looks like even geometry.setDataVariance(osg::Object::DYNAMIC) is not necessary. I'm not sure how much performance i will get but I will keep you posted.
