Hi,
I have some big scenes (just one ive file each one). After the viewer is
initialized i load one of these scenes (imagine a long road with curves) and i
make the camera go along a path.
The problem is that i notice some frame drops (peaks, mainly in curves, when
new geometry comes in view). When i make a second pass, this frame drops
disappear. I also used a small app for testing graphics memory and i saw that
in these peaks, graphics memory usagge grows, so i guess that the main problem
are textures being loaded in graphics card.
Looking in the forum I found some interesting threads about using
GLObjectVisitor, but this didnt solve the problem. I dont know if i did
something wrong or just this was not the solution:
struct CompileCallback : public osg::Camera::DrawCallback
{
virtual void operator() (const osg::Camera& camera)
{
osgUtil::GLObjectsVisitor gov;
const_cast<osg::Camera&>(camera).accept(gov);
}
};
view->getCamera()->setPreDrawCallback(new CompileCallback);
I also tried a solution given in this post:
http://forum.openscenegraph.org/viewtopic.php?t=3330
viewer->setIncrementalCompileOperation(new
osgUtil::IncrementalCompileOperation());
After viewer initialization (and before loadint the scene). The results where
just the same.
Is there any way to preload textures in graphics card? Any other sugestion?
Thank you!
Cheers,
Joseba
