[osg-users] I created 10000 cylinder, osg run very slow

[LUO Jianguo]

Yeah, it's not ladder. It's cable tray in the power plant. . In fact, I used not more than 1000 cylinders, osg runs very slow. I ignore the cylinders, it gets much faster.

then I have to disable shadow,
osg::ref_ptr<osgShadow::SoftShadowMap > ssm = new osgShadow::SoftShadowMap;
// 	float bias = ssm->getBias();
// 	ssm->setBias(bias*2.0);
// 	mShadowedSceneRoot->setShadowTechnique(ssm.get());
// 	mShadowedSceneRoot->setReceivesShadowTraversalMask(ReceivesShadowTraversalMask);
// 	mShadowedSceneRoot->setCastsShadowTraversalMask(CastsShadowTraversalMask);

the program runs fast again.

So I enable shadow again, and disable the cylinders // setNodeMask(CastsShadowTraversalMask);
the program still slow.

Maybe I can't draw my power plant prefectly, without shadow.

And would you please answer my another question in the other article, it's still about the power plant. thanks.
