[osg-users] what's wrong with removechild
Hi, I want to pick one node using mouse. then the node deleted. but I failed. I don't know why. the nodepick.h attached. the osg::Node* pNode can be picked. and it can be changed to red. but the following mViewer-getSceneData()-asGroup()-removeChild(pNode); failed. I also used m_Rt-removeChild(pNode); failed again. So puzzled. help me plz. Thank you!

Re: [osg-users] I created 10000 cylinder, osg run very slow
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_ptrosgShadow::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. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=64464#64464 Attachments: http://forum.openscenegraph.org//files/cabletray_292.jpg ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] How to delete Node from the root
Hi, I use addchild to create root tree. Yeah, we can use removechild to pruning. But the removed node is still in the memory. I wonder how i can delete it totally from the memory. We can get any node using computeIntersections(x,y,intersections). We got the osg::Node *node, then free(node), the node is null. but we new many kinds of objects when new node, e.g., osg::Image image, osg::Texture2D texture, osg::ShapeDrawable doorShape and so on. how can i delete these pointers. Need I create free function for each node? Thank you!

[osg-users] I created 10000 cylinder, osg run very slow
Hi, I need to use cylinder to simulate the “ladder”. So there are many cylinder to create. I new a osg::Geode , and then use it to new 1 osg::MatrixTransform, all these osg::MatrixTransform were added to one group. But the program runs very very slow. In fact I create the same scene using opengl, the program runs quickly. How can I upgrade my program? thanks. Thank you!
