Re: [osg-users] Robert: I figured it out :-) (was: Is it possible to know when the node-graph is 'dirty'?)

Hi Robert, My current code instances a new one each cull traverse. I wonder if that means I get a sizeof(osgUtil::RenderBin) memory leak each cull-traverse? Anyway, I am going to try to multi-buffer it. I should be able to count the number of cull-traverse calls I get for each update

Hi, I dont see that you are doing anything wrong... It was not working for me either though but I think you messed somehow the logic up. Here is an example based on what you sent which makes the model (I used cow.osg) fade in/out. Hope this helps - Original Message From: Dieter

Hi Robert, Hi Viggo, The rendering backend uses ref_ptr's so there shouldn't be any leak, assigning the new RenderBin will lead to the previous one being deleted. Yep I figured out that one :-) Rather than second guess what will be need might I suggest you maintain a recycling list of

[osg-users] How to read out the coordinate info from model files

Hi all, I'm trying to import some 3ds models (using osgDB::readNodeFile) into an osg programme. Now the problem is that: Is there any way that we can read the coordinate information out from the models since 3ds models have saved the position (the model center) coordinate information themselves?

Re: [osg-users] osg pick problem

Hi Forest, The osg::Drawable class has an accept(PrimitiveFunctor) method that is used to extract the geometry information in a way that the IntersectionVisitor can use, so if you want picking support then you'll need to implement this. Robert. 2008/7/25 forest37 [EMAIL PROTECTED]: hi,all

Hi Bruno, osgViewer != osgProducer, but pretty well all of Producer functionality is available + much new functionality and flexibility. Naming has changed to better reflect OpenGL naming conventions - something that the core OSG has always done, Producer diverged from this occassionally. FYI:
