Re: [osg-users] Saving the result of an IntersectVisitor

How about just a vector of vector of integers? Each integer would represent the nth child of the previous node, and each vector of integers would represent a whole nodepath. So "4 6 7" would mean the 7th child of the 6th child of the 4th child of the root node. -- Terry Welsh mogumbo 'at' gmail.c

Hello Dario, Yes, I've made a Visitor to setUnRefImageDataAfterApply(false) for all textures properties and now works like charm. If you want to have less code to maintain, you could just use the osgUtil::Optimizer::TextureVisitor like this: osgUtil::Optimizer::TextureVisitor visitor(true,

Martin, here's one method. It's a little pricey since you need to attach it as both a cull and update callback. I've left out some of the code but you get the idea. Basically you use the MVPW matrix to drop into screen space, apply the offset, then go back to object space. struct TextOffsetCB : p

Re: [osg-users] Saving the result of an IntersectVisitor

Another idea I had was to use a NodeVisitor to predictably - probably sequentially - name each node in a model after I load it. They I could record a NodePath as a vector of names. This idea is my current favorite, but I'm still hoping for an easier solution. -Todd On 08/25/2010 08:44 AM, T

There is difference in Opengl drivers provided by Nvidia and ATI. If you set nvidia card as primary display then it should work across all screens (including the ones used by ATI cards). In case you are setting ATI as your primary display device then the application may crash as there are some Ope
