Re: [osg-users] Check support for multi sampling

Hi Per, If the visual isn't supported then osg::createGraphicsContext(Traits*) will return NULL, so if get a null back then you can relax the Traits and try to create the context again. Robert. On Sat, May 17, 2008 at 12:50 AM, Per Rosengren [EMAIL PROTECTED] wrote: I set multi sampling with

Re: [osg-users] problem with multitexturing in latest svn?

HI Luigi, I've just tried under Kununtu with OSG SVN and marmol4.ive loads just fine and I get the snap_ok.jpg result. I haven't checked in anything that I'd expect to cause problems with multi-texturing, kinda odd to see you have problems with. Best I can recommend is try a clean build.

Re: [osg-users] VPB-0.9.7 paged-LOD hangs

Hi Renzil, The VirtualPlanetBuilder is not written to be used for both viewer and building at the same time, if it hangs or crashes then so be it, it's not something it's been designed for, if it worked with VPB-0.9.1 most likely it was a fluke, and not something you could have relied upon as

Re: [osg-users] traverse

HI Valary, The update and event traversals both have use a mechanism that stops traversal when no children of a node contain any nodes that requiring traversing. This feature is key to maintain good performance on very large databases, without it the update/event traversals would take dozens of

Re: [osg-users] traverse

Hi Valery, Geode's are meant to be leaf nodes, so are no intended to have children other than drawables - which is why traverse() isn't appropriate in this case. If you do want to customize behaviour then could implement override the Geode::accept() method, this is called before the

Re: [osg-users] Strategy for implementing dynamic vertical exaggeration of VPB models.

Hi John, VPB builds purely static databases that are stored on disk to be later loaded by the runtime that visualizes it. Since you want to vary the vertical exaggeration at runtime then the solution will have to be entirely on the OSG side, VPB actually has little to do with the actual

Re: [osg-users] How to make the camera rotation not spin when it is dragged quickly with the mouse

Hi Matthew, If you release the mouse button while moving the mouse then the Trackball and TerrainManipulators will interpret this as a throw. So users find this really natural, others find it awkward to get used to. Right now there isn't any options built into the these manipulators for

Re: [osg-users] NodeTrackedManipulator constantly segfaulting

Hi Alejandro, I haven't heard of NodeTrackManipulator sef faulting before, so this is a new one, I'd guess it would most likely be a usage issue, but perhaps you have uncovered a bug in the manipulator. First thing to test would be to run the osgsimulation example to see if that runs stable.
