Hi Robert, I want to come back to my original remark that culling does not work correctly with AutoTransforms and ROTATE_TO_SCREEN. I have modified the example osgautotransform.cpp by adding a new class that contains an AutoTransform and a drawable. An object of this class is added to the

[osg-users] AutoTransform, ROTATE_TO_SCREEN and small feature culling

Hi, I found a very old article covering this issue: https://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg15948.html. In the meantime it seems to be that proposal (2) has been implemented and the AutoTransform's computeBound() method returns an invalid bounding sphere during the

Re: [osg-users] Show part of geometry which intersects a specific area

Hi, you may use a PolytopeIntersector to get all items intersecting the rectangle. Afterwards, you may modify the node mask of the found items: set a specific bit of the node mask to one if it is found by the PolytopeIntersector and to zero if not (by implementing a visitor inspecting the

Re: [osg-users] DatabasePager::DatabaseThread is crashing when DatabasePager has been deleted

Hi Robert, I think that it has nothing to do with Clang or GCC. I did some further investigations and probably found the bug. In DatabasePager::requestNodeFile you find the following code: Code: if (!_startThreadCalled) { OpenThreads::ScopedLock lock(_run_mutex); if

[osg-users] Database pager and failed loading of PagedLOD's children

Hi, I use PagedLODs and the database pager to load dynamically nodes. Here is the pseudo code: Code: pagedLOD->addChild(nodePtr,limit,std::numeric_limits::max); pagedLOD->setFileName(1,fileName); pagedLOD->setRange(1,0.0,limit); In case the pseudo-loader for fileName fails I would

Re: [osg-users] Database pager and failed loading of PagedLOD's children

Hi Robert, the problem seems to be that the database pager (respectively the paged LOD) keeps trying to load the node that fails to load. To stop this I somehow have to tell the paged LOD to stop loading the children, or I have to modify the limits. But for doing so I need to know when a child
