Re: [osg-users] Best way to cull object hidden by a mountain

Hi Jason, I'm not making a full new application, I'm just upgrading the old OpenGL code to OSG, so there is lots of things I should have to destroy to use osgEarth, like the way tile are loaded, georeferencing management all that tools made to works on the rasters. My decision was to use

Re: [osg-users] how to detect if an object bounding box collision with the camera frustum?

Hi Sebastian. Thank you for your answer. What i want to do is to detect if a bounding box is inside the view frustum, but i don't know how to do. Can you give me some hints? I am new to osg. Cheers John SMesserschmidt wrote: > Hi John, > > > > Hi, > > > > how to detect if an object bounding

Re: [osg-users] Best way to cull object hidden by a mountain

I gotcha. In a legacy situation, it might be hard to integrate osgEarth properly. So, what is your current remaining obstacle? ​ ___ osg-users mailing list osg-users@lists.openscenegraph.org

Try CullCallback, in there you can get the handle of the CullVisitor and do something like this in your callback: CullVisitor* cv = nv->asCullVisitor() cv->isCulled(node) On Mon, Jun 27, 2016 at 8:30 AM, John Lee <357059...@qq.com> wrote: > Hi, > > I don't know how to judge if an object is in

Re: [osg-users] how to judge if an object is in the frustum?

Hi John, As Nick suggest you can use a cull callback to report back when a node and it's subgraph are likely to be within the view frustum, however, this is constrains you to doing the test in the cull traversal. However, if you want to do the test outside the cull traversal then you'll need to

Hey Valerian, Just curious, but what do you need to do with non georeferenced images that osgEarth can't do? Are you providing georeferencing yourself externally? Jason On Mon, Jun 27, 2016 at 6:05 AM Valerian Merkling wrote: > Chris, I already try to use osgEarth,

Hi, well, for this I think what Robert suggested suits better. I don't know the details of the Polytope that much but I think you just need to re-create the View frustum as a Polytope and do the intersectons... I hope Robert will shed more light into this On Mon, Jun 27, 2016 at 10:20 AM, John
