[osg-users] Displaying Geode Bounding Box

Hi All, Is there a simple way to display the bounding box of Geode or Geometry? Or will I have to write up something to do it? Thanks, Sam ___ osg-users mailing list osg-users@lists.openscenegraph.org

Hi, Ok wow but what does it mean? Screen space sounds evil. I can't really get any hard results on Google for it. Basically the first hit gives an implementation guideline and links to the other techniques I've mentioned:

Re: [osg-users] Fwd: Slow down with shared nodes

Hi Robert, thanks for your help. I think the problem is the obj loader. I have done a quick review of the source code and the loader seems to create for each "f" line an own primitive set. This can be optimized. I will try to fix this in near future. I can not understand the difference between

Re: [osg-users] Fwd: Slow down with shared nodes

I've recently written some code to merge individual triangle strips by joining them using some degenerate (zero area) triangles. One issue that I've run into is that in wireframe mode this generated some very odd looking artifacts. Find the code here. It may need some adaptation for your use

Re: [osg-users] Fwd: Slow down with shared nodes

Hi Andre, Thanks for the file. I've just tried it on my Kubuntu 16.04. NVidia 760 with the OSG-3.4 branch and I see decent performance, the draw dispatch is bit more expensive than I'd usually expect for a model of this size but it's not widely expensive like you are seeing. The dataset itself

Re: [osg-users] QOpenGLWidget in osgQt

Valerian, Unfortunately we (osgEarth project) haven't found a solution to this yet.The underlying issue is that the QOpenGLWidget (unlike its predecessor the QGLWidget) is backed by an FBO, and this somehow does not interact well with an OSG camera using an FBO. The workaround is to continue

Re: [osg-users] QOpenGLWidget in osgQt

Thanks for both of your replies, that's really helpfull. Is it hard to deal with these conflicts with RTT camera ? Because I use it a lot.. Cheers, Valerian -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=70442#70442

The newer QOpenGLWidget works with OSG, but we have seen it have conflicts with RTT cameras. On Mar 8, 2017 5:21 AM, "Andre Normann" wrote: Hi Valerian, I have done this in the past. Attached you will find my GLWidget class which is using QOpenGLWidget. It is only

[osg-users] QOpenGLWidget in osgQt

Hi, I'm currently working on an app based on OSG 3.4.0 and Qt 5.6, targeting Win7 -- Win10. Everythings was fine and smooth with Qt 5.5. I'm using osgQt::GLWidget, which is based on QGLWidget. Since Qt 5.6, I've some hard unsolvable issues with QGLwidget. They are not related to OSG, and I

Re: [osg-users] Slow down with shared nodes

Hi Robert, hopefully I am getting closer. I find out, that the source model might be the problem. I exported an obj file from Bentley Microstation and imported into OpenSceneGraph. When I now export the scene into an osg file, I see a lot of PrimiteSets (e.g. > 1000). So I will end up with a lot
