Re: [osg-users] how to get number of points and faces while osg reading in 3D models?

Hi long yan, You can refer to the class osgViewer::StatsHandler, it will show you how to get the number of vertices and primitives. Cheers, Su -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=42092#42092 ___

[osg-users] how to get number of points and faces while osg reading in 3D models?

when i use: node = osgDB::readNodeFile("cow.osg"); how can i get the number of points and faces in this model? who can tell me ? Thanks a lot! ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listin

Re: [osg-users] osg::Image Serialization

Hi Jeremy and Robert, In fact the osg::Image class can be derived and it is possible to write serializers for the subclasses. In osgWrappers/serializers/osg/ImageStream.cpp you will find an example which has no difference from other serializers. I'm not sure if this could work for osgCairo images,

Greetings all who attended! I had allot of fun and got allot of my 3.0 questions cleared up. Thanks for attending J-S and thanks for John for M.C.ing this BOF and the simulation BOF that I tried to attend before I got interrupted. Nice to see you all and putting a face on some of you on the Fo

[osg-users] [build] CMake fails to build for iOS from trunk

Hi, I am attempting to build OSG for iOS 4.3 using the latest source from trunk. My build environment is CMake 2.8.5 on Mac OS X 10.7 Lion, with all OSG dependencies installed via MacPorts. My CMake build environment works for other projects, ex. OGRE for iOS. To build OSG, I am using CMake l

Re: [osg-users] osg::Image Serialization

Hi Jeremy, I would have though it would be appropriate to support subclassing of osg::Image in the serializers. I'll defer to Rui to answer the specifics of how we might go about this. Robert. On Tue, Aug 16, 2011 at 5:42 PM, Jeremy Moles wrote: > Hello everyone; this is probably a question on

[osg-users] osg::Image Serialization

Hello everyone; this is probably a question only a few people could possibly, answer (Robert, Wang), but here goes: I have created a derived osg::Image class (osgCairo::Image), and this has worked just fine for the last few years. However, I want to add strong serialization support for my nodekits

Re: [osg-users] QT-OSG problem

I'm currently working on a better qt render thread integration that solves all these problems. It is already possible to open render windows from the render thread (using a qt blocking queued connection). Resize, minimize, close etc are communicated using signal-slot connections. The only requir

Re: [osg-users] QT-OSG problem

Hi Thomas, I think a bit more information would be useful. Werner is correct about Qt paint events in that all QWidgets must be created in the QApplication thread and cannot be moved to any other threads. If you're trying to use osg to render into a Qt-based window, this will be an issue. Ho

Re: [osg-users] QT-OSG problem

Hi Thomas, as far as I know Qt does not support painting in several threads. Preparation of scene data in a separate thread is no problem. But the painting process must be the GUI-Thread. - Werner - > Hi all! > > I am currently working on an application, that includes > > - an OSGViewer windo

Re: [osg-users] QT-OSG problem

Hi all! I am currently working on an application, that includes - an OSGViewer window, with a scene - a QT window, where I would like to adjust parameters of the scene in the other window (in real time). Both windows are handled in a different thread. The problem is, that if I make a window of

Hi, I guess I posted this in the wrong section previously. So sorry for the repost. My application loads a scenegraph where all children are OcclusionQueryNodes and no geometry. Based on the spatial location of the camera I load and attach the geometry to the respective OQNode and set the Queri
