Hi Robert, The problem may be in the way I am linking with OSG libs in my Makefile. To check that I tried to create a Makefile for the osgintersection example. when I run cmake I get the following: The C compiler identification is GNU -- The CXX compiler identification is GNU -- Check for

[osg-users] Swapping ref_ptr

::Group; foo(myGroup); // now I need myGroup to point to MatrixTransform without noticing it } Is this going to work? I have no compiler on this maschine to test right now so I am just assuming and browsing the docs. Thank you! Cheers, Sam -- Read this topic online here

Re: [osg-users] Swapping ref_ptr

Hi, passing a ref_ptr by reference. This sounds somehow strange to me. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=29517#29517 ___ osg-users mailing list osg-users@lists.openscenegraph.org

[osg-users] gDebugger see memory leaks in 14 lines of set up code when FBOs are used

Hi, I spent the whole day chasing a weird memory leak on my GPU. The following code is part of a (not working well) FBO render solution. Code: #include osg/CameraNode #include osgViewer/ViewerEventHandlers void foo() { osg::ref_ptrosg::Camera c = new osg::Camera();

[osg-users] Simple Loading Tutorial

Hi all, I've recently been trying to get my head around OSG, been trying the inbuilt examples and am not getting very far. I thought i'd check out the OSG tutorials but the site seems to have been down for the last few days now. Is there any specific example that I should be looking at just

Re: [osg-users] zbuffer issue

Hi, thanks for all the reply like colin noted, the render problem vanished as i stripped off the offsets which caused the large coordinates and work now with localized coordinates. if i ever need to display the real coordinates in an text-insert, i can re-add the stripped offset before display

Re: [osg-users] zbuffer issue

i forgot three things to mention: 1.) as i mentioned above, i place adjacent trees into one geometry. e.g. a geometries' vertex-array has numberOfAdjacentTrees*8 (=double quads ) entries. but i use only one primitiveSet to construct the geometry. i hope this is okay.

Re: [osg-users] zbuffer issue

Sorry, for another posting: i just tested the original one drawable per tree implementation with such large coordinates again and noticed that it also tends to flicker, as well hidden faces were revealed also. i couldn't encounter the outer mentioned problems. thanks in advance, christian

Re: [osg-users] get the x-axis angle of a rotation

Hi james, regarding your last post, did you mean that you also tried to extract angles from a rotation with the website's matrixToEuler or a similar approach, but you encountered problems that were depended on your current camera-orientation? i think the same happened to me: i wanted to get
