Re: [osg-users] Lines being culled
Hi Andreas, I tried to recreate the problem with your model but haven't seen it yet. Could you record a camera path that demonstrates the issue and then post this so that we can test exactly the same thing as you. In osgviewer you can press 'z' to start recording the camera path then 'Z' to finish and replay the path. The file saved will be saved_animation.path, and to replace this in osgviewer you'd use: osgviewer result2.osg -p saved_animation.path Robert.

Re: [osg-users] Lines being culled
Hi Robert, Sure, here is the animation path. I zoom in and out a couple of times in the end of the path to show where it disappears. I wonder if it might be related to my ATI graphics card and its drivers...well, let's see if you can reproduce it first. /Andreas On 2012-09-04 16:38, Robert Osfield wrote: Hi Andreas, I tried to recreate the problem with your model but haven't seen it yet.

Hi Robert, Thank you, that did the trick. The latest ATI drivers didn't work with display lists either. So it seems NVidia is still superior with OpenGL compared to ATI, as always...
