Re: [osg-users] Idea to implement a kind of 'rubber mode'

That's a clever trick. Will it work with more than one layer of red-frame-green-symbol objects? Does it need to work in that situation? "Rubber" means something else in US English. ;) On Wed, Sep 12, 2018 at 4:18 PM Christoph Dohmen wrote: > Thank you, Laurens! > > Cheers, > Christoph > > ---

Re: [osg-users] osgText 3.6.3 crash

Hi Robert, That was the right hint and I must admit that I always forget it :-). Setting the datavaraiance to osg::Object::DYNAMIC fixed the crash! As for the other hints re performance, this is for sort of DEBUG mode for the sim so we are ok, but thanks for these as well! On Wed, Sep 12, 2018 at

Hi Glenn, I've compiled and run the example against the 3.6 branch with images from OpenSceneGraph-Data/Images and it runs on my Kubuntu 18.04/NVidia system without any obvious issue. Could you explain what the issue looks like so I could specifically test it? Laurens Voerman has kindly investig

Re: [osg-users] osgText 3.6.3 crash

Hi Nick, There are plenty of ways mutlti-thread setting of Text labels could cause problems if the threads reading from the Text are running in parallel to the ones setting it. A mutex "might" help but it could easily be done in the wrong way. If you are modifying text dynamically then you shoul
