Re: [osg-users] "Error: Not able to create requested visual." for osg application utilizing multi-sampling, ran with optirun.

This might be simply a driver limitation. Not all hardware and drivers support multisampling. For example, I'm using OSG on Mesa + Intel HD Graphics which doesn't support multisampling at all. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=64858#6

Hi, I am wanting to do a dust cloud when an entity (helicopter) lands on a terrain. Ideally, would like the color of the dust cloud to be similar to the material/texture that the entity is on. Is there a way to do a "material/texture color" query based on an entity position, kind of like an LOS

Hi, In the meanwhile, I was working further on the topic - and cracked it this time, I think. First and foremost, I use OpenSceneGraph 3.3.8 (still) and compile it for Android, while having the necessary 3rdParty-folder inside the OpenSceneGraph root folder (little suggestion: at some point thi

HI Erik, The constructor takes a reference not a pointer so try: osg::ref_ptr < osg::Vec3Array > pCopy = new osg::Vec3Array(*pVertexArray, osg::CopyOp::DEEP_COPY_ALL); Noe the *. Or use osg::clone() i.e. pCopy = osg::clone(pVertexArray->get()); Robert. On 20 August 2015 at 18:30, Erik He

[osg-users] Vec3Array Deep Copy

Hi everyone! I have a simple question but I just can't figure it out. What is the proper way to copy a Vec3Array? The code below is not right: Code: osg::ref_ptr < osg::Vec3Array > pVertexArray = new osg::Vec3Array; ... osg::ref_ptr < osg::Vec3Array > pCopy = new osg::Vec3Array(pVertexArray,
