[osg-users] Help: many cameras are rendering at the same time or one by one?
Hello, My question might be silly, but I really want to know about that. I wonder if there are many cameras (one main camera + many pre render cameras), will OSG (or grahic hardware) manage to make these cameras render one by one or at the same time? I have a programm concerning leveraging GPU parallelism capability, but I include many pre render cameras in it. So I would like to know how these cameras are managed. Thank you in advance!

So I would like to know how these cameras are managed. I believe this is determined by osgViewer's threading model: CullDrawThreadPerContext CullThreadPerCameraDrawThreadPerContext DrawThreadPerContext SingleThreaded etc. > Thank you in advance! > Shuiying -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.

Hi If you have one graphics device and one graphics context - all cameras rendered one by one (i mean actual draw calls) 30.01.2012, 23:27, "wang shuiying" : > Hello, > > My question might be silly, but I really want to know about that. > > I wonder if there are many cameras (one main camera + many pre render > cameras), will OSG (or grahic hardware) manage to make these cameras > render one by one or at the same time? > > I have a programm concerning leveraging GPU parallelism capability, but > I include many pre render cameras in it.
