[osg-users] Rendering performance gain on 2 different Systems

2010-11-09 Thread Felix Engelmann
Dear OSG Community, I'm developing visualization software, which involves rendering of large point clouds. I optimized the scene graph in order to get better frame rates. In particular I now use osg::Geometry instead of osg::ShapeDrawable. I tested it on 2 different machines and got different

Thank you for the suggestions, I think a billboard with a gaussian texture is right what I need. Either a view-aligned billboard, which requires to update the width/height of the billboard - or a static billboard with 2 (or 3) crossing quads. A source code example would be great! Could you ask

[osg-users] Visualizing 3D-Points including standard deviation

2010-08-18 Thread Felix Engelmann
Hi, I need to visualize points in 3D, whose positions are Gauss distributed. The expected values and the standard deviations for each x, y and z coordinate are given. So, how can I do that with OSG? I could draw a sphere (using osg::SphereDrawable) with a fixed radius at the center and another
