Hi, i have a question about using VBOs and Display Lists in osg
according to my OpenGL book, both methods will optimize rendering due geometry is moved to the graphics-hardware. it also says, a constraint when using display lists is, that data can't be changed afterwards. so its great for rendering the same object multiple times, but not when you want to modify it. in my application i'm rendering a forest. i want to have a handful of different tree sprites, which will vary in size and color (but not in texture). as far as i know osg uses display lists by default - will i benefit from a switch to vertex buffer objects, because in this case many states will stay the same and only geometry will vary/be modifed through the different tree sprites? best regards, christian ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=9755#9755 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
