Re: [osg-users] Moving a line and its vertices

You need to dirty the display lists to tell OSG to send the new positions to the graphics card Code: geometry-dirtyDisplayList(); Or you can set the geometry to dynamic and it will dirty it on each pass. Can't remember the exact syntax, but search for dynamic. Martin --
