[osg-users] Shadowed scene distortion after 3rd window recreation
Hi. I'm implementing video settings change (and thus window recreation) in my game without game restart. I experience graphics glitches after re-running Viewer 3rd time: http://youtu.be/xOgTjENn2MM I recreate the window the following way: * Stop the viewer, stop threading. * Create new graphics context and attach it to the camera. * Run the viewer again. As seen in the video, ShadowedScene does not survive the 3rd Viewer restart and there appear some OpenGL errors in the logs. Can anybody help me, please? Thanks. PS: Full source code is attached to the mail, uses CMake and needs OpenSceneGraph-Data to run (dumptruck model), Page down recreates the window. osg_recreate_window.tar.bz2 Description: BZip2 compressed data ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Shadowed scene distortion after 3rd window recreation
I've found out that the glitches are fixed by simply recreating ShadowTechnique (SoftShadowMap). If anyone is interested, here's the working example: https://dl.dropboxusercontent.com/u/12634473/osg/osg_recreate_window_fixed.tar.bz2 2013/4/21 michael kapelko > For those who only read forum, here's the link to the full source code: > https://dl.dropboxusercontent.com/u/12634473/osg/osg_recreate_window.tar.bz2 > > 2013/4/20 michael kapelko > >> Hi. >> I'm implementing video settings change (and thus window recreation) in my >> game without game restart.
