Hi, What GPU/OS/driver are you running?
Could it be related to the non-conformant behavior of the driver wrt geometry shader initialization, as discussed in January and again in March; see: http://www.mail-archive.com/[email protected]/msg06033.html http://www.mail-archive.com/[email protected]/msg08464.html If so, it's a 1-character fix, but it seems so far no one has had a chance to make the fix, test for regressions, and send a patch to osg-submissions. If the proposed fix solves the issue, please do officially submit a fix. thanks -- mew On Tue, Apr 29, 2008 at 7:01 AM, Roni Rosenzweig <[EMAIL PROTECTED]> wrote: > I also get a similar warning (OpenGL error after RenderBin::drawInner()) > when running the osgshaders example. > It only happens on the first frame. > I noticed that if I remove the shaders, the warning does not come up. > Any problem that could happen with shaders on the first frame of the > application? > (in osg 2.2 there were no warnings) > > Roni > > ~~~~~~~~~~~~~~` > > > > > > Hello > > I switched to osg 2.4 today (from 2.2) and started receiving a warning: > > > > Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,) > RenderStage::drawInner(,) FBO status= 0x8cd5 > > > > It's only printed once. > > My application seems to work fine so far (haven't tested everything yet) > but any ideas why this warning comes up? > > > > I'm using a camera rendering to FBO, and a post-render hud camera showing > the FBO contents as a texture on a quad. > > > > Roni > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > > -- Mike Weiblen -- Austin Texas USA -- http://mew.cx/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
