Hi Carsten,

This is a learning experience for me, too ;) I get quite interesting views on parts of OpenSG, I didn't even know were existing. > Try this: > > depthimage = OSG::Image::create(); > depthimage->set(GL_DEPTH_STENCIL_EXT, sizex, sizey, > 1, 1, 1, 0.0, NULL, GL_UNSIGNED_INT_24_8_EXT); > > The format has to be DEPTH_STENCIL and the data type is > UNSIGNED_INT_24_8 according to this in the glReadPixels call, according > to this page in the book "OpenGL Extensions Guide": > <http://books.google.com/books?id=VDqw6MK5NJMC&pg=PA345&lpg=PA345&dq=opengl+read+packed+depth+stencil&source=bl&ots=VbZVa8A85P&sig=gkf46Q9UYXp8dSrIlWsMnkIJ7ao&hl=en&ei=yiR1TN6XAoH58AbpxNypBg&sa=X&oi=book_result&ct=result&resnum=8&ved=0CEAQ6AEwBw#v=onepage&q=opengl%20read%20packed%20depth%20stencil&f=false> > Unfortunately this did not help. I read the specification on this site (http://www.opengl.org/sdk/docs/man/xhtml/glReadBuffer.xml). There the Parameter 'mode' has to specify a COLOR-buffer, but the depth/stencil-buffer isn't a colorbuffer or am I missing something? Maybe the problem is there?
