Hi Wojtek,
I am not sure... I believe that it was impossible to use depth only FBO when they were initially introduced into OpenGL . But now it seems possible at least on NVidia's because I made such modificattion and it works ( in fact it gave me shadowing speedup improvements). But I did not try to submit this because I have not bothered to make it safe and I did not test whether mod does not break other RTT code. I may send this "as is" if you are interested.
I think if it gives a verifiable gain (less video memory used for depth component RTT) then you can submit it. As you know, submission does not mean that you need to be confident that it does not break anything, it means that you are sending it for review. Robert will check it out, if there are problems he might see them or if he's not sure then he'll call for more testing by others who use that functionality.
At least it would mean that some progress is being made in the right direction :-)
I hope you consider sending your changes, J-S -- ______________________________________________________ Jean-Sebastien Guay [email protected] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
