Re: [osg-users] Fwd: Ambient Occlusion Implementation 2 review
Hi Robert, I hope you understand the major idea behind this implementation. May you are able to boost it massivly or you are able to better integrate this algorithm. regards adrian Am 11.

Hi Adrian, I've not got most of the way through my submissions backlog - can finally see the light at the end of the tunnel :-) So I'm now in much better place to start looking at your Ambient Occlusion work. Do you have any updates to the source since the your code drop on the 21st of December? If you have any papers or webpages that explain the approach I'd welcome pointers to these as well.

Re: [osg-users] Fwd: Ambient Occlusion Implementation 2 review
Hi Adrian, Just a little note as I fly through my backlog on osg-users messages. I still don't have time to dive in with this new technique, please don't let me forget it though. I'm likely to be mostly handling my backlog of osg-submissions and doing office admin work this month as I've had to put off so much of this work in the last six months due back to back client work. I do still have some client work to do this month, but thankfully not overloaded so far so I'm hopefully of getting through my backlog, once I have place chase me if I haven't already dived in. In the meantime everyone else is welcome to dive in and provide you with feedback ;-) Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi all, The posted code is LGPL released. Well once the whole stuff gets integrated into OSG core, then all of the ssao stuff gets LGPL. May we have to rewrite the code for best fitting into osg core, but dont worry about licence. As i am the author of the SSAO idea and stuff, i can release it without any restriction. Only one wish i have: Lets mention me as the author of this spline based ssao :-) adrian 2011/12/21 Adrian Egli OpenSceneGraph (3D) <3dh...@gmail.com>: > Hi Glenn, > > Oh thank you to mention that, it was my fault.

Re: [osg-users] Fwd: Ambient Occlusion Implementation 2 review
Hello Glenn, The attached code is working, you can build it or just test on win32 with the build attached code. The only problem is, that the working code is only tested with NVidia GPUs and i am not sure that the way i implement the idea is OSG standard. What i am looking for is: - review with respect to correctness ( coding standard ) - review with respect to performance - and so on The whole project can be used as OSG (LGPL) licence , i am the author of the the whole stuff. My we should append the PDF close to the project, otherwise further users, authors dont really understand why and how the SSAO stuff is working. The whole project should deeply be intergrate into osg core with max performance and so on. I hope the request gets more clear now. if you have any questions please re-contact me /adrian 2011/12/21 Glenn Waldron : > Adrian, > > Can you clarify the situation here?

Hi all, The pdf can be publish on OSG web page if you like. I really like to contribute such nice implementations, but unfortunately i don't have enough spare time to work on. I hope the community can help me making the stuff robust and fast :-) The biggest idea is the math in the implementation, solving a linear equation. Any comments makes me happier :-) adrian 2011/12/21 Wang Rui : > Hi Adrian, > > I'd like to help if you think it possible.
