Selam Muhammed; This http://www.ub.uit.no/munin/bitstream/handle/10037/1065/thesis.pdf;jsessionid=C0E24ED29579BADBBA942B95B8C93B1D?sequence=1master thesis may help you to solve your problem about how OpenSceneGraph supports distributed rendering. Regards. Ümit Uzun 2011/4/10 Muhammed Kalkan kalkanik...@gmail.com Hi, Sorry if subject changed in previous topic. In my humble knowledge of distributed rendering, i think scene graph must have some kind of mechanism to sync frames to be rendered in each cluster (rendering machine). As your post states , a socket communication can transmit the sync messages. However what i wanted to know is how we build the structure for OSG to make sense of it. In short how and which part of OSG do we pass these sync messages to obtain distributed rendering. Thank you!

Re: [osg-users] Unable to place model on vpb terrain. How To ?
Sanat, Sorry for the inconvenience. The site looks to be working properly now. Glenn On Sat, Apr 9, 2011 at 8:30 PM, Sanat Talmaki sanat.sch...@gmail.comwrote: Hi Glenn, Yes that surely helped. I looked at the osg file generated by vpb and didn't see the ellipsoid model in there. Just didn't strike me that I would have to take a different route. P.S. I tried accessing the osgEarth website a couple of times last week but it seemed as though it was down. Thanks again.

Re: [osg-users] [3rdparty] Cloud node kit
Hi Sythel, regarding your cloud question: you can use a) Silverlining (supports OSG out of the box, for more sophisticated OSG integration take a look at osgVisual.) b) Simul TrueSky: looks fantastic, but afaik it soes not support geocentric maps out of the box. Provides a OSG integration, but is is a quite simple example. c) osgEarth's SkyNode and add the cloud rendering yourself. Google for OpenGL cloud to get papers and algorithm examples to add the cloud capability. Example: http://www-evasion.imag.fr/Membres/Eric.Bruneton/ osgVisual doesn't provide own sky algorithms it self currently. Depending how long you need your programm to run, oyu can play with Silverlining, it terminates without license after 5 minutes. The plans for osgVisual are: design a generic sky/athmosphe/cloud baseclass with with a simple sky/athmosphere implementation. Additionally it should provide implementations for Silverlining, simul TrueSky and osgEarth SkyNode integration. .. but just plans, time is limited.. for distributed rendering: look at the other thread.

[osg-users] [3rdparty] Distributed rendering (was: RE: Cloud node kit)
Hi, you can use several aproaches for distrubuted rendering: a) If you use the same software and same input data (- identical scene graph), you could transfere the camera settings and scene grpah modifications via settings. b) You could use equalizer to distribute the GL rendering: http://www.equalizergraphics.com/documents/WhitePapers/OpenSceneGraphClustering.pdf c) you could use the paper mentioned above. osgVisuals cluster is quite simple: it assumes the same databse and software on all nodes, so it has only to transfer the camera settings and distribute the node modifying actions to all clients. This way all cleints render the identical image. For each client you can specifiy a camera offset ( rotation/translation) to achieve the rendering of differned scene party. @Ümit Uzun : Thanks for the paper link, I'll read it carfully if it servers my needs :) Thank you!

[osg-users] [3rdparty] Distributed rendering (was: RE: Cloud node kit)
Hi, Thank you for all your responses. Umit, i have examined the paper and it can be a good starting point for a complicated distributed rendering and even can be a seperate plugin for OSG. But at the moment as far as i understand it is a bit far from being practical and didn't get tried out on real machines. However, thank you for your direction. Torben, than you for your inputs aswell. My goal is to achieve 3 rendering machines which all are rendering the very same image with different orientations. The aim is to have a 120 degree rendered image via 3 rendering machines. So only thing i really need is frame sync with the very same database and even very same camera position. For that purpose, do you think i should go with osgVisual or OSG alone is sufficient for that matter ? Thank you!

Re: [osg-users] [3rdparty] Cloud node kit
Hi, It seems i am going to have to write my own cloud system. I am shocked a bit for a great library like OSG doesnt have a plugin for clouds yet. However i dont have much time at the moment can choose commercial ones, but i have to try distributed rendering now thats not an option. I wrote my ideas to the other thread Thank you!

Re: [osg-users] [3rdparty] Cloud node kit
Sythel, you can also check out Delta3D. It is based on OSG and has several kinds of basic clouds. Of course they are not as good looking as the ones of the commercial sollutions, but they are free and can do quite a lot.
