[osg-users] A noob question: Can OSG do this?

2009-07-29 Thread Michael Angelkovich
Hello,

I've made an OpenGL application of considerable size and now I am exploring 
possibilities to display its results on a stereoscopic wall. Particularly, I 
will be let to try this on a VR system that is in possession of Technical 
University Sofia, in Bulgaria.

As the machine they use a cluster, where the master PC is connected to two 
rendering slaves. Slaves project the stereoscopic image to the wall with two 
beamers.

Right now I cannot say more about this cluster, but I hope you could still tell 
me if it should be possible to control this cluster through OSG. I would also 
appreciate tips on how to get started, since I have no previous experience with 
OSG. :) Today I had look at few pieces of code.

Thank you in advance for taking interest in this topic. :)

Hi, Michael,

OSG has certainly been used for cluster rendering, but it doesn't have 
any specific features explicitly designed for cluster rendering.  Take a 
look at the osgcluster example to get an idea of how you might approach it.


The other thing you mentioned is that you already have a sizable OpenGL 
application that you want to run on the cluster.  OSG is a scene graph 
API that sits on top of OpenGL and uses it to do its rendering.  This 
means you'll have to port your application to use OSG.  Porting from 
straight OpenGL to OSG is certainly possible, but it'll take some work.

Hi, Jason

And thank you very much for that answer. Now I got the picture of what OSG is. 
I will have look at the example you mentioned today or tomorrow. Should it 
prove to be a too large piece of work to do, I always have option to write the 
needed application extension from scratch. :)

Also see here, not specifically for stereo, but for distributed opengl.
