Re: [osg-users] [osgPPU] osgPPU with CompositeViewer

[Daniel Schmid]

Hello all

I bring this subject again to the surface. And I wonder if Art (or anybody else 
out there) has an opinion about this he would like to share...

In a composite viewer setting, views can be dynamically added and removed. In 
osgPPU, the Processor is part of the scene graph, but it has to be connected to 
a views camera...

So there are two problems which are not solved:
- How to disconnect a view (camera) from the processor and succesfully 
reconnect a new view to it?
- How to deal with multiple views visible at the same time? Multiple processors 
added to the scene graph?

I guess for the last point, there is a conceptional problem. The whole 
postprocessing should ONLY be bound to the view and leave no traces in the 
scene graph itself...

What do you think?

Hi,

Nobody tried this?

I made the simplest possible test i could think of and just set one UnitOut to 
the processor so there would be no actual action from the processor other then 
relaying the image forward. I set the processor with the view camera of the 
first view and it works fine. When i set it up with the second view camera it 
results only in a black screen. The viewport size and position seem correct but 
something goes wrong and i'm running out of ideas what it could be. Any good 
ideas?


Thank you!

Cheers,
Sami
