Hi,
sorry, I can't quite follow the code, but do something like this:
input_texture -> ProcessPass[0] -> Out[0]
Out[0] -> Process[1] -> Out[1]
Out[1] -> Process[2] -> Out[2]
Just make a chain...
Depending on how many passes you have enables, view one of the Out[]
textures.

Hi Delport,
I have added one more pass branch to the graph and i can see a new behavior.
The code snippet for it as follows:
***************************************************************************'
//the first pass in the scene, with the key press the following do the blur on
the initial scene
_ProcessPass[0] = new
ProcessPass(_OutTextureBlur[0].get(),_OutTextureBlur[1].get(),
_TextureWidth,_TextureHeight);
//takes the input of the first pass and blur it even more, and the screen
freezes
_ProcessPass[1] = new
ProcessPass(_OutTextureBlur[1].get(),_OutTextureBlur[0].get(),
_TextureWidth,_TextureHeight);
//SOMETHING INTERESTING HAPPENS HERE!
//The following pass make the last scene less blur instead of more blur than
the last frozen scene, but the scene is not frozen anymore, i can rotate around
the model, zoom in and zoom out
_ProcessPass[2] = new
ProcessPass(_OutTextureBlur[0].get(),_OutTextureBlur[1].get(),
_TextureWidth,_TextureHeight);
_BranchSwitch[0]->addChild(_ProcessPass[0]->getRoot().get());
_BranchSwitch[1]->addChild(_ProcessPass[1]->getRoot().get());
_BranchSwitch[2]->addChild(_ProcessPass[2]->getRoot().get());
'***************************************************************************
From the above description it seems that the last pass is reversing the blur
effect.
In ProcessPass[1] - the scene is getting more blurry. It seems that the
ProcessPass pass is doing the job right, but in the ProcessPass[2] it isnot.
Any idea?
Thank you!
Regards
Sajjadul
