Hi Robert & Delport, I have the setup with 4 cameras:
1st camera - the slave camera that inherit the master camera's relative frame and render the scene to 2 textures with color attachments. One of the texture remains as it is and other texture is left for further operation. 2. 2nd camera - the camera is hung under the 1st switch which does some operation over the one of texture specified above. The result of the operation is rendered to another texture using the camera. 3. 3rd camera - the camera is hung under the 2nd switch that does some further operation over the last result done in step 2. The result is rendered to the texture which was the input texture in step 2. 4. 4th Camera - is the HUD camera to visualize the output of the either of the above operation in step 2 / step 3. Since step 2 and 3 are Switches i make them only one enable at a time. The concepts are pretty simple as you can imagine. They have been picked from osgdistortion, osgprerender,osgstereomatch and osggameoflife. During the first pass , i make the first switch enabled with the keypress event and can visualize the scene. With the next key press event, i flip the texture for further pass over the result of the last operation, But the screen freezes without showing the result of the operation in the HUD camera. I need some hint on what might have gone wrong. If need more elaboration please ask. Thank you!
