From Wang Rui, "Attachment is an example of rendering 3D scenes to high resolution screenshots. I uses a queue of Camera objects to do offscreen rendering with the Camera::attach() function. The entire picture is split into many tiles and it will take a few seconds while attaching and detaching cameras with tiles. You may select to output every tile as an image file, or combine them together to create a large poster, for example, a 12800 x 9600 image. Start the program like this: ./osgposter --output-poster --poster output.bmp --tilesize 800 600 --finalsize 8000 6000 cow.osg Adjust the scene camera to a suitable position and press 'p' or 'P' on the keyboard. Wait until sub-cameras dispatching is finished. And the poster file will be created while closing window. A 8000 x 6000 output.bmp will be created to show a fine-printed cow. :) The command below may also help: ./osgposter --help " 2010-12-13 21:37:37 +08:00			`SET(TARGET_SRC osgposter.cpp PosterPrinter.cpp )`
