Hi list, I have 4 cameras independent of each other, and each one covers a 4th of the screen. I want to take a screenshot of each one then put the 4 images into a single texture. Also note that I'm not using the composite viewer.
My first problem is that the normal approach is to attach a texture to a camera, but this means that I will get the data from the next frame since I will have to render it again; I suppose I could render the image again but this seems like a waste, instead I would like to copy the entire screen, what would be in OpenGL the front buffer of the entire window. The second problem is that, in case that I'm forced to waste resources by redrawing the frame camera by camera, how could I join the 4 textures? _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
