Hi,
I dont think there are built in methods in osg for this. But I see it doable

I think you would want to put MatrixTransform on top of the pyramid node and
update its matrix either thru updatecallback or outside your frame.
Something like this

{

Is there any function to adjust the brightness or contrast of image in

If not, is it hard to add those functions in? Thanks!
