hello,everybody .My situation is that I use three projectors to playback vides ,projecting on a circular wall (which is not flat ）.I have used the multiscreen to realize this ,but I have some annoying problems as follows.
1) Is there a method that I could change the gamma value
dynamically .If I set a certain gamma value to playback videos,sometimes
the areas of softedge is too bright and sometimes too dark。
2） because the wall is arc. the projectors has a distortion in the
overlap areas,is there any way to correct the distortion .I have corrected
the distortion with grideditor node ,but the overlap area of the two
projectors was corrected at the same time . I mean that I want to correct
the overlap area of the two projectors independently.
any suggestions is appreciated ,thanks very much
