Multiscreen with homography for dx11


#1

Hey there,

i am currently trying to combine the Multiscreen with the homography in dx11 to span a video over two projectors and beeing able to make some adjustments. i can deform the two parts of the the multiscreen with the homography node but the problem is that it does not keep its borders when i want to move only one corner of the image.
I think this has mainly to do with the matrix output of the multiscreen but when i take the matrix into the original positionInput then it is not working at all…

MultiscreenHomographyCombined.v4p (32.6 KB)

does anybody have an advice?
or is there a way simpler solution?

greetings knoeterich
