By the positioning of two milky films the colour within the tubes is mixed. Therefore an image pixellated in the tube grid appears on the backside of the projection. The software program vvvv prepares the image digitally for the projector, corrects the geometry according to the projection angle and softens the edges. Thus a perfectly seamless projection image made up from four projectors is created. Behind the scenes three powerful PCs work on image allocation, geometry correction and transfer of the video signals. The VJ only has to operate the computer with the VJ software and can arrange the image at his will with a few easy steps.
