Edge Blending

Edge Blending occurs in both multi-projector display systems and in texturemaps. Both uses are similar, but with slightly different intent.

1. In multi-projector systems edge blending is the process of making sure that the point where the two projected images meet, or in some cases overlap, is seamless. The luminosity of both projectors is adjusted in the case of overlap so the combined image is no brighter than the rest, whilst the two images line up perfectly, so the user cannot tell visually where one projected image stops and the next begins. Instead the entire display looks to be one continuous display.

The task of adjusting an overlapping image so the combined outputs of the two projectors does not make the image too bright at tat point, is part of a process known as Linked Constant Light Output.

2. In texturemaps, edge blending is used to create seamless textures. The opposite edges of the texture graphic are adjusted so they match one another. This means that when two or more copies of the texture are laid side by side, the image flows contiguously, and there is no way to visually identify precisely where the edges of each texture are.

Texturemap edge blending takes place on all opposing edges so no matter how the texture tiles, it is always seamless.

Large Image Display: The Stepford Wives: Blending Displays with Drapes
There are several potential ways this display is working. One of the simplest and most plausible is a colour e-paper display behind a completely transparent display medium. The e-paper handles the picture, 'refreshing' the colour display to a matt black when the layer in front, the graphical display is activated. As soon as that deactivates, the 'oil' is re-drawn. Simple, elegant, and still far beyond us.
