Example
Consider a four channel semi-circular dome display system with overlapping channels where it is not possible to fully capture all
blend regions in one single OmniBlend position.
The combined blend region of all four channels (label A in the image below) can be captured in an OmniBlend position, but since
the non-blend areas next to it should also be part of that position (see conditions above), it should be in or near the center of that
position. This results in a position as illustrated by dotted red line in image 8-117.

OmniBlend position: bad positioning
To capture the remaining area of the blend regions of this example (labels B, C, D and E in image 8-117), four more slightly over-
lapping OmniBlend positions are required (labels P2, P3, P4 and P5 in image 8-120).
