Introduction
What can be done?
When working in a multichannel setup the Soft edge possibilities enable an image blending that gives the appearance of a single
image, thus achieving realistic immersion for the majority of simulation and virtual reality applications.

Soft edge : purpose
What is the Basic Principal of (electronic) Soft Edge ?
The principle of edge blending is achieved by linear modulation of the light output in the overlap zone so that the light output in that
zone equals the light output of the rest of the image.

Soft Edge Basic Principle
Internal versus external (Alpha planes)
The projectors offers 2 methods to achieve soft edging :
1.
Internal soft edges : the contour and shape can be adjusted in the projector using the soft edge edit wizard
2.
External Alpha planes : An external
fi
le is sent to the projector and is memorized. This
fi
le contains data corresponding to the
shape contour of the soft edge
