Introduction
What can be done?
When working in a multichannel setup the Soft edge feature enables 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 projector 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
Soft Edge Preparations
To ensure proper soft edge adjustment, be sure that the following adjustments are done perfectly on all projectors:
•
Geometry
•
Color Matching (Input Balance, Dynacolor ...)
When projecting on a cylindrical screen, the adjustments mentioned above can be done by using the projector
adjustments in combination with Polaris.
Polaris is a Test Pattern Generator software that can generate a user-de
fi
ned test pattern that is used to align
projection systems. It also has the ability to generate prede
fi
ned patterns for standardized projection sys-
tems. The software is developed to run on IRIX (Order numbers for Polaris: R9898300 for a 6 months license,
R9893301 for a full license).
