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).
Note that the soft edges are placed on the distorted image i.e. it surround the limits of the distorted image.

Soft edge adjustments
What can be done ?
The soft edge adjustment consists of the adjustment of one or more edges of the image. Each zone where the blending is to be
applied is divided in 16 zones delimited by 25 adjustments points. These points are numbered from 0 to 25 and can be shifted to
the desired location to determine the total size and shape of the soft edge zone.
This high number of adjustment points allow to meet any complicated soft required for special curved screens.
The default soft edge size (prior to the adjustment) corresponds to 12.5% of the image.
