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 surrounds the limits of the distorted image.
