WhySoft Edge ?
What is the Basic Principal of Soft Edge ?
The principle of edge blending is archived 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 Preparations
To ensure proper soft edge adjustment, be sure that the following adjustments are done perfectly on all projectors:
•
Convergence (Electronic Convergence).
• Geometry
• Color Matching (Color Temperature, Input Balance, Gamma)
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-defined test pattern that is used to align
projection systems. It also has the ability to generate predefined 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).
