5.2.39 Spherical Mapping
Spherical Mapping adjusts a rectangular output to project on a portion of a sphere. It is especially useful for projecting a Collage
onto a sphere or a portion of a sphere. Spherical mapping utilizes a total of nine Effect Modifier parameters to adjust positioning.
In addition to the three modifiers associated with the Global Effect, two Graphics Object Effects provide six additional Modifier
parameters. Use these adjustments in conjunction with Keystone parameters and Ratio parameters to refine the output shape on
the spherical surface.
For a more information on Spherical Mapping, (see
5.2.39.1 Spherical Mapping, Outside
Effect Mode parameter DMX value = 142
This effect corrects shape distortions and controls blending for Collages projected onto the outside surface of a sphere.
5.2.39.2 Spherical Mapping, Inside
Effect Mode parameter DMX value = 143
This Global Effect corrects shape distortions and controls blending for Collages projected onto the inside surface of a sphere.
5.2.39.3 Modifier Parameter Adjustments for Spherical Mapping
When Spherical Mapping is selected, the associated Global Effect Modifier parameters adjust as follows:
Modifier 1: Adjusts the longitude (horizontal) angle. A value of 0 = no adjustment. The number of degrees of angle increases as
you increase value to maximum at 255 (100%).
Modifier 2: Adjusts the latitude (vertical) angle. A value of 0 = no adjustment. The number of degrees of angle increases as you
increase value to maximum at 255 (100%).
Modifier 3: Adjusts the center of the latitude angle. A value of 128 = no adjustment and assumes the center of the latitude angle is
at the "equator". Values below the midpoint move the center of the latitude angle down with 0 = maximum distance below the
"equator". Values above the midpoint move the center of the latitude angle up to 255 = maximum distance above the "equator".
When the Spherical Mapping effect is selected in a Global Effect parameter and a Graphic Effect parameter's DMX value = 253, the
Graphic Effect Modifier parameters make the following Spherical Mapping adjustments:
Modifier 1: Controls the vertical offset of the projector. A value of 128 = no adjustment. to maximum at 255 (100%). Values below the
midpoint compress the grid toward the "equator". Values above the midpoint stretch the horizontal grid lines away from the
"equator".
Modifier 2: Adjusts the vertical offset of the sphere. A DMX value of 128 (50%) = no adjustment. Adjusting toward 0 moves the
center of the adjustment down toward the bottom of the image.
the top of the image at a DMX value of 255 (100%).
Modifier 3: Adjusts to the size of the sphere. A DMX value of 64 (25%) = no adjustment. Adjusting toward 0 compresses the grid
toward the vertical center.
(100%).
When the Spherical Mapping effect is selected in a Global Effect parameter
the Graphic Effect Modifier parameters make the following Spherical Mapping adjustments:
Modifier 1: Corrects the vertical bend. A value of 0 = no adjustment. Values below the midpoint bend the horizontal lines toward
the "equator" to a maximum at 255.
Modifier 2: Adjusts the center of the vertical bend. A DMX value of 128 (50%) = no adjustment. Adjusting toward 0 moves the
bend center down to the bottom of the image. Values above the midrange move the bend center up to the top of the image
at a DMX value of 255 (100%).
Modifier 3: Adjusts the center of the horizontal bend. A DMX value of 64 (25%) = no adjustment. Adjusting toward 0 bends the
vertical grid lines toward the center of the output. Values above the midrange bends the lines away from the vertical center to a
maximum at 255 (100%).
Modifier channels for Effect Mode 1 are labeled as CMY in the Wholehog system so you can also make use of the
color picker, HSI, and other Wholehog functions. Use the CMY parameter controls to adjust the three Effect Mode 1
Modifier parameters for both the Global and Graphic fixture types.
The default for Effect Mode 1 is set to CMY1 as well. Modifier channels for Effect Modes 2 and 3 are labeled Mod 1,
Mod 2, and Mod 3.
