Global Functions
Correct for the flat to round surface distortions
12. On any of the Global or Graphic Effect Mode channels set to Spherical Control 2 (DMX = 254), and then use the associated
Modifier 3 to compress the grid edges adjusting the bend in horizontal grid lines. This adjustment should not be used to fill
the projector output horizontally. Instead, it should be used in conjunction with the Spherical Mapping Global Effect Modifier
1 to control the longitude angle of the projected image. Global Effect Modifier 1 should be maintained close to the theoretical
longitude angle.
13. Use Modifier 1 and Modifier 2 to adjust the amount of bend, up or down, in the horizontal lines of the grid. Modifier 1
controls amount of correction. Modifier 2 controls where the center of correction occurs.
14. If the spherical mapping effect is being used in conjunction with the Collage Generator effect, select the Enhanced Collage
Generator option (DMX = 141) in the other Global Effect channel now. Set the appropriate grid size and grid elements
selected with the internal Collage alignment grid enabled. Go back through steps 1 through 11. Remember that pan and tilt
adjustments are also available when using a DML-1200 w/Axon fixture.
Now you have a rough adjustment of the spherical mapping effect. From this point, finely adjust all the parameters until you bring
the output to the desired shape.
When fine tuning Spherical Mapping adjustments, remember the following:
• The Graphic Object effect 253 Modifiers 1 and 2 have a major influence on the shape of the vertical lines.
• The Spherical Mapping Global Effect modifiers can be used to provide fine control of the shape of the vertical lines, but should
be within several degrees of the expected latitude and longitude values.
• The Graphic Object effect 253 Modifiers 1 and 2 are used to finely adjust the vertical bend in horizontal lines.
Spherical Mapping Considerations
• If the fixtures are arranged symmetrically around the sphere, the adjustment made to the various control Modifiers of Global
and Graphic Spherical Mapping effects will be the same or nearly the same when the fine tuning is complete. You can save time
by selecting the Modifier on all the fixtures you are using for the Collage and making each adjustment on all the fixtures
together.
• Projector Pan, Tilt, and Zoom also affect alignment.
• Don't make small changes until the alignment is roughed in.
• When alignment doesn't seem to be working, record and store your current settings, then go back to the default values and
begin again.
• The longitude angle is the angle between fixtures from the vertical axis of the sphere and should be defined in your lighting
plot. The plot should also give you a good idea of the latitude angle. The final values and those theoretical values should be
close.

4.12.6 Creating Custom Content for the Collage Generator Effect

There are two main steps to process HD footage into digital content compliant media for use with the Collage Generator.
First, acquire or commission High-resolution media footage or stills. In most cases, scaling and cropping of the media is a simple
process. However, certain types of media such as footage of people or round objects like planets may require more sophisticated
cropping and scaling to optimize display in certain aspect ratios.
Then, save your media at Photo jpeg 95% or a non compressed format (these can be very large files) to use as a master file. Or, if
you are an intermediate video editor yourself, there are many Video editing packages that will allow you to size and optimize the
master for your application.
Once the master file is created, you will need high-definition encoder software.

4.12.7 Collages Using SDI Input

DML-1200 w/Axon fixturess can create Collage arrays using live SDI input. All the media servers used to project a Collage need to
be receiving the same source input signal to use video as a Collage feed.
