Geometr y Engine (continued)
• If Geometr y Engine is set to Rotation, set the Rotation slider to rotate the image on the screen.
1 DMD position
The DMD is not rotated.
2 Area outside DMD
The corners of the rotated image leave the 
DMD and appear cropped.
3 Angle of rotation
The angle equals the Rotation setting.
In this example the angle is 25°, therefore 
Rotation = 25.

Warp Map
Using DP Warp Generator, an external Digital Projection computer application, up to eight 
customized warp maps can be created and uploaded to the projector. If Geometr y Engine is set to 
Warp, and any warp maps have been uploaded, you can select from the drop-dow\
n list.
1 Distorted image
The image is projected on an uneven surface.
2 Warp map
The map mirrors the surface - raised areas on the surface correspond to \
hollow areas on the map, and vice versa.
3 Corrected image
With the warp map applied, the projector compensates for the surface and\
 the projected image appears undistorted.

Edge Blend menu
Over view
When several projectors are used to create a large tiled 
image, the edges need to be blended to avoid the overlaps 
appearing brighter than the rest of the image.
As it is not possible for any projector to produce an 
absolute black, any ‘black’ areas in the overlapped edges 
may appear slightly less dark than those in the rest of the 
image. Black Level Uplift can be used to counteract this 
effect, by raising the black level of the rest of the image. 
The amount of uplift required will be either x2 or x4, 
depending on how many images are overlapped, as shown 
in the examples on this page.
Image brightness changes from one point to another, 
within the same blended region. If the same level of black 
level uplift is applied throughout the blended region, the 
overlapping edges may still be visible on the screen. 
Therefore, brightness in these areas is decreased 
gradually, using an s-curve factor. S-Cur ve Value is used 
to control the steepness of the decrease.

Array Width and Height
• Set this to the total number of projectors in the array. None of the other 
options are available until one of these two settings is greater than 1. The 
maximum number of projectors is 4 x 4.
Array H Position and V Position
• These two parameters need to be set correctly for each projector in the \
array, so that it can determine which edges are to be blended. Sometimes 
only one edge overlaps, sometimes two, three or four.
Example
The illustration shows an array of sixteen projectors. Array Width and Array 
Height of all projectors have been set up as follows:
• Array Width = 4
• Array Height = 4
Array H Position and Array V Position of each projector have been set up to 
reflect its vertical and horizontal position in the array.
The settings for the third projector in the second row 1 are:
• Array H Position = 2
• Array V Position = 1

  None of the other items in this menu

Width
 or the Array Height setting

  The position numbering starts from 
zero, so the top left projector is at 
position  H 0, V 0.
 Which settings are available in these 
menus depends on:
 
●   the number of projectors in the 
array
 
●   the position of the projector in 
the array
 An image like the one shown here 
can be produced by an array of 16 
projectors only if 
Segmentation 
is set to 
ON, or if an external tool 
is used to split the image into 
segments. See Segmentation 
further in this section.

S-Cur ve Value
• In the regions where two or more projectors overlap, the brightness of 
the signal is decreased to blend the images. S-Cur ve Value controls the 
steepness of this decrease.

S-Cur ve Value (continued)
When images overlap, the area of overlap receives light from all overlap\
ping sources. Without S-Curve, the overlapping edges would be 
brighter than the rest of the image, as shown in Fig. 1.
If two reciprocal s-curves are used to control the amount of light from \
each source in the overlapping region, the total amount of light in the \
region would remain constant, as shown in Fig. 2.

Blending
This setting enables s-curve blending, or displays an align pattern to help define 
overlaps between segments.
Set Blending to:
• Off
Edge Blend is not used.
• On
S-curves are enabled in the 
overlapping regions.
• Align Pattern
The align pattern makes the 
overlaps more visible and helps 
adjust the physical position of the 
projectors in the array.
The size of the align pattern is 
controlled by the Blend Width 
group of settings.

Segmentation
Segmentation can be used if the same image is fed into each projector.
• If Segmentation is Off, every projector in the array will display the whole image.
• If this setting is On, each projector will display its own segment only.
Set to Off if you have external software that handles segmentation.
