Working in 3D Space
In order to maximize the features of the Squeeze & Tease option, it helps to have a basic
understanding of three-dimensional (3D) space (Figure 12.2). Three axes (X, Y, and Z) are used
to define 3D space. The position of an image on each of the three axes determines its location in
3D space.
• X — Refers to the horizontal (left-right) position of the image on the screen.
• Y — Refers to the vertical (up-down) position of the image on the screen.
• Z — Refers to the distance (forwards-backwards) of the image to the screen.

Image Location in 3D Space
The center point of the screen is the zero point. Each axis has a positive and negative region.
• Moving an image to the left of the center (or zero) point locates it in -X space.
• Moving an image to the right of the center point locates it in +X space.
• Moving an image below the center point locates it in -Y space.
• Moving an image above the center point locates it in +Y space.
• Moving an image closer to you locates it in -Z space.
• Moving an image away from you locates in it +Z space.
Position Coordinates
The 3D space you work with in this system has upper and lower limits. Position coordinates are
used to define an image location in 3D space and are shown as a unit measurement on the menus.
A change in position of 1.000 units is equal to a move of 1 full screen. For example, to move the
image two screens to the right, adjust the X-Axis value to 2.000.
Changing the location of an image in 3D space does not affect the size or shape of the image.
However, when an image is moved forward, it appears larger on the screen. When located at a
greater distance in 3D space, it appears smaller.
Position coordinates can be adjusted using the positioner or the knobs on the menu.
• You can move the image 144.000 full screen widths in either direction on the X-Axis.
• You can move the image 144.000 full screen heights in either direction on the Y-Axis.
• You can move the image 400.000 full screen widths in either direction on the Z-Axis.
