Ops 12–4 • Squeeze & Tease Basic Operation Vision Operator’s Manual (v12.0 MD)
You may want to think of the 3D working area as a cube with a defined width (X-Axis), height
(Y-Axis), and depth (Z-Axis) (Figure 12.3).
Figure 12.3 3D Space
Note — The Z-Axis works somewhat differently than the other axes because it is the
equivalent of 400 screen widths in each direction. Images can be moved on the Z-Axis until they
become so small they disappear from view.
Screen and Image Location
You can manipulate images in different ways within 3D space to achieve creative results.
When working with images, keep in mind that 3D space extends beyond the visible area of the
screen. Images can be positioned and manipulated outside of the viewable area to create some
interesting effects.
The viewpoint is the point in space that the image is viewed from (Figure 12.4).
Figure 12.4 Screen and Image Locations in 3D Space
The visible area is the area within 3D space that can be seen from the viewpoint (Figure 12.5).
