Using Replicators in 3D Space
Two replicator pattern styles in the Shapes pop-up menu have 3D properties: Box and
Sphere. The Box and Sphere shape options are available only when the 3D checkbox is
selected in the Replicator Inspector. Box and Sphere replicators build a pattern of elements
in 3D space. The 2D Rectangle and Circle replicator shapes have columns (in the Y plane)
and rows (in the X plane), but Box and Sphere have an additional Ranks parameter, which
adds depth to the replicator.
Box replicator with 13 columns, 12 rows,
and 3 ranks
Sphere replicator with 14 columns, 14 rows,
and 5 ranks
Line and Wave replicator shapes have quasi-3D properties: Their start and end points can
be moved into Z space. In the following image, the Z Start Point (yellow end of the pattern)
is set to 20 and the Z End Point is –18 (red end of the pattern).
Although the Rectangle, Circle, Line, Wave, Image, and Geometry replicators have no
inherent 3D parameters, they can be moved and rotated in 3D space. Pattern elements
can also be pulled out of their plane when behaviors are applied. The replicator must be
a member of a 3D group to be pulled out of the X and Y planes by a behavior.
Using the Replicator
The following illustrations demonstrate replicator pattern elements pulled into Z space.
In the illustration on the left, the Burst replicator’s Z position is set to 0 and the white
circle’s Z position is set to 225. An “Attracted To” Simulation behavior is applied to the
replicator, with the white circle set as the target object. As the project plays, as shown in
the center illustration, the replicator elements move forward in Z space toward the
attractor. In the right illustration, the camera is rotated to look behind the replicator.
Under the behavior’s influence, the replicator elements move past their attractor element,
and return to their original position.
Tip: When working with elements in 3D, you can snap an object back to its original
orientation by using the Isolate command.
To isolate a group or layer
Do one of the following:
In the Layers list (or Timeline), click the Isolate button.
Inactive Isolate button
Control-click the layer or group, then choose Isolate from the shortcut menu.
Choose Object > Isolate.
Click the Isolate button again to return to your previous view.
Note: Clicking a camera’s Isolate button activates that camera’s view.
