Using Replicators in 3D Space

Two of the replicator pattern styles available 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 tab. Box and Sphere replicators build a pattern of elements in 3D space. Whereas the 2D Rectangle and Circle replicator shapes have columns (in the Y plane) and rows (in the X plane), Box and Sphere have an additional Ranks parameter, which adds depth to the replicator.

The Line and Wave replicator shapes, on the other hand, 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 in order to be pulled out of the X and Y planes by a behavior.

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.

Certain operations, as well as the application of certain filters or a mask, will rasterize a 3D group. For more information on rasterization, see About Rasterization.

Tip: When working with elements in 3D, you can quickly 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 tab (or Timeline layers list), click the Isolate button.

    Figure. Layers tab inset showing 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.
