A rotator object produces duplicates or instances of its first sub object by rotating and/or translating the copies into regular rows and circles. If the second parameter object is one dimensional (a NURBS curve), the result is a sequence of objects. If the second sub object is two dimensional mesh, the result is an array of objects.

The following set of controls is available. The 'U direction' controls are applied for all kind of parameters. The V direction controls become relevant when the 2nd parameter is two dimensional. Both sets of controls work in a similar way.

Copy Method: The object duplicates can be either real objects or instances. Instancing saves some memory especially when the sample object is complex.

Angle: Defines how much a new duplicate is rotated from the previous duplicate around the current parameter object evaluation position.

Total Angle: The same as the previous one, but expressed as the total rotation for all duplicates.

Translation: Defines how much a new duplicate is moved along the 2nd parameter U/V dimension. The amount is measured in parameter space i.e. value 1 corresponds to full parameter length.

Total Translation: Amount of total translation from the sample object to the last copy/instance.

Count: Controls the amount of resulting objects (or object rows/columns in 2D case).
