Purpose

This group node traverses its children, in order, several times, creating a regular 3D array of copies of them. The number of copies in each of the three directions is specified by fields, as are the vectors used to separate the copies in each of the three dimensions.

For example, an SoArray node can be used to create a 2x3x4 array of copies of its children, where the separation vectors between adjacent copies in the three array dimensions are (1,2,3), (-4,-5,-6), and (7,8,9), respectively. The base point of the array can be set to one of several values, as described in the origin field.

Copies are traversed so that the first dimension cycles most quickly, followed by the second, and then the third. This order is important because SoArray sets the current switch value to N before traversing the children for the Nth time (for use with inherited switch values - see SoSwitch).

Separation1

name: separation1, type: Vector3, default: 1 0 0

Separation vector in the first array dimension.

Separation2

name: separation2, type: Vector3, default: 0 1 0

Separation vector in the second array dimension.

Origin

name: origin, type: Enum, default: FIRST

Defines the base point from which copies are distributed.

Values:

Title	Name	Description
First	FIRST	First copy is rendered at the current local origin; all other copies are distributed relative to it.
Center	CENTER	Copies are distributed relative to the center of the array.
Last	LAST	Last copy is rendered at the current local origin; all other copies are distributed relative to it.
