Description

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).

Fields

SoSFShort numElements1

SoSFShort numElements2

SoSFShort numElements3
Number of elements in each of the three array dimensions.

SoSFVec3f separation1

SoSFVec3f separation2

SoSFVec3f separation3
Separation vector in each of the three array dimensions.

SoSFEnum origin
Defines the base point from which copies are distributed.

Methods

SoArray()
Creates an array node with default settings.

static SoType getClassTypeId()
Returns type identifier for this class.

Action Behavior

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction
Traverses all children for each array element, saving and restoring state before and after each traversal.

SoSearchAction
Traverses all children once, setting the inherited switch value to SO_SWITCH_ALL first.

File Format/Defaults

Array {
numElements1	1
numElements2	1
numElements3	1
separation1	1 0 0
separation2	0 1 0
separation3	0 0 1
origin	FIRST
}
