DESCRIPTION

This group node traverses its children, in order, several times, applying a different matrix each time. The matrices are stored in the multiple-value matrix field. Each matrix is concatenated to the current transformation matrix, and all of the children are traversed. This allows the user to put multiple copies of the same data in different locations easily and efficiently.

Traversing the Nth child sets the current switch value to N, for use with inherited switch values (see SoSwitch).

FIELDS

SoMFMatrix matrix

Set of matrices to apply to children.

METHODS

SoMultipleCopy()

Creates a multiple copy node with default settings.

static SoType getClassTypeId()

Returns type identifier for this class.

ACTION BEHAVIOR

SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction

Traverses all children for each matrix, saving and restoring state before and after each traversal.

SoSearchAction

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