Detailed Description
Group node that traverses multiple times, applying matrices.
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).
FILE FORMAT/DEFAULT
- MultipleCopy {
| matrix | 1 0 0 0 |
| 0 1 0 0 | |
| 0 0 1 0 | |
| 0 0 0 1 |
ACTION BEHAVIOR
- SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction
Traverses all children for each matrix, saving and restoring state before and after each traversal. Sets: SoSwitchElement
SoSearchAction
Traverses all children once, setting the inherited switch value to SO_SWITCH_ALL first.

Constructor & Destructor Documentation
| SoMultipleCopy::SoMultipleCopy | ( | ) |
Creates a multiple copy node with default settings.
Member Function Documentation
| virtual SbBool SoMultipleCopy::affectsState | ( | ) | const [virtual] |
Returns TRUE if a node has an effect on the state during traversal.
The default method returns TRUE. Node classes (such as SoSeparator) that isolate their effects from the rest of the graph override this method to return FALSE.

| static SoType SoMultipleCopy::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.

| virtual SoType SoMultipleCopy::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Reimplemented from SoGroup.
