Detailed Description
The SoMultipleCopy class redraws it's children multiple times at different transformations.
The SoMultipleCopy group node duplicates it's children nodes / subgraphs without using additional memory
resources.
It can do general transformations (translations, rotation and scaling) for it's children. Apart from
transformations, the appearance of it's children will be identical.

SoType SoMultipleCopy::getTypeId (void) const [virtual]
Returns the type identification of an object derived from a class inheriting SoBase. This is used for
run-time type checking and 'downward' casting. Usage example:
void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or
others: this method needs to be overridden in all subclasses. This is typically done as part of setting
up the full type system for extension classes, which is usually accomplished by using the pre-defined
macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and
SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses
for the various class groups.
Reimplemented from SoGroup.
const SoFieldData * SoMultipleCopy::getFieldData (void) const [protected], [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are
present, returns NULL.
Reimplemented from SoGroup.
SbBool SoMultipleCopy::affectsState (void) const [virtual]
Returns TRUE if the node could have any effect on the state during traversal.
If it returns FALSE, no data in the traversal-state will change from the pre-traversal state to the post-
traversal state. The SoSeparator node will for instance return FALSE, as it pushes and pops the state
before and after traversal of its children. All SoShape nodes will also return FALSE, as just pushing out
geometry data to the rendering engine won't affect the actual rendering state.
The default method returns TRUE, on a 'better safe than sorry' philosophy.
Reimplemented from SoNode.
void SoMultipleCopy::doAction (SoAction *action) [virtual]
This function performs the typical operation of a node for any action.
Reimplemented from SoGroup.
void SoMultipleCopy::callback (SoCallbackAction *action) [virtual]
Action method for SoCallbackAction.
Simply updates the state according to how the node behaves for the render action, so the application
programmer can use the SoCallbackAction for extracting information about the scene graph.
Reimplemented from SoGroup.
void SoMultipleCopy::GLRender (SoGLRenderAction *action) [virtual]
Action method for the SoGLRenderAction.
This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants
to throw geometry primitives at OpenGL overrides this method.
Reimplemented from SoGroup.
void SoMultipleCopy::pick (SoPickAction *action) [virtual]
Action method for SoPickAction.
Does common processing for SoPickAction action instances.
Reimplemented from SoGroup.
void SoMultipleCopy::getBoundingBox (SoGetBoundingBoxAction *action) [virtual]
Action method for the SoGetBoundingBoxAction.
Calculates bounding box and center coordinates for node and modifies the values of the action to
encompass the bounding box for this node and to shift the center point for the scene more towards the one
for this node.
Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change
the relevant state variables.
Reimplemented from SoGroup.
void SoMultipleCopy::handleEvent (SoHandleEventAction *action) [virtual]
Action method for SoHandleEventAction.
Inspects the event data from action, and processes it if it is something which this node should react to.
Nodes influencing relevant state variables for how event handling is done also overrides this method.
Reimplemented from SoGroup.
void SoMultipleCopy::getMatrix (SoGetMatrixAction *action) [virtual]
Action method for SoGetMatrixAction.
Updates action by accumulating with the transformation matrix of this node (if any).
Reimplemented from SoGroup.
void SoMultipleCopy::search (SoSearchAction *action) [virtual]
Action method for SoSearchAction.
Compares the search criteria from the action to see if this node is a match. Searching is done by
matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the
search is not deemed successful for the node.

SoSearchAction
Reimplemented from SoGroup.
void SoMultipleCopy::getPrimitiveCount (SoGetPrimitiveCountAction *action) [virtual]
Action method for the SoGetPrimitiveCountAction.
Calculates the number of triangle, line segment and point primitives for the node and adds these to the
counters of the action.
Nodes influencing how geometry nodes calculates their primitive count also overrides this method to
change the relevant state variables.
Reimplemented from SoGroup.
void SoMultipleCopy::audioRender (SoAudioRenderAction *action) [virtual]
Action method for SoAudioRenderAction.
Does common processing for SoAudioRenderAction action instances.
Reimplemented from SoGroup.
Member Data Documentation
SoMFMatrix SoMultipleCopy::matrix
A set of geometry transformation matrices.
The number of duplicated redraws of the child geometry will be the same as the number of matrices
specified in this field. Ie, each duplication will be transformed according to a transformation matrix.
The default value of the field is to contain just a single identity matrix.
