Detailed DescriptionThe SoArray class is a group node for setting up regular arrays of subgraphs. SoArray presents a convenient way of duplicating a node (typically a shape node) or a complete subgraph in 1 to 3 dimensions. The child node or subgraph can only be translated by regular offsets for all dimensions. For more flexible functionality for duplication of geometry, see the SoMultipleCopy group node, which can do general transformations (including rotation and scaling) for its child. FILE FORMAT/DEFAULTS: Array {
origin FIRST
numElements1 1
numElements2 1
numElements3 1
separation1 1 0 0
separation2 0 1 0
separation3 0 0 1
}

Member Function Documentation
SoType SoArray::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
}
else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
SoGroup * group = (SoGroup *)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 * SoArray::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 SoArray::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 SoArray::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action. Reimplemented from SoGroup. References SoGroup::doAction(), SoAction::getState(), numElements1, numElements2, numElements3, origin, SoState::pop(), SoState::push(), separation1, separation2, and separation3. Referenced by audioRender(), callback(), getPrimitiveCount(), GLRender(), and pick().
void SoArray::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. References doAction().
void SoArray::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. References doAction().
void SoArray::pick (SoPickAction * action) [virtual]Action method for SoPickAction. Does common processing for SoPickAction action instances. Reimplemented from SoGroup. References doAction().
void SoArray::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. References SbXfBox3f::extendBy(), SoGroup::getBoundingBox(), SoGetBoundingBoxAction::getCenter(), SoAction::getState(), SoGetBoundingBoxAction::getXfBoundingBox(), SbMatrix::identity(), SoGetBoundingBoxAction::isCenterSet(), SbBox3f::isEmpty(), SbBox3f::makeEmpty(), numElements1, numElements2, numElements3, origin, SoState::pop(), SoDebugError::postInfo(), SoState::push(), SoGetBoundingBoxAction::resetCenter(), separation1, separation2, separation3, SoGetBoundingBoxAction::setCenter(), SbXfBox3f::setTransform(), SbMatrix::setTranslate(), and SbXfBox3f::transform().
void SoArray::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. References SoGroup::handleEvent(), and SoNode::handleEvent().
void SoArray::getMatrix (SoGetMatrixAction * action) [virtual]Action method for SoGetMatrixAction. Updates action by accumulating with the transformation matrix of this node (if any). Reimplemented from SoGroup. References SoGroup::getMatrix().
void SoArray::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. See also SoSearchAction Reimplemented from SoGroup. References SoAction::getState(), SoState::pop(), SoState::push(), and SoGroup::search().
void SoArray::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. References doAction().
void SoArray::audioRender (SoAudioRenderAction * action) [virtual]Action method for SoAudioRenderAction. Does common processing for SoAudioRenderAction action instances. Reimplemented from SoGroup. References doAction().
