π¦ SoMultipleCopy π¦
okay bestie, buckle up β this is the Coin manual, section 3, and the star of the show is a node class that redraws its children multiple times at different transformations. yes, multiple. it's literally in the name. it's giving "one kid, forty outfit changes" energy and honestly? we're obsessed π
π NAME π
SoMultipleCopy β the class that redraws its children multiple times, each at a different transformation. that's it, that's the whole vibe check. π

π¦ DETAILED DESCRIPTION π¦
okay so bestie, picture this: the SoMultipleCopy class is that girl who redraws her children multiple times at different transformations. iconic behavior honestly.
It's a group node, and what it does is duplicate its child nodes / subgraphs β but without using additional memory resources. yes really, no cap, she's efficient like that π
She can do general transformations (translations, rotation and scaling) for her children. Apart from transformations, the appearance of her children will be identical β same fit, different angles, periodt.

SoMultipleCopy::SoMultipleCopy(void)β Constructor. she's being born πSoMultipleCopy::~SoMultipleCopy()[protected],[virtual]β Destructor. she's leaving, and it's protected, so like, only her inner circle can do it π«Ά
π MEMBER FUNCTION DOCUMENTATION π
SoType SoMultipleCopy::getClassTypeId(void)[static]β this static method returns theSoTypeobject associated with objects of this class. her little ID card πSoType SoMultipleCopy::getTypeId(void) const[virtual]β Returns the type identification of an object derived from a class inheritingSoBase. This is used for runtime type checking and "downward" casting. Reimplemented fromSoGroup.const SoFieldData ** SoMultipleCopy::getFieldDataPtr(void)[static],[protected]β This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. So like... don't touch, bestie, it's not for you π Returns theSoFieldDataclass which holds information about fields in this node.const SoFieldData * SoMultipleCopy::getFieldData(void) const[protected],[virtual]β Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returnsNULL. (the "nothing here" energy π) Reimplemented fromSoGroup.SbBool SoMultipleCopy::affectsState(void) const[virtual]β ReturnsTRUEif the node could have any effect on the state during traversal. If it returnsFALSE, no data in the traversal state will change from the pre-traversal state to the post-traversal state. TheSoSeparatornode will for instance returnFALSE, as it pushes and pops the state before and after traversal of its children. AllSoShapenodes will also returnFALSE, as just pushing out geometry data to the rendering engine won't affect the actual rendering state. The default method returnsTRUE, on a "better safe than sorry" philosophy. honestly? relatable, she's just being careful π Reimplemented fromSoNode.void SoMultipleCopy::doAction(SoAction * action)[virtual]β This function performs the typical operation of a node for any action. the all-rounder β¨ Reimplemented fromSoGroup.void SoMultipleCopy::callback(SoCallbackAction * action)[virtual]β Action method forSoCallbackAction. Simply updates the state according to how the node behaves for the render action, so the application programmer can use theSoCallbackActionfor extracting information about the scene graph. Reimplemented fromSoGroup.void SoMultipleCopy::GLRender(SoGLRenderAction * action)[virtual]β Action method for theSoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. π₯ Reimplemented fromSoGroup.void SoMultipleCopy::pick(SoPickAction * action)[virtual]β Action method forSoPickAction. Does common processing forSoPickActionaction instances. Reimplemented fromSoGroup.void SoMultipleCopy::getBoundingBox(SoGetBoundingBoxAction * action)[virtual]β Action method for theSoGetBoundingBoxAction. 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 calculate their bounding box also override this method to change the relevant state variables. Reimplemented fromSoGroup.void SoMultipleCopy::handleEvent(SoHandleEventAction * action)[virtual]β Action method forSoHandleEventAction. Inspects the event data from action, and processes it if it is something which this node should react to. she said "is this about me? π" Nodes influencing relevant state variables for how event handling is done also override this method. Reimplemented fromSoGroup.void SoMultipleCopy::getMatrix(SoGetMatrixAction * action)[virtual]β Action method forSoGetMatrixAction. Updates action by accumulating with the transformation matrix of this node (if any). Reimplemented fromSoGroup.void SoMultipleCopy::search(SoSearchAction * action)[virtual]β Action method forSoSearchAction. 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 theSoSearchActionβ if any of the requested criteria is a miss, the search is not deemed successful for the node. it's giving "you must match ALL of my requirements, no exceptions" π See alsoSoSearchActionReimplemented fromSoGroup.
void SoMultipleCopy::getPrimitiveCount(SoGetPrimitiveCountAction * action)[virtual]β Action method for theSoGetPrimitiveCountAction. 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 calculate their primitive count also override this method to change the relevant state variables. Reimplemented fromSoGroup.void SoMultipleCopy::audioRender(SoAudioRenderAction * action)[virtual]β Action method forSoAudioRenderAction. Does common processing forSoAudioRenderActionaction instances. Reimplemented fromSoGroup.
π MEMBER DATA DOCUMENTATION π
SoMFMatrix SoMultipleCopy::matrix
A set of geometry transformation matrices. π
The number of duplicated redraws of the child geometry will be the same as the number of matrices specified in this field. I.e., each duplication will be transformed according to a transformation matrix.
The default value of the field is to contain just a single identity matrix. the classic "just me, unchanged, iconic" default β¨
