Member Function Documentation
- SoType SoComposeRotationFromTo::getClassTypeId (void) [static]
- This static method returns the SoType object associated with objects of this class.
- Reimplemented from SoEngine.
- SoType SoComposeRotationFromTo::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. - Implements SoBase.
- const SoFieldData ** SoComposeRotationFromTo::getInputDataPtr (void)
- [static, protected]
Returns the SoFieldData class which holds information about inputs in this engine. - Reimplemented from SoEngine.
- const SoEngineOutputData ** SoComposeRotationFromTo::getOutputDataPtr
- (void) [static, protected] Returns the SoEngineOutputData class which holds information about the outputs in this engine.
- Reimplemented from SoEngine.
- const SoFieldData * SoComposeRotationFromTo::getFieldData (void) const
- [virtual]
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. - Reimplemented from SoFieldContainer.
- const SoEngineOutputData * SoComposeRotationFromTo::getOutputData (void)
- const [virtual]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. - Implements SoEngine.
- static void SoComposeRotationFromTo::initClass (void) [static]
- Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
- Reimplemented from SoEngine.
- Referenced by SoEngine::initClasses().
Member Data Documentation
- SoMFVec3f SoComposeRotationFromTo::from
- Set of input vectors to rotate from.
- SoMFVec3f SoComposeRotationFromTo::to
- Set of input vectors to rotate to.
- SoEngineOutput SoComposeRotationFromTo::rotation
- (SoMFRotation) Set of output rotations, where each element is the rotation you need to apply to the from vector (of the same index) to make it point in the to direction.
