Detailed Description

The SoComposeRotationFromTo class is used to compose rotations based on from and to vectors.

Member Function Documentation

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

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::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.

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.
