NAME
SoShuttle -
The SoShuttle class is used to oscillate between two translations.
A smooth transition between translation0 and translation1 is created using a cosine function. In the beginning of the cycle, translation0
is used. Halfway through the cycle, the resulting translation equals translation1, and at the end of the cycle, we're at translation0
again.
SYNOPSIS
#include <Inventor/nodes/SoShuttle.h>
Inherits SoTranslation.

A smooth transition between translation0 and translation1 is created using a cosine function. In the beginning of the cycle, translation0
is used. Halfway through the cycle, the resulting translation equals translation1, and at the end of the cycle, we're at translation0
again.

Member Function Documentation
SoType SoShuttle::getClassTypeId (void) [static]
This static method returns the SoType object associated with objects of this class.
Reimplemented from SoTranslation.
SoType SoShuttle::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 SoTranslation.
const SoFieldData ** SoShuttle::getFieldDataPtr (void) [static], [protected]
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Reimplemented from SoTranslation.
const SoFieldData * SoShuttle::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 SoTranslation.
void SoShuttle::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 SoTranslation.
void SoShuttle::write (SoWriteAction *action) [virtual]
Action method for SoWriteAction.
Writes out a node object, and any connected nodes, engines etc, if necessary.
Reimplemented from SoNode.
Member Data Documentation
SoSFVec3f SoShuttle::translation0
Translation at the start and end of the cycle. Default value is (0, 0, 0).
SoSFVec3f SoShuttle::translation1
Translation at the middle of the cycle. Default value is (0, 0, 0).
SoSFFloat SoShuttle::speed
Number of cycles per second. Default value is 1.
SoSFBool SoShuttle::on
Toggles animation on or off. Defauls to TRUE.
