## Detailed Description

The SoVRMLOrientationInterpolator class is used to interpolate orientations.

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:

    OrientationInterpolator {
      eventIn      SFFloat    set_fraction      # (-,)
      exposedField MFFloat    key           []  # (-,)
      exposedField MFRotation keyValue      []  # [-1,1],(-,)
      eventOut     SFRotation value_changed
    }

The OrientationInterpolator node interpolates among a list of rotation values specified in the keyValue field. These rotations are absolute in object space and therefore are not cumulative. The keyValue field shall contain exactly as many rotations as there are keyframes in the key field. An orientation represents the final position of an object after a rotation has been applied. An OrientationInterpolator interpolates between two orientations by computing the shortest path on the unit sphere between the two orientations. The interpolation is linear in arc length along this path. The results are undefined if the two orientations are diagonally opposite. If two consecutive keyValue values exist such that the arc length between them is greater than , the interpolation will take place on the arc complement. For example, the interpolation between the orientations (0, 1, 0, 0) and (0, 1, 0, 5.0) is equivalent to the rotation between the orientations (0, 1, 0, 2) and (0, 1, 0, 5.0). A more detailed discussion of interpolators is contained in 4.6.8, Interpolator nodes (http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.8).

## Constructor & Destructor Documentation

SoVRMLOrientationInterpolator::SoVRMLOrientationInterpolator | ( | void |  | ) |

SoVRMLOrientationInterpolator::~SoVRMLOrientationInterpolator | ( | void |  | ) |
| protectedvirtual

Destructor.

## Member Function Documentation

SoType SoVRMLOrientationInterpolator::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 SoVRMLInterpolator.

const SoFieldData * SoVRMLOrientationInterpolator::getFieldData | ( | void |  | ) | const
| protectedvirtual

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns `NULL`.

Reimplemented from SoVRMLInterpolator.

const SoEngineOutputData * SoVRMLOrientationInterpolator::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.

Reimplemented from SoVRMLInterpolator.

## Member Data Documentation

SoMFRotation SoVRMLOrientationInterpolator::keyValue

The keyValue vector.

SoEngineOutput SoVRMLOrientationInterpolator::value_changed

The eventOut which is sent every time the interpolator has calculated a new value.
