Detailed Description

The SoVRMLPositionInterpolator class is used to interpolate 3D points.

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:

PositionInterpolator {
  eventIn      SFFloat set_fraction        # (-,)
  exposedField MFFloat key           []    # (-,)
  exposedField MFVec3f keyValue      []    # (-,)
  eventOut     SFVec3f value_changed
}

The PositionInterpolator node linearly interpolates among a list of 3D vectors. The keyValue field shall contain exactly as many values as in the key field. 4.6.8, Interpolator nodes (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.8), contains a more detailed discussion of interpolators.

Constructor & Destructor Documentation

SoVRMLPositionInterpolator::SoVRMLPositionInterpolator ( void )

Constructor.

SoVRMLPositionInterpolator::~SoVRMLPositionInterpolator ( )

protectedvirtual

Destructor.

Member Function Documentation

SoType SoVRMLPositionInterpolator::getClassTypeId ( void )

static

\ This static method returns the SoType object associated with \ objects of this class. \

SoType SoVRMLPositionInterpolator::getTypeId ( void ) const

virtual

Returns the type identification of an object derived from a \ class inheriting SoBase. This is used for runtime type checking and \ "downward" casting. \

Reimplemented from SoVRMLInterpolator.

const SoFieldData ** SoVRMLPositionInterpolator::getFieldDataPtr ( void )

staticprotected

\ This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. \ \ Returns the SoFieldData class which holds information about fields \ in this node. \

const SoFieldData * SoVRMLPositionInterpolator::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 * SoVRMLPositionInterpolator::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.

void SoVRMLPositionInterpolator::initClass ( void )

static

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Member Data Documentation

SoMFVec3f SoVRMLPositionInterpolator::keyValue

The keyValue vector.

SoEngineOutput SoVRMLPositionInterpolator::value_changed

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

The documentation for this class was generated from the following files:
