white_dune 0.29beta946 (Development branch)
05-16-2008
white_dune is a graphical VRML97 editor, simpleNURBS/Superformula 3D modeller and animation tool.VRML97 (Virtual Reality Modeling Language) is theISO standard for displaying 3D data over the Webvia browser plugins ("HTML for realtime 3D"). Ithas support for animation, real-time interaction,and multimedia (images, movies, and sounds).white_dune can read, create and display VRML97files and let the user change thescenegraph/fields. It also has support forstereoscopic view via "quadbuffer"-capable stereovisuals, and support for 3D input devices like ajoystick, spaceball, or magnetic tracker.License: GNU General Public License (GPL)Changes:|

SoVRMLPositionInterpolator(3) Coin SoVRMLPositionInterpolator(3) NAME
SoVRMLPositionInterpolator - 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: SYNOPSIS
#include <Inventor/VRMLnodes/SoVRMLPositionInterpolator.h> Inherits SoVRMLInterpolator. Public Member Functions virtual SoType getTypeId (void) const virtual const SoEngineOutputData * getOutputData (void) const SoVRMLPositionInterpolator (void) Static Public Member Functions static SoType getClassTypeId (void) static void * createInstance (void) static void initClass (void) Public Attributes SoMFVec3f keyValue SoEngineOutput value_changed Protected Member Functions virtual const SoFieldData * getFieldData (void) const virtual ~SoVRMLPositionInterpolator () Static Protected Member Functions static const SoFieldData ** getFieldDataPtr (void) static const SoEngineOutputData ** getOutputDataPtr (void) 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 }.fi 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/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.8), contains a more detailed discussion of interpolators. Constructor &; Destructor Documentation SoVRMLPositionInterpolator::SoVRMLPositionInterpolator (void) Constructor. SoVRMLPositionInterpolator::~SoVRMLPositionInterpolator () [protected], [virtual] Destructor. Member Function Documentation SoType SoVRMLPositionInterpolator::getClassTypeId (void) [static] This static method returns the SoType object associated with objects of this class. Reimplemented from SoVRMLInterpolator. SoType SoVRMLPositionInterpolator::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 ** SoVRMLPositionInterpolator::getFieldDataPtr (void) [static], [protected] Returns the SoFieldData class which holds information about inputs in this engine. Reimplemented from SoVRMLInterpolator. const SoFieldData * SoVRMLPositionInterpolator::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 SoVRMLInterpolator. const SoEngineOutputData ** SoVRMLPositionInterpolator::getOutputDataPtr (void) [static], [protected] Returns the SoEngineOutputData class which holds information about the outputs in this engine. 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. Reimplemented from SoVRMLInterpolator. 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.
