white_dune 0.29beta996 (Development branch)
06-28-2008
white_dune is a graphical VRML97 editor, simple NURBS/Superformula 3D modeller and animation tool. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). It has support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create and display VRML97 files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.

SoVRMLColorInterpolator(3) Coin SoVRMLColorInterpolator(3) NAME
SoVRMLColorInterpolator - The SoVRMLColorInterpolator class is used to interpolate color values. 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/SoVRMLColorInterpolator.h> Inherits SoVRMLInterpolator. Public Member Functions virtual SoType getTypeId (void) const virtual const SoEngineOutputData * getOutputData (void) const SoVRMLColorInterpolator (void) Static Public Member Functions static SoType getClassTypeId (void) static void * createInstance (void) static void initClass (void) Public Attributes SoMFColor keyValue SoEngineOutput value_changed Protected Member Functions virtual const SoFieldData * getFieldData (void) const virtual ~SoVRMLColorInterpolator () Static Protected Member Functions static const SoFieldData ** getFieldDataPtr (void) static const SoEngineOutputData ** getOutputDataPtr (void) Detailed Description The SoVRMLColorInterpolator class is used to interpolate color values. 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: ColorInterpolator { eventIn SFFloat set_fraction # (-inf, inf) exposedField MFFloat key [] # (-inf, inf) exposedField MFColor keyValue [] # [0,1] eventOut SFColor value_changed }.fi This node interpolates among a list of MFColor key values to produce an SFColor (RGB) value_changed event. The number of colours in the keyValue field shall be equal to the number of keyframes in the key field. The keyValue field and value_changed events are defined in RGB colour space. A linear interpolation using the value of set_fraction as input is performed in HSV space (see http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/bibliography.html#[FOLE] for description of RGB and HSV colour spaces). The results are undefined when interpolating between two consecutive keys with complementary hues. 4.6.8, Interpolator nodes (http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.8), contains a detailed discussion of interpolators. Constructor &; Destructor Documentation SoVRMLColorInterpolator::SoVRMLColorInterpolator (void) Constructor. SoVRMLColorInterpolator::~SoVRMLColorInterpolator () [protected], [virtual] Destructor. Member Function Documentation SoType SoVRMLColorInterpolator::getClassTypeId (void) [static] This static method returns the SoType object associated with objects of this class. Reimplemented from SoVRMLInterpolator. SoType SoVRMLColorInterpolator::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 ** SoVRMLColorInterpolator::getFieldDataPtr (void) [static], [protected] Returns the SoFieldData class which holds information about inputs in this engine. Reimplemented from SoVRMLInterpolator. const SoFieldData * SoVRMLColorInterpolator::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 ** SoVRMLColorInterpolator::getOutputDataPtr (void) [static], [protected] Returns the SoEngineOutputData class which holds information about the outputs in this engine. Reimplemented from SoVRMLInterpolator. const SoEngineOutputData * SoVRMLColorInterpolator::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 SoVRMLColorInterpolator::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 SoMFColor SoVRMLColorInterpolator::keyValue The color values. SoEngineOutput SoVRMLColorInterpolator::value_changed The eventOut color. Author Generated automatically by Doxygen for Coin from the source code.
