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 }
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.
SoVRMLColorInterpolator::SoVRMLColorInterpolator | ( | void | ) |
Constructor.
SoVRMLColorInterpolator::~SoVRMLColorInterpolator | ( | ) | [protected, virtual] |
Destructor.
const SoEngineOutputData ** SoVRMLColorInterpolator::getOutputDataPtr | ( | void | ) | [static, protected] |
Returns the SoEngineOutputData class which holds information about the outputs in this engine.
Reimplemented from SoNodeEngine.
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.
Implements SoNodeEngine.
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.
The color values.
The eventOut color.
