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
}

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/documents/specifications/14772/V2.0/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/documents/specifications/14772/V2.0/part1/concepts.html#4.6.8), contains a detailed discussion of interpolators.

Member Function Documentation

◆ getClassTypeId()

SoType SoVRMLColorInterpolator::getClassTypeId ( void )

static

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

◆ getFieldData()

const SoFieldData * SoVRMLColorInterpolator::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.

◆ getFieldDataPtr()

const SoFieldData ** SoVRMLColorInterpolator::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.

◆ getOutputData()

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.

◆ getTypeId()

SoType SoVRMLColorInterpolator::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.

◆ initClass()

static

Member Data Documentation

◆ keyValue

SoMFColor SoVRMLColorInterpolator::keyValue

The color values.

◆ value_changed

SoEngineOutput SoVRMLColorInterpolator::value_changed
