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/technicalinfo/specifications/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/technicalinfo/specifications/vrml97/part1/concepts.html#4.6.8>), contains a detailed discussion of interpolators.
