Detailed Description
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 key frames 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 [FOLEY] for description of RGB and HSV colour spaces). The results are undefined when interpolating between two consecutive keys with complementary hues.
Examples:
- Internal routes:
