PositionInterpolator node

PositionInterpolator {
  SFFloat set_fraction 0
  SFVec3f value_changed 0 0 0
  MFFloat key []
  MFVec3f keyValue []
}

This interpolator is used to interpolate 3D coordinates (3 float values).

Note:
Do not mistake with CoordinateInterpolator which has its value_changed field typed MFVec3f.
See Interpolators for a detailed explanation on how interpolators work and when to use them.

SFFloat set_fraction 0:
Change this set_fraction field (between 0 to 1) to make the interpolator compute a new value.
Value usually routed from the TimeSensor.fraction_changed field. See Interpolators.

SFVec3f value_changed 0 0 0:
When a new coordinate is computed from the PositionInterpolator, it is sent to the value_changed field.

MFFloat key []:
List of float values between 0 and 1. See Interpolators.

MFVec3f keyValue []:
Contains a coordinate (3 float values) for each value of the key list.
