The NormalInterpolator node interpolates among a list of normal vector sets specified by the keyValue field to produce an MFVec3f value_changed event.
The output vector, value_changed, shall be a set of normalized vectors.
Values in the keyValue field shall be of unit length. The number of normals in the keyValue field shall be an integer multiple of the number of key frames in the key field. That integer multiple defines how many normals will be contained in the value_changed events.
Normal interpolation shall be performed on the surface of the unit sphere. That is, the output values for a linear interpolation from a point P on the unit sphere to a point Q also on the unit sphere shall lie along the shortest arc (on the unit sphere) connecting points P and Q. Also, equally spaced input fractions shall result in arcs of equal length. The results are undefined if P and Q are diagonally opposite.
Examples:
H3DUniquePtr< MFVec3f > H3D::NormalInterpolator::keyValue |
H3DUniquePtr< MFValue > H3D::NormalInterpolator::value_changed |
