ScalarDihedralAngleGetEvaluator Method

Gets an evaluator that can be used to find the value of this scalar function at a given JulianDate.

Gets an evaluator that can be used to find the scalar representing the angle between two vectors measured about a given axis. The evaluator returns a Motion<double> at the given JulianDate. If the given vectors provide derivatives, the first and second derivative of dihedral angle are provided except where they are undefined. If either vector is zero or colinear with the dihedral axis, the dihedral angle is assumed to be zero and no derivatives are provided.
