uvFractionToPointAndTangents Method

Convert fractional u and v coordinates to surface point and in-surface tangent directions.

  • The vectors are expected to be non-zero tangents which can be crossed to get a normal.
  • Hence they are not necessarily (a) partial derivatives or (b) Frenet vectors.

uvFractionToPointAndTangents(uFraction: number, vFraction: number, result?: Plane3dByOriginAndVectors): Plane3dByOriginAndVectors

Parameter Type Description
