◆ CSLib_DerivativeStatus

D1uIsNull : ||D1U|| <= Resolution.

D1vIsNull : ||D1V|| <= Resolution

D1IsNull : the first derivatives in the U and V parametric directions have null length : ||D1U|| <= Resolution and ||D1V|| <= Resolution

D1uD1vRatioIsNull : the first derivative in the U direction has null length by comparison with the derivative in the V direction ||D1U|| / ||D1V|| <= RealEpsilon

D1vD1uRatioIsNull : the first derivative in the V direction has null length by comparison with the derivative in the U direction ||D1V|| / ||D1U|| <= RealEpsilon

D1uIsParallelD1v : the angle between the derivatives in the U and V direction is null (tolerance criterion given as input data)
