Detailed Description

Dtk_Curve is a geometrical entity representing a curve. It is an abstract class that cannot be instancied.
It has several utility methods :
.

• GetDomain allow you to get the whole definition domain for the curve.

  Dtk_ErrorStatus GetDomain(Dtk_Double64& outUmin,Dtk_Double64& outUmax) const;

• SetTrimmingParameters/GetTrimUMin/GetTrimUMax allow you to specify/get the used domain for the curve.

  Dtk_ErrorStatus SetTrimmingParameters(const Dtk_Double64& inUmin,const Dtk_Double64& inUmax);
  Dtk_Double64 GetTrimUMin() const;
  Dtk_Double64 GetTrimUMax() const;

• ToNurbs convert the curve into nurbs curve.
• ToPolyline convert the curve into polyline .
