 ChLineBezier (std::shared_ptr< ChBezierCurve > path)
 
 ChLineBezier (const std::string &filename)
 
 ChLineBezier (const ChLineBezier &source)
 
virtual ChLineBezierClone () const override
 "Virtual" copy constructor (covariant return type).
 
virtual Type GetClassType () const override
 Get the class type as an enum.
 
virtual void Set_closed (bool mc) override
 
virtual void Set_complexity (int mc) override
 
virtual ChAABB GetBoundingBox () const override
 Compute bounding in the frame of the Bezier curve knots.
 
virtual ChVector Evaluate (double U) const override
 Return a point on the line, given parametric coordinate U (in [0,1]).
 
virtual void ArchiveOut (ChArchiveOut &marchive) override
 Method to allow serialization of transient data to archives.
 
virtual void ArchiveIn (ChArchiveIn &marchive) override
 Method to allow de-serialization of transient data from archives.
 
- Public Member Functions inherited from chrono::geometry::ChLine
 ChLine (const ChLine &source)
 
virtual ChVector GetTangent (double parU) const
 Return the tangent unit vector at the parametric coordinate U (in [0,1]). More...
 
virtual bool Get_closed () const
 Tell if the curve is closed.
 
virtual int Get_complexity () const
 Tell the complexity.
 
virtual int GetManifoldDimension () const override
 This is a line.
 
bool FindNearestLinePoint (ChVector<> &point, double &resU, double approxU, double tol) const
 Find the parameter resU for the nearest point on curve to "point".
 
virtual double Length (int sampling) const
 Returns curve length. Typical sampling 1..5 (1 already gives correct result with degree1 curves)
 
virtual ChVector GetEndA () const
 Return the start point of the line. More...
 
virtual ChVector GetEndB () const
 Return the end point of the line. More...
 
double CurveCurveDist (ChLine *compline, int samples) const
 Returns adimensional information on "how much" this curve is similar to another in its overall shape (does not matter parametrization or start point). More...
 
double CurveSegmentDist (ChLine *complinesegm, int samples) const
 Same as before, but returns "how near" is complinesegm to whatever segment of this line (does not matter the percentual of line). More...
 
double CurveCurveDistMax (ChLine *compline, int samples) const
 Same as above, but instead of making average of the distances, these functions return the maximum of the distances...
 
double CurveSegmentDistMax (ChLine *complinesegm, int samples) const
 
virtual bool DrawPostscript (ChFile_ps *mfle, int markpoints, int bezier_interpolate)
 Draw into the current graph viewport of a ChFile_ps file.

void InflateBoundingBox (ChAABB &bbox) const
 Enlarge the given existing bounding box with the bounding box of this object.
 
virtual double GetBoundingSphereRadius () const
 Returns the radius of a bounding sphere for this geometry. More...
 
virtual ChVector Baricenter () const
 Compute center of mass.
 
virtual void Update ()
 Generic update of internal data.
