 Computes step value to construct point-line. The step depends on the local curvature of the intersection line computed in thePOn2S. theTgMagnitude is the magnitude of tangent vector to the intersection line (in the point thePOn2S). Computed step is always in the range [theStepMin, theStepMax]. Returns FALSE if the step cannot be computed. In this case, its value will not be changed. More...

 Compares distances from theMidPt to every quadrics with theMaxDeflection (maximal distance of two ones is taken into account). Returns the result of this comparison: -1 - small distance, +1 - big distance, 0 - Dist == theMaxDeflection. Comparisons are done with internal tolerances. More...

 Returns radius of a circle obtained by intersection the quadric with a plane goes through thePnt3d perpendicular to the quadric axis. This radius is computed for both quadrics and minimal value is returned. This check is made for cone and sphere only. More...

 Corrects the U-parameter of an end point (first or last) of the line if this end point is a pole. The line must contain at least 3 points. This is made for cone and sphere only. More...

◆ CheckDeflection()

Standard_Integer IntPatch_ALineToWLine::CheckDeflection ( const gp_XYZ theMidPt,
const Standard_Real  theMaxDeflection 
) const
protected

Compares distances from theMidPt to every quadrics with theMaxDeflection (maximal distance of two ones is taken into account). Returns the result of this comparison: -1 - small distance, +1 - big distance, 0 - Dist == theMaxDeflection. Comparisons are done with internal tolerances.

◆ CorrectEndPoint()

void IntPatch_ALineToWLine::CorrectEndPoint ( Handle< IntSurf_LineOn2S > &  theLine,
const Standard_Integer  theIndex 
) const
protected

Corrects the U-parameter of an end point (first or last) of the line if this end point is a pole. The line must contain at least 3 points. This is made for cone and sphere only.

◆ GetSectionRadius()

Standard_Real IntPatch_ALineToWLine::GetSectionRadius ( const gp_Pnt thePnt3d) const
protected

Returns radius of a circle obtained by intersection the quadric with a plane goes through thePnt3d perpendicular to the quadric axis. This radius is computed for both quadrics and minimal value is returned. This check is made for cone and sphere only.

◆ MakeWLine() [1/2]

void IntPatch_ALineToWLine::MakeWLine ( const Handle< IntPatch_ALine > &  aline,
IntPatch_SequenceOfLine theLines 
) const

Converts aline to the set of Walking-lines and adds them in theLines.
