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.

		const Standard_Real	paraminf,
		const Standard_Real	paramsup,
		IntPatch_SequenceOfLine &	theLines
	)		const

Converts aline (limited by paraminf and paramsup) to the set of Walking-lines and adds them in theLines.
