CheckDeflection()

int IntPatch_ALineToWLine::CheckDeflection ( const gp_XYZ & theMidPt, const double 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 ( occ::handle< IntSurf_LineOn2S > & theLine, const int 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()

double 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.
