Detailed Description

The class represents the Intersection phase of the Boolean Operations algorithm.
It performs the pairwise intersection of the sub-shapes of the arguments in the following order:

Vertex/Vertex;
Vertex/Edge;
Edge/Edge;
Vertex/Face;
Edge/Face;
Face/Face.

The results of intersection are stored into the Data Structure of the algorithm.

Additionally to the options provided by the parent class, the algorithm has the following options:

Section attributes - allows to customize the intersection of the faces (avoid approximation or building 2d curves);
Safe processing mode - allows to avoid modification of the input shapes during the operation (by default it is off);
Gluing options - allows to speed up the calculation on the special cases, in which some sub-shapes are coincide.

The algorithm returns the following Warning statuses:

BOPAlgo_AlertSelfInterferingShape - in case some of the argument shapes are self-interfering shapes;
BOPAlgo_AlertTooSmallEdge - in case some edges of the input shapes have no valid range;
BOPAlgo_AlertNotSplittableEdge - in case some edges of the input shapes has such a small valid range so it cannot be split;
BOPAlgo_AlertBadPositioning - in case the positioning of the input shapes leads to creation of small edges;
BOPAlgo_AlertIntersectionOfPairOfShapesFailed - in case intersection of some of the sub-shapes has failed;
BOPAlgo_AlertAcquiredSelfIntersection - in case some sub-shapes of the argument become connected through other shapes;
BOPAlgo_AlertBuildingPCurveFailed - in case building 2D curve for some of the edges on the faces has failed.

The algorithm returns the following Error alerts:

BOPAlgo_AlertTooFewArguments - in case there are no enough arguments to perform the operation;
BOPAlgo_AlertIntersectionFailed - in case some unexpected error occurred;
BOPAlgo_AlertNullInputShapes - in case some of the arguments are null shapes.
