◆ Get2DSamplingWithoutDegeneratedEdges()

bool UE::CADKernel::FTopologicalLoop::Get2DSamplingWithoutDegeneratedEdges ( TArray< FVector2d > & LoopSampling ) const

The idea is to remove degenerated edges of the loop i.e. where the surface is degenerated

so where projections on these area are hazardous
so where 2d curve computation based on hazardous projection is hazardous...
so where the sampling could be in self-intersecting
Returns
false if the loop is degenerated

◆ GetActiveEdges()

◆ Orient()

bool UE::CADKernel::FTopologicalLoop::Orient ( )

To check loop orientation, we check the orientation of the extremity points i.e. "o" points below

For these points, the slop is compute. If the slop is between 0 and 4, the loop at the point is well oriented otherwise not

The difficulties start when the slop is closed to 0 or 4 i.e.

-----o-----

| |

In this case, the orientation of the next segment is compare to the bounding box

The last very difficult case is a sharp case i.e. The slop is closed to 0 or 8, so it could be a pick in self intersecting. We try to recompute the slop a the closed point

| o—O | O
| / | /
| o => | o
| | | |

If the slop is still closed to 0 or 8, the point is "UndefinedOrientation" This case was found in the shape of char '1'

Returns: false if the orientation is doubtful

Reimplemented from UE::CADKernel::FEntity.

◆ Serialize()

virtual void UE::CADKernel::FTopologicalLoop::Serialize ( FCADKernelArchive & Ar )

inlineoverridevirtual

Serialization of a FEntity. Each class derived from FEntity has to override this method (and call the direct base class override method first) E.g. class FEntityXXX : public FEntityXX { virtual void Serialize(FCADKernelArchive& Ar) override { FEntityXX::Serialize(Ar); ... } }

Reimplemented from UE::CADKernel::FTopologicalEntity.

The Edge is split in two edges : Edge + NewEdge

Parameters

bNewEdgeIsFirst == true => StartVertex Connected to Edge, EndVertexConnected to NewEdge According to the direction of Edge, if bNewEdgeIsFirst == true, NewEdge is added in the loop after (EOrientation::Front) or before (EOrientation::Back)
