Member Function Documentation

IsFirst()

Bool IsFirst

(

)

Check if the polygon ID is the first occurrence in the array.

Note

Useful to know which polygons form an N-gon.

Returns

true if the polygon ID is the first occurrence in the array, otherwise false.

IsSegmentEnd()

Bool IsSegmentEnd

(

)

Checks if it is the last edge in the segment.

Returns

true if it is the last edge in the segment, otherwise false.

ID()

Int32 ID

(

)

Gets the polygon ID.

Returns

The polygon ID.

State()

Int32 State

(

)

Gets the edge state.

Returns

The edge as a bit, or 0 if the polygon has no edge on the outer/inner of the N-gon.

Edge()

Int32 Edge

(

)

Gets the edge of the polygon.

Returns

The edge of the polygon, or NOTOK for no edge.

EdgeIndex()

Int32 EdgeIndex

(

)

Gets the edge index.

Returns

The edge index (4*polygon ID + edge).

GetEdge()

void GetEdge	(	const CPolygon *	vadr,
		Int32 &	p1,
		Int32 &	p2
	)

Assigns to p1 and p2 the point IDs for the edge or NOTINDEX if it is not an N-gon edge.

Parameters

[in]	vadr	The polygon array. The caller owns the pointed array.
[out]	p1	Assigned the first point ID.
[out]	p2	Assigned the second point ID.
