PositionVector NBNodeShapeComputer::computeNodeShapeSmall ( )

private

Computes the node geometry using normals.

In the case the other method does not work, this method computes the geometry of a node by adding points to the polygon which are computed by building the normals of participating edges' geometry boundaries (cw/ccw) at the node's height (the length of the edge the edge would cross the node point).

Note: This usually gives a very small node shape, appropriate for dead-ends or turn-around-only situations

private

Joins edges and computes ccw/cw boundaries.

This methods joins edges which are in marked as being "same" in the means as given by joinSameDirectionEdges. The result (list of so-to-say "directions" is returned; additionally, the boundaries of these directions are stored in ccwBoundary/cwBoundary.

	)

private

Joins edges and computes ccw/cw boundaries.

This method goes through all edges and stores each edge's ccw and cw boundary in geomsCCW/geomsCW. This boundary is extrapolated by 100m at the node's position. In addition, "same" is filled so that this map contains a list of all edges within the value-vector which direction at the node differs less than 1 from the key-edge's direction.
