Method Detail

cloneV

public MeshCapper.CapVertex cloneV()

sort

public MeshCapper.CapVertex sort(MeshCapper.CapVertex[] vs)

Generate qnext links based on scanning Y large to Y small and if Y1==Y2, then X small to large

Parameters:

vs -

Returns:

null if there are two identical points (edge crossings)

compare

public int compare(MeshCapper.CapVertex v1,
                   MeshCapper.CapVertex v2)

Specified by:

compare in interface java.util.Comparator<MeshCapper.CapVertex>

interpolateX

protected float interpolateX(MeshCapper.CapVertex v1,
                             MeshCapper.CapVertex v2)

Get interpolated x for the scan line intersection with an edge. This method is used both in finding the last point for a split and for checking winding on same-side addition. determine

Parameters:

v1 -

v2 -

Returns:

x

link

protected void link(MeshCapper.CapVertex v)

Link this vertex with v or remove it from the chain.

Parameters:

v - null to remove

clear

protected void clear()

Free all links.

dumpRegion

private java.lang.String dumpRegion()

for debugging

Returns:

listing of vertices currently in a region

toString

public java.lang.String toString()

Description copied from class: javajs.util.T3

Returns a string that contains the values of this Tuple3f. The form is (x,y,z).

Overrides:

toString in class javajs.util.T3

Returns:

the String representation
