Method Detail

reset

public void reset()

Reset this workshop to its initial state from which computations can start.

Overrides:

reset in class PjWorkshop

ok

public void ok()

Accept the current state of the geometry and close the workshop.

Overrides:

ok in class PjWorkshop

splitAlongMarkedEdges

public static boolean splitAlongMarkedEdges(PgElementSet geom)

Destroy neighbourhood information along marked edges of an element set. Edges are defined as marked if both end points are selected.

Method first disconnects the element neighbourhood and then invokes PwCleanMesh#makeManifold(PgElementSet) to duplicate vertices and fully separate the geometry along the marked polygons.

splitAlongPolygon

public static boolean splitAlongPolygon(PgElementSet geom,
                                        PiVector polygon,
                                        PiVector[] newNeighbour)

Destroy neighbourhood informations along a polygon upon a PgElementSet in a given neighbourhood PiVector[]. The PgElementSet itself should still have correct neighbourhood informations.

joinAlongPolygon

public static boolean joinAlongPolygon(PgElementSet geom,
                                       PiVector polygon,
                                       PiVector[] newNeighbour)

Glue neighbourhood informations along a polygon upon a PgElementSet in a given neighbourhood PiVector[]. The PgElementSet itself should still have correct neighbourhood informations.

getElementStrips

public static PiVector[] getElementStrips(PgElementSet geom,
                                          int startIndex,
                                          int endIndex)

Get a set of different element strips between two given elements.

getElementStrips

public static PgPolygonSet getElementStrips(PgElementSet geom)

makeBndPolygonLoop

public static void makeBndPolygonLoop(PgElementSet geom)

makeBndPolygonLoopWithoutEnds

public static void makeBndPolygonLoopWithoutEnds(PgElementSet geom)
