Constructor Detail

Plane

public Plane(Vector3d normal,
             double dist)

Constructor. Creates a new plane defined by its normal vector and the distance to the origin.

Parameters:

normal - plane normal

dist - distance from origin

Method Detail

createFromPoints

public static Plane createFromPoints(Vector3d a,
                                     Vector3d b,
                                     Vector3d c)

Creates a plane defined by the the specified points.

Parameters:

a - first point

b - second point

c - third point

Returns:

a plane

clone

public Plane clone()

Overrides:

clone in class java.lang.Object

flip

public void flip()

Flips this plane.

splitPolygon

public void splitPolygon(Polygon polygon,
                         java.util.List<Polygon> coplanarFront,
                         java.util.List<Polygon> coplanarBack,
                         java.util.List<Polygon> front,
                         java.util.List<Polygon> back)

Splits a Polygon by this plane if needed. After that it puts the polygons or the polygon fragments in the appropriate lists (front, back). Coplanar polygons go into either coplanarFront, coplanarBack depending on their orientation with respect to this plane. Polygons in front or back of this plane go into either front or back.

Parameters:

polygon - polygon to split

coplanarFront - "coplanar front" polygons

coplanarBack - "coplanar back" polygons

front - front polygons

back - back polgons

getDebugger

public static IPolygonDebugger getDebugger()

setDebugger

public static void setDebugger(IPolygonDebugger debugger)

isUseDebugger

public static boolean isUseDebugger()

setUseDebugger

public static void setUseDebugger(boolean useDebugger)
