Field Detail

EPSILON

public static double EPSILON

EPSILON is the tolerance used by splitPolygon(eu.mihosoft.vrl.v3d.Polygon, java.util.List, java.util.List, java.util.List, java.util.List) to decide if a point is on the plane. public static final double EPSILON = 0.00000001;

EPSILON_Point

public static double EPSILON_Point

XY_PLANE

public static final Plane XY_PLANE

XY plane.

XZ_PLANE

public static final Plane XZ_PLANE

XZ plane.

YZ_PLANE

public static final Plane YZ_PLANE

YZ plane.

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

Plane

public Plane(Vector3d normal,
             java.util.List<Vertex> vertices)

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(java.util.List<Vertex> vertices)

Creates a plane defined by the the specified points.

Parameters:

a - first point

b - second point

c - third point

Returns:

a plane

computeNormal

public static Vector3d computeNormal(java.util.List<Vertex> vertices)

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
