getNormalVector
public Vector3D getNormalVector()
- Points towars the outside part of the plane.
- Returns:
- the outer normal vector.
getLineIntersection
public Point3D getLineIntersection(StraightLine3D line)
- Compute intersection of a line with this plane. Uses algorithm 1 given
in:
http://local.wasp.uwa.edu.au/~pbourke/geometry/planeline/.
- Parameters:
line
- the line which intersects the plane
- Returns:
- the intersection point
projectPoint
public Point3D projectPoint(Point3D point)
projectVector
public Vector3D projectVector(Vector3D vect)
getPoint
public Point3D getPoint(double u,
double v)
getPointPosition
public Point2D getPointPosition(Point3D point)
clip
public Shape3D clip(Box3D box)
- Specified by:
clip
in interface Shape3D
contains
public boolean contains(Point3D point)
- Specified by:
contains
in interface Shape3D
getBoundingBox
public Box3D getBoundingBox()
- Specified by:
getBoundingBox
in interface Shape3D
getDistance
public double getDistance(Point3D point)
- Description copied from interface:
Shape3D
- Gets the distance of the shape to the given point, or the distance of
point to the frontier of the shape in the case of a plain shape.
- Specified by:
getDistance
in interface Shape3D
isBounded
public boolean isBounded()
- Description copied from interface:
Shape3D
- Returns true if the shape is bounded, that is if we can draw a finite
rectangle enclosing the shape. For example, a straight line or a parabola
are not bounded.
- Specified by:
isBounded
in interface Shape3D
isEmpty

- Specified by:
isEmpty
in interface Shape3D
transform
public Shape3D transform(AffineTransform3D trans)
- Specified by:
transform
in interface Shape3D
equals
public boolean equals(Object obj)
- Overrides:
equals
in class Object
