    • transform

      public void transform(SbMatrix matrix)
      Transforms the plane by the given matrix.

    • getDistance

      public float getDistance(SbVec3f point)

    • offset

      public void offset(float d)
      Offset a plane by a given distance.

    • intersect

      public SbVec3f intersect(SbLine l)
      Intersect line and plane, returning true if there is an intersection, false if line is parallel to plane.

    • getDistanceFromOrigin

      public float getDistanceFromOrigin()
      Returns distance from origin to plane.

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • getNormal

      public SbVec3f getNormal()
      Returns normal vector to plane.

    • isInHalfSpace

      public boolean isInHalfSpace(SbVec3f point)
      Returns true if the given point is within the half-space defined by the plane.
