public class SbBox2d extends SbBasic
2D box class. 2D box which has planes parallel to the major axes and is specified by two points (specified in double precision) on a diagonal. This class is part of the standard Open Inventor datatype classes and is used as input and output to geometry operations.

    • isEmpty

      public boolean isEmpty()
      Returns true if the box is empty, and false otherwise. Note: Setting the box to all zeros does not make it "empty". Use the makeEmpty() method. (This method only returns true if the maximum X value is less than the minimum X value.)

    • makeEmpty

      public void makeEmpty()
      Makes an empty box.

    • setBounds

      public void setBounds(double xmin, double ymin, double xmax, double ymax)
      Sets the corners of the box.

    • toArray

      public static SbBox2d[] toArray(long nativeArray, long length)

    • equals

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

    • hasArea

      public boolean hasArea()
      Returns true if both dimensions of the box have positive size, and false otherwise.

    • getCenter

      public SbVec2d getCenter()
      Returns the center of the box.

    • setBounds

      public void setBounds(SbVec2d _min, SbVec2d _max)
      Sets the corners of the box.

    • getMax

    • getBounds

      public double[] getBounds()
      Gets the corners of the box.

    • intersect

      public boolean intersect(SbVec2d pt)
      Returns true if the specified point intersects this box.

    • intersection

      public SbBox2d intersection(SbBox2d box)
      Returns the intersection of the specified box with this box. Returned box is empty if there is no intersection.

    • extendBy

      public void extendBy(SbVec2d pt)
      Extends this box (if necessary) to contain the specified point .

    • extendBy

      public void extendBy(SbBox2d r)
      Extends this box (if necessary) to contain the specified box.

    • getMinMax

      public SbVec2d[] getMinMax()
      Gets the corners of the box.

    • getSize

      public double[] getSize()
      Gets box size.

    • getAspectRatio

    • getClosestPoint

      public SbVec2d getClosestPoint(SbVec2d point)
      Returns the closest point on the box to the given point. (Returns the point on the center of the Z face if passed the center.)

    • getMin

      Returns the minimum point of the box.

    • getOrigin

      public double[] getOrigin()
