public class SbBox2s extends SbBasic
2D box class. 2D box which has planes parallel to the major axes and is specified by two points (specified with short integers) on a diagonal. This class is part of the standard Open Inventor datatype classes and is used as input and output to geometry operations.

    • SbBox2s

      public SbBox2s()
      Constructor for a 2D integer box. The box is initially empty.

    • SbBox2s

      public SbBox2s(SbVec2s _min, SbVec2s _max)
      Constructor for a 2D integer box. m_min and m_max are the corners of the diagonal that defines the box.

    • 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.

    • toArray

      public static SbBox2s[] toArray(long nativeArray, long length)

    • setBounds

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

    • hasArea

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

    • equals

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

    • setBounds

      public void setBounds(SbVec2s _min, SbVec2s _max)
      Sets the corners of the box.

    • extendBy

      public void extendBy(SbVec2s pt)
      Extends this box (if necessary) to contain the specified point.

    • getBounds

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

    • getMax

      public SbVec2s getMax()
      Returns the maximum point of the box.

    • intersection

      public SbBox2s intersection(SbBox2s box)
      Returns the intersection of the specified box with this box. Returned box is empty if there is no intersection.

    • intersect

      public boolean intersect(SbBox2s bb)
      Returns true if the specified box intersects this box.

    • extendBy

      public void extendBy(SbBox2s r)
      Extends this box (if necessary) to contain the specified box.

    • intersect

      public boolean intersect(SbVec2s pt)
      Returns true if the specified point intersects this box.

    • getSize

      public short[] getSize()
      Returns box size.

    • getAspectRatio

      public float getAspectRatio()
      Returns aspect ratio (ratio of width to height) of box.

    • getMinMax

      public SbVec2s[] getMinMax()
      Gets the corners of the box.

    • getMin

      public SbVec2s getMin()
      Returns the minimum point of the box.

    • getOrigin

      public short[] getOrigin()
      Returns origin (minimum point) of box.
