public class SbBox3i32 extends SbBasic
3D box class. 3D box which has planes parallel to the major axes and is specified by two points on a diagonal. This class is part of the standard Open Inventor datatype classes and is used as input and output to geometry operations (see SoGetBoundingBoxAction).

  • Method Details

    • setValue

      public SbBox3i32 setValue(int[] components, int startIndex)

    • setValue

      public void setValue(SbBox3i32 copyFrom)

    • setValue

      public SbBox3i32 setValue(int[] components)

    • getValue

      public int[] getValue()

    • getSpan

      public float[] getSpan(SbVec3f direction)
      Finds the span of a box along a specified direction. The span is the total distance the box occupies along a given direction. The total distance is returned in the form of a minimum and maximum distance from the origin of each of the corners of the box along the given direction. The difference between these two values is the span.

    • hasVolume

      public boolean hasVolume()
      Returns true if all three dimensions of the box have positive size, and false otherwise.

    • equals

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

    • toArray

      public static SbBox3i32[] toArray(long nativeArray, long length)

    • transform

      public void transform(SbMatrix m)
      Transforms box by matrix, enlarging box to contain result.

    • getVolume

      public float getVolume()
      Returns the volume of the box.

    • outside

      public int outside(SbMatrix MVP)
      Returns true if bounding box is completely outside the view-volume defined by the model+view+projection matrix given. "cullBits" keeps track of which view-volume clipping planes the box is completely inside of; if a 'parent' bounding box of this bounding box was found to be completely inside the left/right clipping planes, the low bit of cullBits will be set to zero, and this routine will not test this box against those planes. When cullBits is zero, it is a waste of time to call this function! Before calling this the first time, set cullBits to 7 (SoGLRenderAction and SoSeparator will handle this automatically for render culling).

    • extendBy

      public void extendBy(SbVec3f pt)
      Extends this box (if necessary) to contain the specified point.

    • extendBy

      public void extendBy(SbBox3i32 bb)
      Extends this box (if necessary) to contain the specified box.

    • setBounds

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

    • setBounds

      public void setBounds(SbVec3i32 _min, SbVec3i32 _max)
      Sets the corners of the box.

    • getCenter

      public SbVec3f getCenter()
      Returns the center of the box.

    • intersection

      public SbBox3i32 intersection(SbBox3i32 box)
      Returns the intersection of the specified box with this box. Returned box is empty if there is no intersection.

    • intersect

      public boolean intersect(SbVec3i32 pt)
      Returns true if the specified point intersects this box.

    • intersect

      public boolean intersect(SbBox3i32 bb)
      Returns true if the specified box intersects this box.

    • intersect

      public boolean intersect(SbVec3f pt)
      Returns true if the specified point intersects this box.

    • contains

      public boolean contains(SbBox3i32 bb)
      Returns true if the specified box is fully contained inside this box.

    • getMax

      public SbVec3i32 getMax()
      Returns the maximum point of the box. The maximum point is the corner of the box with the highest X, Y, and Z values.

    • getSize

      public SbVec3i32 getSize()
      Gets box size.

    • makeEmpty

      public void makeEmpty()
      Makes an empty 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.)

    • getMin

      public SbVec3i32 getMin()
      Returns the minimum point of the box. The minimum point is the corner of the box with the lowest X, Y, and Z values.

    • getBounds

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

    • getMinMax

      public SbVec3i32[] getMinMax()
      Gets the corners of the box.

    • getOrigin

      public int[] getOrigin()
      Gets box origin which is the same as the minimum corner of the box.

    • getClosestPoint

      public SbVec3f getClosestPoint(SbVec3f 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.)
