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​(java.lang.Object obj)

        equals in class java.lang.Object
      • toArray

        public static SbBox3d[] toArray​(long nativeArray,

        Transforms box by matrix, enlarging box to contain result.
      • getVolume

        public double getVolume()
        Returns the volume of the box.
      • setBounds

        public void setBounds​(double xmin,
                              double ymin,
                              double zmin,

                              double zmax)
        Sets the corners of the box.
      • extendBy

        public void extendBy​(SbVec3d pt)
        Extends this box (if necessary) to contain the specified point.
      • extendBy

        public void extendBy​(SbBox3d bb)
        Extends this box (if necessary) to contain the specified box.
      • getCenter

        public SbVec3d getCenter()
        Returns the center of the box.
      • setBounds

        public void setBounds​(SbVec3d _min,
                              SbVec3d _max)
        Sets the corners of the box.
      • intersect

        public boolean intersect​(SbVec3d pt)
        Returns true if the specified point intersects this box.
      • contains

        public boolean contains​(SbBox3d bb)
        Returns true if the specified box is fully contained inside this box.
      • intersection

        public SbBox3d intersection​(SbBox3d box)
        Returns the intersection of the specified box with this box. Returned box is empty if there is no intersection.
      • outside

        public int outside​(SbMatrixd 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).
      • intersect

        public boolean intersect​(SbBox3d bb)
        Returns true if the specified box intersects this box.
      • getBounds

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

        public void makeEmpty()
        Makes an empty box.
      • getSize

        public double[] getSize()
        Gets box size.
      • 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.)
      • getOrigin

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

        public SbVec3d[] getMinMax()
        Gets the corners of the box.
      • getMax

        public SbVec3d 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.
      • getClosestPoint

        public SbVec3d getClosestPoint​(SbVec3d 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

        public SbVec3d 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.
