public Bounds()
```
    Constructs a new Bounds object.

  - clone
```
public abstract java.lang.Object clone()
```
    Makes a copy of a bounds object.
    
    Overrides:
    
    clone in class java.lang.Object
  - equals
```
public abstract boolean equals(java.lang.Object bounds)
```
    Indicates whether the specified bounds object is equal to this Bounds object. They are equal if both the specified bounds object and this Bounds are instances of the same Bounds subclass and all of the data members of bounds are equal to the corresponding data members in this Bounds.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    bounds - the object with which the comparison is made.
    
    Returns:
    
    true if this Bounds object is equal to bounds; otherwise false
    
    Since:
    
    Java 3D 1.2
  - hashCode
```
public abstract int hashCode()
```
    Returns a hash code for this Bounds object based on the data values in this object. Two different Bounds objects of the same type with identical data values (i.e., Bounds.equals returns true) will return the same hash code. Two Bounds objects with different data members may return the same hash code value, although this is not likely.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    a hash code for this Bounds object.
    
    Since:

  - intersect
```
public abstract boolean intersect(javax.vecmath.Point3d origin,
                                  javax.vecmath.Vector3d direction)
```
    Test for intersection with a ray.
    
    Parameters:
    
    origin - the starting point of the ray
    
    direction - the direction of the ray
    
    Returns:
    
    true or false indicating if an intersection occured
  - intersect
```
public abstract boolean intersect(javax.vecmath.Point3d point)
```
    Test for intersection with a point.
    
    Parameters:

    Returns:
    
    true or false indicating if an intersection occured
  - intersect
```
public abstract boolean intersect(Bounds boundsObject)
```
    Test for intersection with another bounds object.
    
    Parameters:

  - closestIntersection
```
public abstract Bounds closestIntersection(Bounds[] boundsObjects)
```
    Finds closest bounding object that intersects this bounding object.
    
    Parameters:
    
    boundsObjects - an array of bounds objects
    
    Returns:
    
    closest bounding object
  - combine
```
public abstract void combine(Bounds boundsObject)

    Parameters:
    
    boundsObjects - an array of bounds objects
  - combine
```
public abstract void combine(javax.vecmath.Point3d point)

    Combines this bounding object with a point.
    
    Parameters:
    
    point - a 3d point in space
  - combine
```
public abstract void combine(javax.vecmath.Point3d[] points)
```
    Combines this bounding object with an array of points.
    
    Parameters:
    
    points - an array of 3d points in space
  - transform
```
public abstract void transform(Transform3D trans)
```
    Transforms this bounding object by the given matrix.
    
    Parameters:
    
    trans - the transformation matrix

```
public abstract void transform(Bounds bounds,
                               Transform3D trans)
```
    Modifies the bounding object so that it bounds the volume generated by transforming the given bounding object.
    
    Parameters:
    
    bounds - the bounding object to be transformed
    
    trans - the transformation matrix
  - isEmpty
```
public abstract boolean isEmpty()
```
    Tests whether the bounds is empty. A bounds is empty if it is null (either by construction or as the result of a null intersection) or if its volume is negative. A bounds with a volume of zero is not empty.
    
    Returns:
    
    true if the bounds is empty; otherwise, it returns false
  - set
```
public abstract void set(Bounds boundsObject)
```
    Sets the value of this Bounds object.
    
    Parameters:
    
    boundsObject - another bounds object.
