Bbox3Bvr Class

public class Bbox3Bvr extends Behavior {
    // Methods
    public Point3Bvr getMax();
    public Point3Bvr getMin();
        
    public static Bbox3Bvr newUninitBvr();
    
}

Creates an object that represents a three-dimensional bounding box behavior. The behavior specifies the back-lower-left and forward-upper-right corners of a cube that encloses the non-transparent portions of a geometry behavior. Although a bounding box may not always be the smallest bounding box achievable for the geometry, it is useful for determining the extent or size of the visible portions of the geometry.

Applications never create bounding box behaviors explicitly. Instead, these behaviors are created by calling the boundingBox method in the GeometryBvr class.

For more information about behaviors, see the Behavior class.

Methods

getMax

public Point3Bvr getMax();

Creates a three-dimensional point behavior that specifies the forward-upper-right corner of the bounding box.

Return Value:

Returns the Point3Bvr object.

See Also: getMin

getMin

public Point3Bvr getMin();

Creates a three-dimensional point behavior that specifies the back-lower-left corner of the bounding box.

Return Value:

Returns the Point3Bvr object.

See Also: getMax

newUninitBvr();

public static Bbox3Bvr newUninitBvr();

This method allows you to refer to a three-dimensional bounding box behavior before that behavior has been defined. With this method you can create the behavior and use it in the definition of other behaviors, but not actually define its contents until some later point. (This is accomplished with the init method, which is available on all behaviors.) The system generates a run-time error if you initialize a non-uninitialized behavior, initialize an uninitialized behavior that has already been initialized, or run an initialized behavior that has not yet been initialized.

Return Value:

Returns the Bbox3Bvr object.
