Bbox3Bvr Class

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 might 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.

Bbox3Bvr Methods

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

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

newUninitBvr Makes it possible to refer to a three-dimensional bounding box behavior before that behavior has been defined.

getMax

Bbox3Bvr Class

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

Syntax

public Point3Bvr getMax( );

Return Value

Returns the Point3Bvr object.

getMin

Bbox3Bvr Class

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

Syntax

public Point3Bvr getMin( );

Return Value

Returns the Point3Bvr object.

newUninitBvr

Bbox3Bvr Class

Makes it possible to refer to a three-dimensional bounding box behavior before that behavior has been defined. With this method, it is possible to 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.

Syntax

public static Bbox3Bvr newUninitBvr( );

Return Value

Returns the Bbox3Bvr object.
