BoundingBoxListener

MacroModule

genre	InventorMain
authors	Christian Schumann, Christian Rieder
package	FMEstable/ReleaseMeVis
definition	BoundingBoxListener.def
see also	SoComputeBoundingBox
keywords	Bounding, box, inventor, listener

Purpose

Notifies changes of the scene bounding box. Optionally an object selection is used. Can be used to trigger viewAll() on a SoExaminerViewer on scene change for example

Usage

Connect scene below.

Windows

Default Panel

Input Fields

scene

name: scene, type: SoNode

Input inventor scene.

Allow2DBounding Box: Bool	On: Bool
Bounding Box Changed: Trigger	Size: Vector3
Center: Vector3	Valid: Bool
Epsilon: Float
Listen To Object Center: Bool
Max: Vector3
Min: Vector3
Object Center: Vector3

Visible Fields

On

name: on, type: Bool, default: TRUE

Turns module on/off

Epsilon

name: epsilon, type: Float, default: 9.9999997e-05

Used to compute bounding box validity. max must at least be min + epsilon.

Allow2DBounding Box

name: allow2DBoundingBox, type: Bool, default: FALSE

If true, it is sufficient if the bounding box has a size larger 0 in one dimension. If false, a size larger 0 is required in all dimensions for validity.

Min

name: min, type: Vector3, persistent: no

Output of minimal bounding box coordinates

Max

name: max, type: Vector3, persistent: no

Output of maximal bounding box coordinates

Center

name: center, type: Vector3, persistent: no

Output of bounding box center

Object Center

name: objectCenter, type: Vector3, persistent: no

Output of object center

Size

name: size, type: Vector3, persistent: no

Output of bounding box size

Valid

name: valid, type: Bool, persistent: no

Is true if max is larger then man by at least epsilon.

Bounding Box Changed

name: boundingBoxChanged, type: Trigger

Triggered on any change of the bounding box

Listen To Object Center

name: inListenToObjectCenter, type: Bool, default: FALSE

If active, the modules listens to changes of the object center that do not modify the bounding box as well.
