Purpose

The engine SoComputeBoundingBox computes the bounding box and center of a scene graph, which can be defined by a path or by a root node.

If the Path input is not NULL, the bounding box of the graph defined by the path will be computed. If the path is NULL but the node input is not NULL, the bounding box is computed for the graph rooted by the node. By default, both inputs are NULL. If both inputs are NULL, the outputs are disabled.

The engine uses a default viewport region. If the graph includes screen-based objects (such as SoText2), you can call setViewportRegion() on the engine instance to set up the correct viewport region to use.

Visible Fields

Path

name: path, type: SoPath

Optionally sets the path of the graph for which the bounding box is computed.

Min

name: min, type: EngineOutput, persistent: no

Outputs the minimum point of the computed bounding box.

This field must be connected to an appropriate Open Inventor field to access or view its value.

Max

name: max, type: EngineOutput, persistent: no

Outputs the maximum point of the computed bounding box.

This field must be connected to an appropriate Open Inventor field to access or view its value.

Box Center

name: boxCenter, type: EngineOutput, persistent: no

Outputs the center of the computed bounding box.

This field must be connected to an appropriate Open Inventor field to access or view its value.

Object Center

name: objectCenter, type: EngineOutput, persistent: no

Outputs the center of the objects in the graph.

This field must be connected to an appropriate Open Inventor field to access or view its value.
