DESCRIPTION¶

This engine computes the bounding box and center of a scene graph. The scene graph 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 path is NULL, but the node input is not NULL, the bounding box is computed on the graph rooted by the node. By default, the two inputs are NULL. If both the 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.

INPUTS¶

SoSFNode node

Defines the graph for which the bounding box is computed.

SoSFPath path

Alternatively, defines the graph for which the bounding box is computed.

OUTPUTS¶

(SoSFVec3f) min

Minimum point of the computed bounding box.

(SoSFVec3f) max

Maximum point of the computed bounding box.

(SoSFVec3f) boxCenter

Center of the computed bounding box.

(SoSFVec3f) objectCenter

Center of the objects in the graph.
