Computes the bounding box and center of a scene graph.
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.

SoComputeBoundingBox::SoComputeBoundingBox | ( | ) |
Constructor.
static SoType SoComputeBoundingBox::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoEngine.
virtual SoType SoComputeBoundingBox::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Implements SoTypedObject.
const SbViewportRegion& SoComputeBoundingBox::getViewportRegion | ( | ) | const |
Returns the viewport region to use for the bounding box computation.
void SoComputeBoundingBox::setViewportRegion | ( | const SbViewportRegion & | vpReg | ) |
Sets the viewport region to use for the bounding box computation.
( SoSFVec3f ) Center of the computed bounding box.
( SoSFVec3f ) Maximum point of the computed bounding box.
( SoSFVec3f ) Minimum point of the computed bounding box.
Defines the graph for which the bounding box is computed.
( SoSFVec3f ) Center of the objects in the graph.
Alternatively, defines the graph for which the bounding box is computed.
