Detailed Description

Bounding box node.

This class specifies a bounding box during scene graph traversal. This allows the application to use an application defined bounding box or to stop a getBoundingBox action for the current scene graph branch. Note: if a projection is defined in the scene graph, the SoBBox is ignored.

This can be useful, for example:

• To specify the bounding box of some very large geometry.
  For example to avoid the CPU time to calculate the bounding box. (Use mode = USER_DEFINED)
• To "hide" some geometry from the bounding box calculation.
  For example to avoid having annotation geometry, like legends and titles, affect the viewer's viewAll operation. (Use mode = NO_BOUNDING_BOX)

ACTION BEHAVIOR

SoGLRenderAction
If enabled, draws the specified bbox when complexity type = BOUNDING_BOX.

SoGetBoundingBoxAction
If enabled, stops traversal of this portion of the scene graph and, if mode = USER_DEFINED, adds the specified bbox to the accumulated bbox.

Member Enumeration Documentation

enum SoBBox::Mode

This enum specifies how the node interacts with OpenInventor during a traversal.

Enumerator:

DISABLE	The node doesn't do anything.
NO_BOUNDING_BOX	SoGetBoundingBoxAction will ignore subsequent nodes in this portion of the scene graph (as if the nodes don't exist).
USER_DEFINED	SoGetBoundingBoxAction will ignore subsequent nodes in this portion of the scene graph and use the box specified in the boundingBox field as the bounding box of those nodes. When the complexity type is BOUNDING_BOX (see SoComplexity), SoGLRenderAction will ignore subsequent nodes in this portion of the scene graph and render the box specified in the boundingBox field.
