Detailed Description

VSG extension 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)

FILE FORMAT/DEFAULT

    BBox {
    mode DISABLE
    boundingBox 0 0 0 0 0 0
    }

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

◆ 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.

Definition at line 81 of file SoBBox.h.
