SoVRMLBillboarduseSphereBBox Property |
Specifies if the bounding box returned by SoVRMLBillBoard.getBoundingBox() method should be extended to completely contain the bounding sphere of the children.
Namespace: OIV.Inventor.VRMLnodes
This hint avoids bounding box cache breaks due to rotation of the billboard geometry (which changes the default axis aligned bounding box) and provides a significant performance increase when many SoVRMLBillboard nodes are used.
LIMITATIONS: This field is not part of the X3D / VRML standard. When writing the scene graph to an X3D / VRML format file, be aware that the presence of this field will make the file invalid. By default, that is if the value of the field is not modified, the field will not be written.
Default is false
