SoBillboarduseSphereBBox Property |
Specifies if the bounding box returned by SoBillboard.getBoundingBox() method should be extended to completely contain the bounding sphere of the children.
Namespace: OIV.Inventor.Nodes
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 SoBillboard nodes are used.
Default is true
