public class SoLocalBBoxMatrixElement extends SoElement
Stores the transformation matrix from object space to some local coordinate space during application of anSoGetBoundingBoxAction
. This element stores the transformation matrix from object space to some local coordinate space during application of anSoGetBoundingBoxAction
. This element is needed to allow separators (and other caching nodes) to store cached bounding boxes in their own local space. Shapes that extend the current bounding box computed by the action use this matrix to transform the bounding box into local space. Separators cache this box, then transform it into the next local space up the hierarchy.Because this element is set to identity by separators before traversing their children, it can never have an affect on any caching separator that it is not under. Therefore, it should never be tested for cache invalidation, so its
matches()
method prints an error message and returns false. It also means that it does not have to save node id's so there are no nodes passed in to any of the methods.
