Hello,
In my programme, I have among others a view node and a thread. The
geometries under the view node changes every frame. The thread controls
the frequency at which an IntersectionVisitor visits the view node.
However it turns out it doesn't work. When the intersectionVisitor is
ready to visit the view node, it stops there, without going further.
If the visit of intersectionVisitor is made to be a part of the
updatecallback of view node, then it works.
I wonder if the intersectionVisitor can work separately from the
updatecallback of the node that it visits
Thank you very much in advance for any advice!
Shuiying
