Hi j3d experts,
I have an issue with cleaning up of the scene graph. We have a
SDI( Single document Interface) CAD viewer where while opening a cad model we
clean up( basically detach the root BG from the Locale and set all the nodes to
null to clear the memory) the scene graph of the previous model. This takes lot
of time. So what happens is while opening even a small model it takes lot of
time if the previous model was big( lakhs of geometry nodes). Profiler shows a
cleaning up time as more as 70( this factor completely depends on the sizes of
the previous & current model ) times than actual loading time.
How can we optimize it? Should we do the clean up the previous
scene graph nodes in a parallel thread without showing the previous model in the
scene?
hope to get some clue from you !
thanks
anirban
