<DIV>Hi, there.</DIV>
<DIV> </DIV>
<DIV>Is there any way to retrieve actor by ID or properties? My renderer has various kind of actors and I need to delete and add them dynamically. It's very difficult to track the position of actors using Initialtraversal().</DIV>
<DIV> </DIV>
<DIV>There is no return values for addActor(). Could vtk make some changes so that the addActor() can return a ID for each actor therefore easier to retrieve actors?</DIV>
<DIV> </DIV>
<DIV>Or there is any other way to retrieve actors?</DIV>
<DIV> </DIV>
<DIV>Thanks!</DIV>
