<br><div class="gmail_quote">Hi, I am a newbie in VTK coding. I have VTK 5.10 installed on my PC running windows XP.. I am trying to develop an application where I need to blink or glow or change the color of an actor. I am trying out on one of the demo example cone4 that came with the source code. My apologies if its a stupid question but I was wondering if I can change the properties of actor like color while it is rendered and running the window-interactor. Since from what I have understood, once the interactor runs, the actor can be moved but I cant seem to change its properties since it continues the interactor loop. I have a snippet of the code I am running, may be it might help to understand what I intend to do. The cone moves and changes color at every iteration (2 second per iteration). But if I also simultaneously want to interact which I try to do by uncommenting the highlighted text, it wont serve the purpose. Any thoughts of how I can accomplish this blinking actor. I would really appreciate your help.<br>
