[vtkusers] 回复： how to update a renderwindow everytime when I changethe actor's data by some keypress operations?

[老猫]

Thank you.I thought the problem is comlicated.So I thought it might need filter.I have solved this problem yesterday.I was stupid at that time!
 But there is another problem. I can't find a transform function of an actor.I can rotate it, but I want to transform it by pressing the keybord.Could you please give me some ideas? Thank you very much.

I think you just need to call renderWindow->Render() ?
