[vtkusers] Render Speed (I know.. asked by many already..!)

[Ted Vu]

Hello
so my pipeline is just
ImageData->ImageMapToColors->ImageActor

And using render->GetLastRenderTimeInSeconds it takes about 0.1 s  to render

However, I am building a real-time application (VTK+C++) and I need this to 
be much faster, (maybe 5 times)
Is there anything I can do to help this??

How about using vtkWin32OpenGLRenderWindow?? Does this make things render 
faster by basing the rendering on OpenGL?

My graphics card is already pretty good,  I belive its a 128MB Nvidia 
GeForce

I'd really like to stick to VTK for my application becuase its much easier 
than directly using OpenGL.. but maybe I will have to resort to this?? If 
anything can I make my own RenderWIndow class and call my own Render() 
function where i will leave out the unnecessary computationally expensive 
parts that are in it right now (or is this totally ridiculous and not worth 
attempting?)

Need some direction on how to go about this problem withouht having to buy 
new hardware!!
Thanks for you help
