[vtkusers] How to improve the volume rendering's speed?

[Cameron Burnett]

I'm doing the same thing with my project at the moment. I've read that its a very slow algorithm, yet its highly accurate... so i'm not so sure if there is a lot that can be done. However I thought that maybe you could wrap the outside of the object with a low poly mesh or something, but I haven't really given it much thought. The problem I had was that I was reading in DICOM data, and I'm fairly sure there isn't many more methods other than the ray cast one that I could use for that format. I'm a noob though, so I could be very wrong :P.

Hi, vtk users,

    now I am doing volume rendering with ray casting method. but I find it is very slow especially when the image number is more than one hundred, and I want to improve the volume rendering's speed, is there any good idea to do it? any idea would be appreciated~

    and thank you very much!
