[vtkusers] Speed

[amit saxena]

Hi,
   I am generating a volume  from a data set. I take out the scalar
values of the volume and do the further processing. The problem is vtk
is taking too much time to do thestuff. My pipeline is as follows :
 
vtkVolume16Reader---->vtkReslice--->vtkScalars.  
The update method specially takes lot of time. Is there a way to speed
up the things. Further, I have to handle a very large data set :
2*512*512*100. How to overcome memory problems with such large data
sets?
