<div> </div>
<div>Again I have a question. It's a bit complex, and I am not sure, if I can explain it clearly. Well, I'll try :)</div>
<div>I am working with displaying brainactivity on the cortex. The vtkpolydata of the cortex, or the part I am interested in, already is big. In order to color it the way I want I add (around 2000) arrays to the vtkpolydata and pick one at a time for displaying it.</div>
<div>This includes that I save all the arrays in the memory (more than 3GB) and the calculation for that is quite long. Anyway, I thought, I could do the calculation at runtime and display only the data that I need at that moment. Now, here is the question: Is it possible to do something like that with vtk? The mapper would have to do a few lookups and basic computation.</div>
<div> </div>
<div>Thank you!</div>
<div>Best, Susi</div></div></body></html>
