[vtkusers] multiple Maximum Intensity Projection (volume rendering)

[Stéphane CALANDE]

Hi vtkusers,


I've attached a program that I created to display MIP's of a volume (from a
dicom serie).

As you can see, a MIP is generated each 6° degree around the volume.
Then, there are 60 MIP's in total (360/6)
Each view is saved as a png file.


But I've some questions...

1) I find that the rendering is not so beautiful. The picture is a little
vagueness. Can I do something to improve that?
2) It takes a lot of time to display one MIP (about 2.83 second per MIP on
my computer (WinXPx64))
3) The distance between the focal point and the camera position is
determined by the variable "distanceFocale". But I've some trouble with the
value of that variable. I don't know which value I have to assign to it,
because : if I assign it a too high or too low value, there is no result
(black window). The rest of the time, the maximum intensity projection
doesn't take into account all the volume but only a part of it (it seems
that the distance is too small).


Thanks a lot,


Best regards,


Stéphane


PS: thanks for your help, Kevin.
