<DIV><FONT face=Arial size=2>two questions about 3D images :</FONT></DIV>
<DIV><FONT face=Arial size=2>1/ Is it possible to show only a part of an image
and when I move to change this part ? For example to show only what the camera
really see. Because I think that vtk recalculate all the points and not only the
points that are visibles.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2/ I have a 3D image with 1000 points but when I
zoom in i want to change the number of points to 10 000 is it
possible?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I want to do this because the speed decrease very
quickly whan I zoom and to have a better resolution of my image when I am
closer.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>thank you for your anser and sorry for my
english</FONT></DIV>
