Hi,<br>
I have a three-dimensional image with size 256x256x256. After it is<br>
rendered on the screen, I change some data of the image in a small box<br>
with size 50x50x50. I want VTK only to render the modified data, but leave the unmodified data on the screen. I want to know if VTK supports this. Maybe this is not a VTK issue. What I need to do is to disable the erasion of the image buffer.<br>
<br>
Best,<br>
<br>
Yixun<br>
