Dear vtk users:

I want to move a small object, say a 3D cone, within a complex but
static 3D image. As it takes much long time to re-render the whole image
and it is not necessary to do so. So my question is :
 Is it possible that to keep the static image on the screen, while
only render the parts that is changed? More specific, here only the cone
is moving with the cursor, only re-render the cone but not the whole
window->Render()? I heard something of  modifying part of the frame
buffer, but not details on this.

Any suggestion are highly appreciated.

With regards

Dingrong Yi
