reason you are not seeing the volume when you move it is because you are
using vtkLODProp3d. LOD stands for Level Of Detail.
Basically, based on how fast your computer can render, vtkLODProp3D would
choose the right object representation to draw. If your computer is not
fast enough to do a volume rendering, then it choose the next level of detail,
which in your case is the outline. When you render a single image, it was
probably fast enough to redraw the image each time. When you have several
images loaded, then your computer may not be able to keep up, therefore the
outline is rendered instead. When you stop the mouse interaction,
then vtk will render the entire volume, which will take some time. You
should not be able to see both at the same time.</FONT></SPAN></DIV>

VolumeRendering problem<BR><BR></FONT></DIV>
<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am using vtk3.2 and java. </FONT></DIV>
<DIV><FONT face=Arial size=2>When I display one image, I can rotate it without
any problems. But when I load several images to output a volume, as soon as I
mouse over, the whole lot disappears.</FONT></DIV>
<DIV><FONT face=Arial size=2>Can anyone explain why this might be
please.</FONT></DIV>
<DIV><FONT face=Arial size=2>I have attached my code.</FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2></FONT> </DIV>
