Volume rendering does not appear in 3D view

I can’t seem to get Volume Rendering to work with a Sequence Browser pointing to a volume sequence. Here is a screenshot:

It is most likely not related to sequences. A few things to check:

  • Try to switch to CPU volume rendering. GPU volume rendering does not work on all configurations.
  • Click the small box icon (to the right from the pushpin icon) at the top of the 3D view to make sure the volume is in the field of view.

I pressed them in each view and changed to CPU volume rendering but nothing happens…

You are right that it is probably not related to sequences. I did the following steps:

  1. saved that one volume frame as a nrrd
  2. closed the scene
  3. opened the saved frame

and it did the same thing and nothing showed up.

However, if I do these steps with this volume it works just fine

This is the sequence I am using:

I’ve tried to visualize this data set and I can confirm that your problem was that the volume was not in 3D view’s field of view by default. The solution was to click the reset FOV button.

Thank you, it works now

I cant’t get anything shown in 3D view at all - are there any additional steps than the ones described above?

I tried the dataset mentioned above (http://slicer.kitware.com/midas3/download/item/299877/CTP-cardio.seq.nrrd)
and clicked the reset FOV button several times… but still:

found it in another tutorial:

I did not click on the “eye” Symbol next to “Volume”. Now it works :slight_smile:
