A couple of Seg3D usage questions. To answer the first, you can change the background color in Preferences under the View tab.

Hi Ayla,

I was wondering if you could send this out to the list.

HI All,

I have 2 issues, one of which is likely a 'newbie' one:

Problem 1) Removing black background from volume viewer/seeing true 3D data in volume viewer. 

In the attached image 1a you can see the volume view of my data (it is a layered rock) but it is sill showing the black background and the 3-axis. I would like to remove that black background, see this in 3D with the coloring (of the rock layers visible), not just a single color mask.

Problem 2) Poisson Noise removal

Is there a way to lessen this type of noise in Seg3D? you can see in image 2a a look at the axial plane and the cross-hatched artifacts. I know that I won't be able to remove these entirely, but if I could lessen them I could get to some nice data on the interior of the rock.

Please let me know if you have any tips!
