How to visualize 3D volume?

Question

I had tried the following demo code in Matlab. I'm using Matlab 2018b

load('spiralVol.mat');
h = volshow(spiralVol);

But I'm getting a black screen.imshow() is working properly. Is it related to opengl? i tried opengl software and opengl hardware

Is it a bug in matlab 2018b? or is it related to my system configuration

I'm unable to reproduce this "black screen". I'm getting this figure: https://i.stack.imgur.com/8TAMP.png. Using MATLAB R2018b. — rayryeng, Oct 28 '18 at 08:33
Could it just be a slow machine that is taking forever to render? — Mad Physicist, Oct 29 '18 at 05:44
You should probably contact MATLAB support for things like this (or your campus license administrator if you're using a campus license). — Cris Luengo, Oct 29 '18 at 05:47
Go to mathworks.com, click on "Support" along the top of the page, then "Contact Support", that leads to this page: https://www.mathworks.com/support/contact_us.html — Cris Luengo, Oct 29 '18 at 06:03

The black screen is sometimes an issue due to bad graphics driver. Try updating the driver to its latest version.

Alternately, Image Processing Toolbox has a 'VolumeViewerUseHardware' preference setting which tells it not to use the graphics card while rendering. Try setting it to false and see if it resolves the issue: iptsetpref
