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

Answer 1

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
