    Making a Sweeping Slice Through Volume of Data

    (Originally posted on Doug's MATLAB Video Tutorials blog.)

    A MATLAB user recently asked how we could make a visualization similar to this one.

    I was a little surprised that we were able to do the visualization, with interactivity in less that 15 lines of code.

    d = flow; d = shiftdim(d,2);
    x = 25;
    y = 26;
    z = 21.59561;
    v =  3.22068;
    
    h = slice(d,x,y,z)
    d(:,:,z:end) = nan;
    isosurface(d,-v)
    
    set(h,'edgeColor','none')
    axis equal
    zlim([0 size(d,3)])
    colormap spring
    


    This video makes use of cell mode to get the interactivity. You can see how something like this could be done with a GUI to get the interactivity that you might want.

    If you like this kind of thing, Slice-o-matic, will be good for you.
