volume plotting examples¶

Example 1: Create Steno3D Project with a Volume resource from 3D matrix

V = flow;
example1 = steno3d.volume(V);
clear V;

Example 2: Create Project with Volume resource offset from origin

example2 = steno3d.volume([-12.5 5 -12.5], flow);

Example 3: Create Project with irregularly spaced Volume resource

xedge = [-20:2:-10 -9:9 10:2:20]; yedge = xedge; zedge = -10:10;
xcent = (xedge(1:end-1) + xedge(2:end))/2;
ycent = (yedge(1:end-1) + yedge(2:end))/2;
zcent = (zedge(1:end-1) + zedge(2:end))/2;
[X, Y, Z] = ndgrid(xcent, ycent, zcent);
dist = sqrt(X.*X + Y.*Y + Z.*Z*4);
example3 = steno3d.volume(xcent, ycent, zcent, dist);
clear xedge yedge zedge xcent ycent zcent X Y Z dist;

Example 4: Create Project with two Volumes

[xvals, yvals, zvals] = ndgrid(-8:4:8, -9:2:9, -9.5:9.5);
example4 = steno3d.volume(                                   ...
    4*ones(5, 1), 2*ones(10, 1), ones(20, 1), [-10 -10 -10], ...
    'X-Values', xvals, 'Y-Values', yvals, 'Z-Values', zvals  ...
);
[~, vol] = steno3d.volume(                                   ...
    example4, ones(20, 1), ones(20, 1), 2*ones(10, 1),       ...
    [-10 -10 15], 'Random Data', rand(20, 20, 10)            ...
);
vol.Opts.Opacity = 0.75;
vol.Mesh.Opts.Wireframe = true;
example4.plot();
clear xvals yvals zvals vol;

You can run the above examples with:

steno3d.examples.volume

Then plot the projects with:

example1.plot(); % etc...
