Plotting the volume of a set of 3D data

I have a set of 3d points, implemented as three 5876x1 arrays, called xx yy and zz. These points fill up a region with volume in 3d space and I want to plot the volume that smoothly encapsulates them.

I want to plot the smooth object that these points represent.

In the absence of the data (that I was hoping might magickally appear by now), I suggest using either boundary or alphashape.

If alphashape works (creating closely-fitting boundaries), then use volume to calculate its volume.

I have little experience with these functions (since I rarely need to use them), so it would likely be best for you to experiment with them.
