3D Plot shrinks one dimension when plotting Alphashape

Hello All,

In lines 76-81 of this code I am trying to plot alphashapes on a previously defined figure (line 18). However, whenever I plot, the 3rd dimension seems to shrink down the scales change. I want the 3D plot to look like it does before the plot commands starting in line 76 (you can put a pause anywhere between 18 and 76 to see what I mean). Any help would be great. Thanks

The plot method for alphaShapes sets the data aspect ratio to [1 1 1].

When your code arrives at line 76, the data aspect ratio is [31.25 1 87.5]. (A convenient way to get or set the data aspect ratio is the function daspect. The plot call on line 76 resets it to [1 1 1].

You can call daspect yourself to set the data aspect ratio as desired. For example, at the end of your code, add this line:

daspect([31.25 1 87.5])
