MATLAB: How to change the color of an alphaShape object when using plot

Question

I have a 3-D object which I've converted to a very nice looking alphaShape object after getting the PixelIdxList and using ind2sub to get the coordinate of each voxel.

As awesome as they look, I really really need to change the color of some of the objects to anything other than the default green. Any idea on how to change the color?

Answer 1

You can grab the handle to the patch objects making up the alpha shape as the output from plot and then change whatever properties of it you want:

data = randn(100,3);
as = alphaShape(data);
h = plot(as);
h.FaceColor = 'b';
