Summary

This customizer friendly thing enables you to create a rock like thing... There's no science here, a little fun and just some simple OpenSCAD.

Thanks!

How I Designed This

How to make a rock.

            <div><p>The first thing to do in generating a rock is to start somewhere. I decided to start with a sphere. For a while I was trying to understand how to manipulate a primitive sphere, but then I came across this <a rel="nofollow" href="http://makerblock.com/2014/03/openscad-intermediates-how-to-make-complex-organic-shapes/">blog post about creating organic shapes</a>. </p><p>I was resolved to try to create a simple sphere with <code>hull</code>. Which proved a bit difficult, but I decided to brute force it, so if my math's a bit contrived, that is why. But eventually I got there! You can see this sphere in customizer by setting the <code>deformation</code> and <code>skew</code> to 0.</p><p>It's a lot like a sphere, but has extra poly's connecting the vertices, which is fine. According to the blog, using sphere's is wize, but I didnt see much difference between cubes and spheres. Either way, the <code>hull</code> creates a poly around the points!</p><p>With that, I just had to add some randomization to make the object less uniform, and I had my rock.</p><p>Really great story. I know.</p></div>
