Ulam spiral: Number theory matters -oh no, forms matter, summing it up NUMBER THEORY FORMS MATTER

Hi,

this is one of my simplified models. It shows  the natural numbers  from 1 to 36 as cubes in an Ulam spiral.

You can read about Ulam spiral here: Ulam spiral

Here you see the node graph and the OpenSCAD rendering:



You see me trying to set the viewport variables $vpr, $vpt and $vpd, which did not function.
The primefield was computed for numbers 1 to 1,000,000 by a Python script, the first 36 lines were copy-pasted into the node string node.

And finally the gscad file - zipped.

very interesting.

In fact i checked openscad behaviour for $vpt etc...
These vars are used as global and seem having no effect when used in module parameter.
I will a a global node 'openscadsettings ' for all these vars, so that you'll be able to set then before declaration of module

here is your file working with version V1.0.6 (new nodes of globalsettings, and switchcase). Have fun.
