Poor Man's Circle Packing


Recommended Posts


lately I got flooded with links and references about rhino-scripted topologies.


Being a learned product designer Rhino sits here on my shelf and - well it's sitting there.


Why scripting, if I can use the magic of Houdini?


What's missing? At least the cuttings.

Maybe I find a local laser cutter shop or another rapid prototyping facility to make this more contemporary.

I hope you like it regardless being just virtual.

The project generated some spin offs, which I will be posting the next days.

Some Details:

The base idea is to convert each primitive of a geometry into a 'circle'. I'll explain this in detail in an article I will be posting soon.

I didn't use PBR - just two spot lights.

I rendered a shadow pass for the floor and the structure and comp'd it in Houdini.

I spend the last two days trying to animate this quick hack.

My first aproach was to build the items as nurbs, which resulted in tearing seams when being animated.

I tried any way to build a ring like geometry I could imagine but everything failed.

Digitallysane kindly reminded me of the third input of the sweepSOP this morning.

Here are two movies:

The flipping structue:


The non flipping structure:

This is similar to something I did in response to a question before.

This is very smart - where is this question?

But I am glad I didn't read it - I would have missed a lot of fun.

I didn't know one needs two primitive sops to get rid of the sharp corner.

It wasn't here. Nothing much, someone wanted to do "circles" akin to some real life art they had an online pic of.

An idea I had for it was to kinda like inject bubbles into the system via particles or something. But I never got around to it.
