Posts about Geometry

People have been making Geomag models for a long time (at the very least 15 years maybe 20). I dedicate this page to the Geomag community where I have gathered hundreds of the fantastic creations they have built and that I could replicate after roaming through the internet.

A lot of great people have been sharing polyhedra stuff on the internet. This is a tribute to them where I have gathered websites, pages, illustrations, pieces of software, toys that I came upon over the years. If you think yours is missing, write to me please.

The goal is to gather near miss solids found by people across the internet and display them here, in this amazing interactive gallery !

Voxel models are nice so I made an interactive viewer to help people reproduce some of my original cube-based modular origami models.

What kind of structures would you be able to build if you had a few hundred or thousand dodecahedra or icosahedra at hand ? A surprising answer is Golden Rhombic Solids among other things like tree and flower like structures.

Once again, I am making a viewer, this time the challenge is about handling very large datasets of polycubes. Everything started from a YouTube video, what a surprise !

I've already tackled the problem in 2D. Here is the rest of the story in one more dimension. It is unexpectedly simple ! Yeah !

I have added a new feature to the viewer, namely a way to search for a specific polyhedron according to its number of vertices, faces and other filters. There is also new Geomag and Supermag models as well as the corresponding render style.

The golden ratio is a mathematic wonder that when applied to polyhedra outputs a new category surprising by its properties. It led to edge augmented polyhedra and some improvements of the viewers.

In a previous post, I have presented parquet polygons. I have transposed the generation code into JavaScript and made an interactive viewer out of it.

I like playing with magnets but it is limited to simple models with a few hundreds of elements at most. Here I show my results of using Stella software to produce more complex model using repetitive actions.

During my childhood, my parents bought me Legos, K'nex, Megabloks and Meccano sets. Apart from the Lego, the only ones I have kept are my three boxes of Supermag Magnetic Genius.

During my quest towards polyhedron with regular faces, I have discovered the work of a lifetime by Alain Lobel, a French architect. This is will be the first of many post on the subject.

As a complement to the main viewer, here are galleries for the polyhedra organized by family.

The interest arose during some thinking about the arrangement of faces around the vertex of a polyhedron. Here is the solution in 2D.

The idea behind parquet polygons is to extend regular polygons to convex shapes made of them. Here, I will show what they look like and how to generate them. At the end, they will be turned into prisms to be viewed with the polyhedra viewer !

Here is the full screen interactive viewer for polyhedra. I will use it to display all the polyhedra I have found over the internet or made by myself.

Even though I have not explained anything about convex polyhedra with regular faces yet, I have decided to post this network first. It is a tool I have made to better visualize the construction relationship between the many solids.
