The dodecahedron is a particularly interesting polyhedron. It's full of interesting five-fold symmetries. Let's take a look at a couple of them.First we'll need the vertices. There's an interesting... read more >>

Another new feature that I really like in R2016a is the upgraded fplot function and all of the new members of the fplot family.The fplot function has been around for a long time. The basic idea is... read more >>

Recently I heard from a MATLAB user who was trying to draw tubes along a curve using this blog post I wrote a while back. Unfortunately her curve was a bit more complex than the ones I used in that... read more >>

One type of question that I'm often asked is about how to use various visualization techniques with what is sometimes called "scatter data". This is data that is a list of individual measurements.... read more >>

Last time, when I was talking about permutohedra, we saw how truncated octahedra fill 3D space with no gaps. There are a number of shapes with this property, and they have the lovely old family name... read more >>

In earlier posts we've looked at tiling quadrilaterals and pentagons. So what about hexagons? I'm sure you've seen tilings of regular hexagons. They're popular in floor tiles and game tiles. Even... read more >>

In a recent post, I talked about an interesting edge case in the contour function. Today I'd like to talk about another one. This is how contour handles infinities.Let's start with a simple example.... read more >>

In an earlier post, we discussed how the contour functions interpolate between values. Another important issue is how the contour functions deal with contour levels which are exactly the same as values in the input data. Some users are often surprised by what happens in this case because there are some subtle issues involved. Let's take a detailed look.... read more >>

What is a Contour?Last year we explored how surfaces perform interpolation. Today we're going to take a look at some closely related functions; the contour family. The family of contour functions... read more >>

Tiling QuadrilateralsLast time I was talking about the new pentagon tiling which was recently discovered. There are lots of other wonderful things to explore in how polygons tile the plane. One of my... read more >>
