Let's meditate a bit on the following functions:

1. f(x,y) = sqrt(x*y)
2. f(x,y) = 2/(1/x + 1/y)

They are the geometric and the harmonic mean, both of which take a list of numbers, in this case two, and return a "summary" of …

As methods for estimating 6D poses from images gather momentum, "Normalized Object Coordinates" have entered the arena. These are pixel-wise encodings of the object position. In that sense, they are like a normal map, but instead of encoding the normal at every point, they encode the position.

How can we …

If you're new in an engineering field, or if you're paying attention in school, you will have heard of models. I used to be confused when people described the equation of a falling body as a "physical model". Since, after all it's just a description of reality, right? What does …

Getting a depth map out of blender is a little akward, but possible. The method that is usually recommended isn't entirely correct though. So let's take a look at it and find out what's wrong.

The Usual Method

You can get the depth from Blender via the Compositor, for artistic …

Suppose you have a mesh with ugly triangles and you want to make it nicer. Have these beautiful equilateral triangles. Or, you want to deform a mesh by dragging on some control points. Or, maybe you want to compress your meshdata on a server, and only send parts of it …

If you also fell under the spell of the beauty that is Viridis and have been lacking its presence in Meshlab, here you go. A .qmap version of the colormap, to be used with Meshlabs Quality Mapper.

Download qmap or the python script that generated it (How to use).

Last time, I described the first "evolutionairy algorithm" I made. This time, let's have a look at a newer one I wrote:

It tries to build some sort of bridge to the right. On the left hand side, you can see the best individual of each generation. On the right …

In an effort to become more organized, I want to share the stuff I program in my freetime. Because you know, somehow it helps, if you write about your projects. Makes you think them over once more.

So quite a while back, I stumbled upon evolutionary algorithms. They mimic some …
