GitHub - fogleman/sdf: Simple SDF mesh generation in Python

sdf library
in a Python virtualenv.
git clone https://github.com/fogleman/sdf.git
cd sdf
virtualenv env
. env/bin/activate
pip install -e .
Confirm that it works:
You can skip the installation if you always run scripts that import
sdf
from the root folder.
File Formats
sdf natively writes binary STL files. For other formats, meshio
is used (based on your output file extension). This adds support for over 20 different 3D file formats,
including OBJ, PLY, VTK, and many more.
Viewing the Mesh
Find and install a 3D mesh viewer for your platform, such as MeshLab.
I have developed and use my own cross-platform mesh viewer called meshview (see screenshot). ....

Metaballs and Marching Squares

Metaballs and Marching Squares
Click any of the animations to pause
Something about making visually interesting simulations to play with just gets
me really excited about programming, particularly when there’s some cool
algorithm or bit of math backing it.
Reading a bit about particle simulations on Wikipedia, I stumbled upon
metaballs. In 3D, metaballs looks something like this:
From Metaballs
on Wikipedia
This looked like it had the potential to yield some cool behaviour, so I decided
to dive in. To start, I just wanted some circles bouncing around, like this:
Sweet. The next step is to make these things blobby. ....

Smooth Voxel Terrain (Part 2)

For the sake of concreteness, let us suppose that we have approximated our potential field
by sampling it onto a cubical grid at some fixed resolution. To get intermediate values, we’ll just interpolate between grid points using the standard trilinear interpolation. This is like a
generalization of Minecraft-style voxel surfaces. Our goal in this article is to figure out how to extract a mesh of the implicit surface (or zero-crossings of
). In particular, we’re going to look at three different approaches to this problem:
Marching Cubes
By far the most famous method for extracting isosurfaces is the marching cubes algorithm. In fact, it is so popular that the term `marching cubes’ is even more popular than the term `isosurface’ (at least according to Google)! It’s quite a feat when an algorithm becomes more popular than the problem which it solves! The history behind this method is very interesting. It was originally published ba ....
