Introduction
In this tutorial we learn how to install python3-pygalmesh on Ubuntu.
What is python3-pygalmesh
python3-pygalmesh is:
pygalmesh makes it easy to create high-quality 3D volume and surface meshes.
CGAL offers two different approaches for mesh generation:
- Meshes defined implicitly by level sets of functions.
- Meshes defined by a set of bounding planes.
pygalmesh provides a front-end to the first approach, which has the following advantages and disadvantages:
- All boundary points are guaranteed to be in the level set within any specified residual. This results in smooth curved surfaces.
- Sharp intersections of subdomains (e.g., in unions or differences of sets) need to be specified manually (via feature edges, see below), which can be tedious.
On the other hand, the bounding-plane approach (realized by mshr), has the following properties:
- Smooth, curved domains are approximated by a set of bounding planes, resulting in more of less visible edges.
- Intersections of domains can be computed automatically, so domain unions etc. have sharp edges where they belong.
pygalmesh and mshr are therefore complementary.
pygalmesh also interfaces CGAL’s 3D periodic mesh generation.
This package installs the pygalmesh module for Python 3.
It also provides the utility scripts pygalmesh-from-inr and pygalmesh-volume-from-surface for generating volume meshes from INR or surface meshes.
There are three methods to install python3-pygalmesh on Ubuntu. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install python3-pygalmesh Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get update
After updating apt database, We can install python3-pygalmesh using apt-get by running the following command:
sudo apt-get -y install python3-pygalmesh
Install python3-pygalmesh Using apt
Update apt database with apt using the following command.
sudo apt update
After updating apt database, We can install python3-pygalmesh using apt by running the following command:
sudo apt -y install python3-pygalmesh
Install python3-pygalmesh Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Ubuntu. Update apt database with aptitude using the following command.
sudo aptitude update
After updating apt database, We can install python3-pygalmesh using aptitude by running the following command:
sudo aptitude -y install python3-pygalmesh
How To Uninstall python3-pygalmesh on Ubuntu
