| PackageDescription | a Python 3 frontend to CGAL's 3D mesh generators
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.
