I don't now where this project is heading, so there's no documentation yet.

Installation

python3.10 -m venv venv
source venv/bin/activate
pip install -e .[dev]
sudo apt install cloc  # for source code line counting

If you see the following error when running mayavi2:

********************************************************************************
WARNING: Imported VTK version (9.3) does not match the one used
         to build the TVTK classes (9.2). This may cause problems.
         Please rebuild TVTK.
********************************************************************************

try updating vtk to the correct version:

pip install -U vtk==9.2

Testing

Run unit tests:

make test

Produce a coverage report:

make coverage

TODO:

• Check if all points of a wall are coplanar
• Triangle area: https://en.wikipedia.org/wiki/Heron%27s_formula
• Triangulation:
  • https://www.geometrictools.com/Documentation/TriangulationByEarClipping.pdf
  • https://nils-olovsson.se/articles/ear_clipping_triangulation/
• Accurate center of weight for Wall
• Tests are failing
• Check whether a point lays on the surface of a polygon
• Check whether a point is inside a Solid
• Use mayavi instead of matplotlib: https://docs.enthought.com/mayavi/mayavi/index.html
• Delaunay triangulation of a polygon -> Polygon.delaunay_triangulation()
• Pretty mesh rendering
• Mesh points on the edges should be shared across all connected polygons
• one config
• Mesh face polygons should have the same surface normals as the polygon
• Add to PyPi to reserve the name
• Fix highly skewed triangles in Delaunay triangulation
• Delaunay triangulation of a solid
• Discretize solid with tetrahedra
• Calculate solid volume
• Accurate center of weight for Solid
• Wall could be a collection of Polygons instead of a Polygon subclass
• Zone could be a collection of Solids instead of a Solid subclass
