pytetwild 0.1.dev1

安装

我们为Windows和Linux x64预构建了Python 3.8 - Python 3.12的wheel。

安装pytetwild的推荐方法是使用PyPI

pip install pytetwild

您也可以克隆存储库并从源代码安装它，但由于涉及C++，构建稍微复杂一些。有关更多详细信息，请参阅CONTRIBUTING.md。

使用

要从PyVista四面体化表面网格

import pyvista as pv
import pytetwild

# Load or create a PyVista PolyData surface mesh
# Here, we'll create a simple sphere mesh as an example
surface_mesh = pv.Icosphere(nsub=2)

# Convert the surface mesh to a tetrahedral mesh. For this example let's
# use a coarse mesh
tetrahedral_mesh = pytetwild.tetrahedralize_pv(surface_mesh, edge_length_fac=1))

# Visualize the tetrahedral mesh in an "exploded" view
tetrahedral_mesh.explode(1).plot(show_edges=True)

您还可以处理原始数组。这里是一个简单的立方体，我们将其转换为四面体。

import numpy as np

# Define vertices of the cube
vertices = np.array([
    [0, 0, 0],  # Vertex 0
    [1, 0, 0],  # Vertex 1
    [1, 1, 0],  # Vertex 2
    [0, 1, 0],  # Vertex 3
    [0, 0, 1],  # Vertex 4
    [1, 0, 1],  # Vertex 5
    [1, 1, 1],  # Vertex 6
    [0, 1, 1]   # Vertex 7
])

# Define faces using vertex indices
# Each face is a rectangle (also accepts triangles)
faces = np.array([
    [0, 1, 2, 3],  # Front face
    [1, 5, 6, 2],  # Right face
    [5, 4, 7, 6],  # Back face
    [4, 0, 3, 7],  # Left face
    [4, 5, 1, 0],  # Bottom face
    [3, 2, 6, 7]   # Top face
])
v_out, tetra = pytetwild.tetrahedralize(vertices, faces, optimize=False)

Additional Parameters
---------------------
edge_length_fac : float, default: 0.05
    Tetrahedral edge length as a function of bounding box diagional. The
    default ideal edge length is bb/20 (bounding box divided by 20).
optimize : bool
    Improve the minimum scaled Jacobean for each cell. This leads to higher
    cell quality at the expense of computation time.
