pip install scikit-gmshimport skgmsh as sgWe can define the surface using PyVista.
source = sg.Polygon(n_sides=4, radius=8, fill=False)We can then generate a 2D mesh.
mesh = source.frontal_delaunay_2d(edge_source=source, target_sizes=2.0)To visualize the model, we can use PyVista.
plotter = sg.Plotter()
_ = plotter.add_mesh(
mesh,
show_edges=True,
line_width=1,
color="aliceblue",
lighting=False,
edge_color="gray",
)
_ = plotter.add_mesh(source, show_edges=True, line_width=4, color="gray")
plotter.show(cpos="xy")
We can also generate a 3D mesh.
source = sg.Cube()
mesh = source.delaunay_3d(edge_source=source, target_sizes=0.2)plotter = sg.Plotter()
_ = plotter.add_mesh(
mesh,
show_edges=True,
line_width=1,
color="aliceblue",
lighting=False,
edge_color="gray",
)
_ = plotter.add_mesh(edge_source.extract_all_edges(), line_width=4, color="gray")
_ = plotter.add_box_axes()
plotter.show()
We can clip a mesh by a plane by specifying the origin and normal. See clip_with_surface_example for more examples using this filter.
clipped = mesh.clip(origin=(0.0, 0.0, 0.0), normal=(0.0, 0.0, 1.0), crinkle=True)
