Example meshes

mesh = example(which::Symbol[; shift=nothing, scale=nothing,
                               z=nothing, transform=nothing, args=())

Generate example mesh, possibly with transformed geometry.

• shift apply translation
• scale apply uniform scaling
• z set z-coordinates to z(x, y) (e.g., to lift planar meshes)
• transform apply linear transformation. Note that transform and the above options are exclusive!
• args provide additional arguments to generators (e.g., example(:ring, args=6)).

Available meshes include

which ∈ [:empty, :single_point, :unit_triangle, :unit_quad,
:two_triangles, :isolated_vertex, :eight, :unit_tetrahedron,
:unit_cube, :tetrahedron, :octahedron, :ring, :valence3,
:gargoyle, :gargoyle_cut, :beetle, :small_gargoyle, :small_bunny,
:planar1, :planar2, :planar3, :bunny, :fandisk, :hemisphere,
:sphere, :small_sphere, :isosahedron, :amo]

path = examplefile(filename[; ext="off", url=nothing, dl=dlinfo])

Get path example filename using file extension ext and url for download if the file is not already available in the local data directory dest.

If the local destination directory dest does not exist, it will be created. The url defines the base resource path, the filename will be appended for download.

The callback dl will be called directly before download. The default callback will output via @info.

x, t = generate_ring(n)
