Fast operators for triangular meshes.
tmesh is available on PyPI:
pip install tmeshSee the examples directory to see how to use the package.
The following script demonstrates how to use the package to generate an STL or OBJ file from a simple mesh:
import math
from tmesh import regular_polygon_mesh, Affine2D, linear_extrude
# Create a cuboid.
a = regular_polygon_mesh(1.0, n=4)
b = regular_polygon_mesh(1.0, n=4)
# Move the second cuboid around.
rot = Affine2D(rot=math.pi / 4)
trans = Affine2D(trans=(0.0, 0.5))
b <<= rot @ trans
# Gets the union of A and B.
c = a | b
# Extrudes the 2D mesh to a 3D mesh with height 1.0.
mesh = linear_extrude(c, 1.0)
# Save the resulting mesh.
from tmesh import save_stl, save_stl_text, save_obj, save_ply
save_stl_text("simple_example_ascii.stl", mesh)
save_stl("simple_example.stl", mesh)
save_obj("simple_example.obj", mesh)
save_ply("simple_example.ply", mesh)At various times I have wished there were something like OpenSCAD for Python. Packages like trimesh exist, but they come with a number of clunky dependencies (including, interestingly enough, OpenSCAD itself). This package is a standalone implementation of the core functionality of OpenSCAD, but with a Pythonic API, making it easy to integrate into existing Python code. It is also written in pure C++, so it's hopefully relatively fast.
