Installation

There are wheels available for Linux and macOS X. All you need to do is:

pip install admesh

If you have a platform not supported by the above, you’ll need to install the C ADMesh library.

This release is designed for ADMesh 0.98.x. Follow the instructions there. Then you can install this as usual with one of the following:

./setup.py install
python3 setup.py install # for Python 3
pip install admesh # install directly from PyPI

In case your ADMesh library is located in non-standard location, you’ll have to tell the compiler and linker where to look:

LDFLAGS='-L/path/to/library' CFLAGS='-I/path/to/header' ./setup.py install

Usage

Use the Stl class provided.

import admesh

# load an STL file
stl = admesh.Stl('file.stl')

# observe the available methods
help(stl)

# read the stats
stl.stats

# see how many facets are there
len(stl)

# walk the facets
for facet in stl:
    # get the normal
    facet['normal']
    # walk the vertices
    for vertex in facet['vertex']:
        # read the coordinates
        vertex['x']
        vertex['y']
        vertex['z']

# add another set of facets
# every facet is a tuple (vertices, normal) or a dict
stl.add_facets([
    (((0, 0, 0), (0, 1, 0), (0, 0, 1)), (1, 0, 0)),
    {'vertex': [{'x': 0, 'y': 0, 'z': 0},
                {'x': 1, 'y': 0, 'z': 0},
                {'x': 0, 'y': 0, 'z': 1}],
     'normal': {'x': 0, 'y': 1, 'z': 0}},
])

Note that all C ADMesh functions start with stl_ prefix and the Python methods of this module do not. Also note that not all C ADMesh functions are provided, because some would require more complicated approach and are not considered worthy. In case you are missing some functions, create new issue.
