e57

E57 Python Library

E57 is a compact, non-proprietary point cloud format that's defined by the ASTM E2807 standard. This format is widely adopted by 3D design applications.

This python library wraps the rust e57 library to provide file reading

• Proof of concept xml reading
• Read e57 point coordinates to numpy array - see read_points method.
• Read color field to numpy array.
• Read intensity to numpy array.
• Read other fields to numpy array.
• Write to e57 (format ?)

Getting Started

pip install e57

>>> import e57
>>> pc = e57.read_points(r"pointcloud.e57")
>>> pc.points
array([[-23.25304444, -28.17607415, -13.44830654],
       [-23.28290139, -28.02118905, -13.44237764],
       [-23.26799723, -27.9039115 , -13.43430738],
       ...,
       [ 23.2458152 ,  25.4866642 ,  12.45043932],

       [ 23.25270363,  25.45909652,  12.54284554]])
>>> pc.color
array(([0.3019608 , 0.3529412 , 0.23137255],
       [0.21176471, 0.26666668, 0.12941177],

       [0.41568628, 0.43529412, 0.33333334],
       [0.21568628, 0.25882354, 0.1254902 ]], dtype=float32)

We need a tutorial - could you write one based on our tests?
