Python Mesh Library

Feature

  • Supported format

    • STL(Binary, ASCII)
    • OBJ(Wavefront, no material supported)

  • Transform

    • Translate
    • Rotate
    • Scale

  • Join

  • Analyze

    • Volume

  • Numpy is used for inner calculation so that it runs fast.

Install

pip install pymesh

Requirement

numpy is required.

Usage

Load data

# STL
from pymesh import stl
m = stl.Stl("sample.stl")

# OBJ
from pymesh import obj
m = obj.Obj("sample.obj")

Save data

# STL
m.save_stl("out.stl")

# OBJ
m.save_obj("out.obj")

Create empty data

# STL
m = stl.Stl()

# OBJ
m = obj.Obj()

Transform

# Translate
m.translate_x(10)

# Rotate
m.rotate_y(30)

# Scale
m.scale(1, 2, 1)

# Method chain supported
m.translate_x(10).rotate_y(30).scale(10, 1, 1)

Join

  • Combine multiple mesh data into one mesh
# Join
m.join(another)

Analyze

# Volume
m.get_volume()

Support

  • Python 2.7+ and Python 3 are both supported
