OpenGeode-core

16.5.1 verified Fri May 01 auth: no python

OpenGeode is an open-source C++/Python framework for representing and manipulating geometric models, with a focus on mesh and boundary representation. Current version 16.5.1, active development with quarterly releases. Provides high-performance data structures and algorithms for geometric modeling.

pip install opengeode-core

Common errors

error ModuleNotFoundError: No module named 'OpenGeode' ↓

cause Importing with wrong capitalization (O instead of o).

fix

Use 'import opengeode' (lowercase).

error AttributeError: module 'opengeode' has no attribute 'TetrahedralSolid3D' ↓

cause Method name changed or not imported. Modern OpenGeode uses 'TetrahedralSolid3D' but may require loading extension.

fix

Ensure you have installed the full package and call 'opengeode.create_tetrahedral_solid3d()' or check documentation for correct class name.

Warnings

gotcha OpenGeode is primarily a C++ library with Python bindings; direct Python object manipulation may have unexpected performance overhead. Many operations are optimized for C++ usage. ↓

fix Use batch operations and avoid element-wise loops in Python.

deprecated The old 'import OpenGeode' (capital O) no longer works. Must use 'import opengeode' (lowercase). ↓

fix Change 'import OpenGeode' to 'import opengeode'.

breaking In version 16.0, the geometry module was reorganized. Functions like 'compute_distance' moved from opengeode.geometry to opengeode.core.geometry. ↓

fix Update imports: from opengeode.geometry to opengeode.core.geometry.

Imports

Quickstart

Create a 3D tetrahedral mesh with one tetrahedron.

import opengeode

# Create a 3D mesh
mesh = opengeode.TetrahedralSolid3D()
mesh.set_vertices([
    (0,0,0),
    (1,0,0),
    (0,1,0),
    (0,0,1)
])
mesh.add_tetrahedron([0,1,2,3])
print(f"Vertices: {mesh.nb_vertices()}")
print(f"Tetrahedra: {mesh.nb_tetrahedra()}")
