Creates a simple box mesh, converts to half-edge representation, and prints face count.

from pygel3d import Mesh, hmesh # Create a simple mesh (a box) box_mesh = Mesh() box_mesh.add_vertex([0,0,0]) box_mesh.add_vertex([1,0,0]) box_mesh.add_vertex([1,1,0]) box_mesh.add_vertex([0,1,0]) box_mesh.add_face([0,1,2,3]) # Convert to half-edge mesh hm = hmesh.Manifold.from_mesh(box_mesh) print("Number of faces:", hm.num_faces())

Debug

Known issues

breakingThe import path changed from 'pygel' to 'pygel3d' starting with version 0.6.0. Old code using 'import pygel' will fail.

fix

Replace 'import pygel' with 'import pygel3d' and update all submodule references accordingly.

affects: >=0.6.0

gotchaMesh simplification functions expect a hmesh.HalfedgeMesh object, not a raw Mesh. Passing a Mesh will cause AttributeError.

fix

Convert Mesh to half-edge mesh using hmesh.Manifold.from_mesh() before calling simplify functions.

affects: all

deprecatedThe 'gl_display' module relies on PyOpenGL and may be removed in future releases as the library moves to headless processing.

fix

Use external visualization libraries (e.g., trimesh, polyscope) instead of gl_display.

affects: <=0.6.1
