Utilities to slice 3D triangular meshes.
Project description
For now, this computes the planar cross-section of a 3D mesh.
Given a 3D mesh and a cut plane, this computes a (set of) polyline(s) that results from cutting the mesh with the plane.
Requires python and numpy. Mayavi is used for visualisation in the examples.
Usage
Run the examples with
python examples/cross_section.py
