git clone --recurse-submodules git@github.com:KrisYu/SharpEdge.git

Optimize Normals

Run opt_edges.py and it will show the usage.

Example:

python opt_edges.py sketch/onshape_simple_mouse.obj

With uv:

uv run --with-requirements requirements.freeze.minimal.txt --python 3.12 opt_edges.py sketch/onshape_simple_mouse.obj

Or run with visualization:

python opt_edges.py sketch/onshape_simple_mouse.obj --show-plot

With uv:

uv run --with-requirements requirements.freeze.txt --python 3.12 opt_edges.py sketch/onshape_simple_mouse.obj --show-plot

The optimized normals will be saved in:

data/normal/

(The directory will be created automatically if it does not exist.)

Generate the Surface

Build tools:

sh build_tools.sh

The following binaries will be compiled and placed in the data directory:

  • signed_heat_3d

  • cgal_remesh

  • cut_edges

Then run:

sh normal_to_mesh.sh data/normal/onshape_simple_mouse_2n.normal

Specify target edge lengths for surface generation and target length for remesh:

sh normal_to_mesh.sh data/normal/bowl_curve_2n.normal 0.05
sh normal_to_mesh.sh data/normal/bowl_curve_2n.normal 0.06 0.02
  • 2nd argument: TARGET_EDGE_LENGTH (default: 0.04)
  • 3rd argument: TARGET_REMESH_LENGTH (default: 0.015)

All generated surface results will appear in:

data/onshape_simple_mouse/
