GSoC Week 8, 9, 10

After a brief slowdown due to the start of college and on-campus internship drives (in which I secured an internship with DE Shaw & Co for Summer of 2026!), progress on SymPy’s WrappingCone is back on track.

WrappingCone Status

The core of the WrappingCone class is complete except for the geodesic_end_vectors method. All other methods, have been implemented and tested. Symbolic testing for geodesic_end_vectors remains to be added once the method is in place.

Example Models

With guidance from my mentor, I explored two example models to illustrate and test WrappingCone:

1. Cable car wrapping over a cone: derived contact lengths and draped segments, and shared the full derivation in LaTeX.
2. Conical pendulum

These examples will serve as regression tests and user tutorials.

Next Steps

• Code review feedback: address stylistic comments and improve docstrings.
• Complete geodesic_end_vectors and add symbolic tests for edge cases.
• Finalize tutorials and integrate them into the SymPy documentation.

Despite the early slowdown, Weeks 8–10 have laid the groundwork for a fully tested, documented, and merged WrappingCone.
