Python Changes

Explicit support for Python 3.8 has been added (#161). On Windows this required using the os.add_dll_directory() function to load bezier.dll (in earlier Python versions, the DLL directory was added by modifying %PATH%).

Loosened type constraints in Curve constructor and Surface constructor; now any sequence type is accepted rather than only NumPy arrays (68f7dc7, a8c68a3, f5c7869). Fixed #146.
Added copy and verify arguments to Curve constructor and Surface constructor (#163). Fixed #158.
Added SymPy-based helpers for “exact” representations (#164). Fixed #157.
- Curve.implicitize() function
- Curve.to_symbolic() function
- Surface.implicitize() function
- Surface.to_symbolic() function

Re-factored non-public modules so that algorithms implemented in pure Python only invoke other algorithms written in pure Python (#160). Previously these algorithms invoked the equivalent Fortran speedup if present for a given function. Fixed #159.

Changed all [in] arguments in C headers to const pointers (#169). Fixed #168.

Explicitly handle length 0 curves (with an error) in the compute_length() Fortran subroutine that is used by the Curve.length property (a24368f). Fixed #148.
Fixed high-degree error in the Curve.evaluate() method, via the evaluate_curve_barycentric() Fortran subroutine (5768824). Fixed #156. The code uses \(\binom{n}{k + 1} = \frac{n - k}{k + 1} \binom{n}{k}\) to update the value and \((30 - 14) \binom{30}{14}\) overflows a 32-bit signed integer.

Updated install instructions to show how to disable the binary extension via BEZIER_NO_EXTENSION (6262594, 00c1e61). Fixed #147.
Added “Citation” section to landing page (9885063). Fixed #150.
