Clothoid

✓ from pyclothoids import Clothoid

✗ from clothoid import Clothoid

Package name is pyclothoids, not clothoid

Create a clothoid curve using G1 Hermite interpolation and sample points.

from pyclothoids import Clothoid # Create a clothoid from start and end states x0, y0, theta0 = 0.0, 0.0, 0.0 # start x1, y1, theta1 = 10.0, 5.0, 1.0 # end clothoid = Clothoid.G1Hermite(x0, y0, theta0, x1, y1, theta1) # Sample points along the clothoid points = clothoid.SampleXY(100) print(points)

Debug

Known issues

gotchaThe Clothoid class is not exported; use Clothoid.G1Hermite (or other class methods) to create instances. Direct instantiation with Clothoid() will fail.

fix

Always use a factory class method like Clothoid.G1Hermite(...), Clothoid.G2Hermite(...), or Clothoid.BiArclength(...).

affects: all

gotchaThe library is not yet stable; API may change between minor versions. Version 0.2.0 introduced new methods like ClosestPoint and Distance, but existing code may break if it relied on internal attributes.

fix

Check the changelog and adapt calls if upgrading from 0.1.x. Use the public API documented in the README.

affects: <=0.2.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'clothoid'

Incorrect import path; the module is named pyclothoids, not clothoid.

fix

Use 'from pyclothoids import Clothoid' or 'import pyclothoids'.

TypeError: 'ClothoidType' object is not callable

Attempting to create a Clothoid by calling Clothoid() directly, but the class requires a factory method.

fix

Use Clothoid.G1Hermite(...) or other class methods to instantiate.
