# A small shapely example for class
# A translucid circle and triangle intersect
# On the right, the intersection of them, and the triangle with the circle overlap clipped of.

Similar to yesterday's sketch, but I removed all dependency of my old awkward
helper functions. I'm now using just shapely and Py5Vector rotation and lerp.

Has anyone tried the dark arts of converting #SVG to #shapely recently? :(

#Python

Debugging a complex Python library via a Jupyter notebook is unfairly good tech, yinz.

Now that I've tried it, I can't go back.

My favorite part of this exercise?

Testing the fix in-place by copying the broken method out of the class, editing it, monkey-patching it back into the class definition, and then re-running the small verification setup I threw together in Jupyter. Newly-created class instances are using the new method and the flow goes from "Busted" to "Working."

(Plus, Jupyter supports matplotlib output, which is huge when what I'm debugging is fundamentally geometric in nature).

Finally a new #Shapely feature release! 🎉
Shapely 2.1.0 highlights include initial support for geometries with M or ZM values, functionality for coverage validation and simplification, and a set of other new top-level functions.

For a full overview, see https://shapely.readthedocs.io/en/latest/release/2.x.html#version-2-1-0
