🔒 Basic numpy arrays with triangles

[obsidian oxide]

Im trying to use numpy to create a polygon splitting algorithm that works like so:

1. Rectangle
2. For each side of the shape:
   take the midpoint of the ab edge
   extend the midpoint perpendicularly
   draw triangle from 3 points
3. Recurse until reached set recursion depth

My problem is that this is my first time using numpy and i find the dimension stuff super confusing, id love for someone to explain it to me based on what i already have written and this problem.

The error im getting now is in the pastebin, but i think the entire way im doing this has to be refactored i just dont know how.

Also the algorithm is flawed right now in terms of the math but i can change that myself after i understand how this triangle array should be done

py5 is a drawing library, the triangle function in it takes 3 xy points as arguments:
triangle(x1: float, y1: float, x2: float, y2: float, x3: float, y3: float, /) -> None

Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.
