kyletimmermans / CircleEdgePoint.py
Last active April 10, 2024 13:58
The Python code and math for finding the coordinates of a point on the edge of a circle where a line between two points intersects on the circle, the two points being: the center of the circle (A) and the point outside of the circle (B). This math can be used to draw a line cleanly from the edge of a circle without it overlapping the circle itself.
from math import sqrt

def circle_edge_point(x1, y1, x2, y2, r):
try:
cx = x1 + (r * (x2 - x1) / sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2))
except ZeroDivisionError:
# Add 0.0001 if divisor is 0
cx = x1 + (r * (x2 - x1) / sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2) + 0.0001)
