In Java / Processing, I want to test whether a bezier curve is overlapping a circle, so that I can shift one of them out of the way.

Is there a simple way to do this?

You can use the `bezierPoint()`

function to get a series of points along a Bezier curve.

Then you could test those points against your circle.

From the reference:

noFill(); bezier(85, 20, 10, 10, 90, 90, 15, 80); fill(255); int steps = 10; for (int i = 0; i <= steps; i++) { float t = i / float(steps); float x = bezierPoint(85, 10, 90, 15, t); float y = bezierPoint(20, 10, 90, 80, t); ellipse(x, y, 5, 5); }
