Hypocycloid patterns
Web10 apr. 2024 · Hypotrochoid is a curve very similar to Hypocycloid. But it is more general than Hypocycloid because the point we are tracing doesn’t have to lie on the circle. It can be inside or outside the circle, making it possible to create more interesting curves. The following is a few Hypotrochoid curves created with Python Turtle: WebPropagation Patterns in Excitable Media Tatsunari Sakurai, Eugene Mihaliuk, Florin Chirila, Kenneth Showalter* ...

Web4 jan. 2016 · The hypocycloid is a curve obtained by rolling a circle of radius b inside the circumference of a larger circle of radius a and tracing the path of a fixed point P on the smaller circle of radius b (a visual depiction of this rolling can be found in Fig. 1 for the tricuspoid where a/b=3 ). These curves can be represented in parametric form as Web24 mrt. 2024 · The astroid can also be formed as the envelope produced when a line segment is moved with each end on one of a pair of perpendicular axes (e.g., it is the curve enveloped by a ladder sliding …
In geometry, a hypocycloid is a special plane curve generated by the trace of a fixed point on a small circle that rolls within a larger circle. As the radius of the larger circle is increased, the hypocycloid becomes more like the cycloid created by rolling a circle on a line.

WebWikipedia tells me this is similar to something called a hypocycloid - except in a hypocycloid the arcs come to points on the edge of the enclosing circle. Here, the line continues and and loops around itself before continuing the hypocycloid pattern. I'd like to draw versions of this with 4 & 5 lobes, and be able to control the various parameters.
