Returns points across one or more hypotrochoids for varying values of t.Trivia: you can trace out curves like this using a spirograph, yielding similar results to Guilloché machines - which were used to create intricate patterns resistant to counterfeiting.

verb is a library for creating and manipulating NURBS surfaces and curves in many languages including JavaScript. verb provides advanced tools like derivative evaluation, adaptive tessellation, and intersection. Verb provides a concurrent execution runtime via WebWorkers in modern browsers and thread pools on other platforms and is suitable for use in a datacenter or in the browser.

ec elliptic curve cryptographyAndroid library that adds a curve at the below of image views and relative layouts. CrescentoImageView and CrescentoContainer are the image view and relative layout respectively. You can change the radius of curve with attribute:curvature. Here is a very good example of how to use Crescento. Zsolt Szilvai has made a very good design and I've illustrated using crescento.

I've discovered the curve modifier in Blender and really love it. People on Twitter went crazy with the gif below, so I always wanted to share how to do it.

This is a library for manipulating geometric shapes. Unlike many geometry libraries, S2 is primarily designed to work with spherical geometry, i.e., shapes drawn on a sphere rather than on a planar 2D map. (In fact, the name S2 is derived from the mathematical notation for the unit sphere.) This makes it especially suitable for working with geographic data.Basic representations of angles, intervals, latitude-longitude points, unit 3D vectors, and conversions among them.

data-management geometry-api-javaCurve implements the CurveZMQ elliptic curve security mechanism, for use in ZeroMQ applications. This library is primarily a reference implementation for the CurveZMQ specification but may also be used for end-to-end security. CurveZMQ creates encrypted sessions ("connections") between two peers using short term keys that it securely exchanges using long term keys. When the session is over, both sides discard their short term keys, rendering the encrypted data unreadable, even if the long term keys are captured. It is not designed for long term encryption of data.

Implementing efficient lookup is not easy because it implies projecting the X coordinate to a Bezier Curve. This micro library uses fast heuristics (involving dichotomic search, newton-raphson, sampling) to focus on performance and precision.

By setting eight parameters (Of course you don't have to set every because they all have default value), WJMagicCurveView will draw a beautiful curve based on a math function.
