hypotrochoid - Plot hypotrochoids for spirographs with JavaScript

  •        40

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.

geo - S2 geometry library in Go

  •    Go

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.

Libcurve - An encryption and authentication library for ZeroMQ applications

  •    C

Curve 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.

bezier-easing - cubic-bezier implementation for your JavaScript animation easings – MIT License

  •    Javascript

BezierEasing provides Cubic Bezier Curve easing which generalizes easing functions (ease-in, ease-out, ease-in-out, ...any other custom curve) exactly like in CSS Transitions. 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.
