Crescento - Add curve at bottom of image views and relative layouts.

•    Java

---

Android 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.

verb - Open-source, cross-platform NURBS

•    Javascript

---

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.

key-encoder-js - Library for encoding and decoding ecdsa private keys and converting between formats

•    Javascript

---

To get started, first define your key encoder and raw private/public keys.As shown above, there is built in support for SECP256k1 (the curve Bitcoin uses), but you can pass in your own curve parameters for any curve you'd like.

bezier - n-degree Bezier spline interpolation.

•    Javascript

---

n-degree Bezier curve interpolation.Returns the value at t for a bezier curve of points.length degrees. In other words, if you pass it a 3-element array you'll get the results of a 3-degree (quadratic) curve.

hypotrochoid - Plot hypotrochoids for spirographs with JavaScript

•    Javascript

---

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.

adaptive-bezier-curve - adaptive and scalable 2D bezier curves

•    Javascript

---

Builds a bezier curve that is adaptive; that is to say, it has more points along curved corners, and less points along straight lines. This can be used to produce scalable curves that are consistently smooth, while using a small number of steps. Based on AntiGrain.Also see adaptive-quadratic-curve.
