    Delaunator

    Delaunator

    Fast JavaScript library for Delaunay triangulation of 2D points

    Delaunator is a fast library for Delaunay triangulation. It takes as input a set of points. The triangulation is represented as compact arrays of integers. It’s less convenient than other representations but is the reason the library is fast. After constructing a delaunay = Delaunator.from(points) object, it will have a triangles array and a halfedges array, both indexed by half-edge id. What’s a half-edge? A triangle edge may be shared with another triangle. Instead of thinking about each...

    Image processing algorithms in pure Go

    A collection of parallel image processing algorithms in pure Go. The aim of this project is simplicity in use and development over absolute high performance, but most algorithms are designed to be efficient and make use of parallelism when available. It uses packages from the standard library whenever possible to reduce dependency use and development abstractions. All operations return image types from the standard library. Package convolution provides the functionality to create and apply a...

    React Three Fiber

    React Three Fiber

    A React renderer for Three.js

    Build your scene declaratively with re-usable, self-contained components that react to state, are readily interactive, and can tap into React's ecosystem. There is no hard dependency on a particular three.js version, it does not wrap or duplicate a single three.js class. It merely expresses three.js in JSX, <mesh /> becomes new THREE.Mesh(), and that happens dynamically. There is no additional overhead. Components participate in a unified render loop outside of React. It outperforms three.js...

    PINRemoteImage

    PINRemoteImage

    A thread safe, performant, feature rich image fetcher

    PINRemoteImageManager is an image downloading, processing and caching manager. It uses the concept of download and processing tasks to ensure that even if multiple calls to download or process an image are made, it only occurs one time (unless an item is no longer in the cache). PINRemoteImageManager is backed by GCD and safe to access from multiple threads simultaneously. It ensures that images are decoded off the main thread so that animation performance isn't affected. None of its exposed...

    Decorators/view-models for Rails applications

    Draper adds an object-oriented layer of presentation logic to your Rails application. Without Draper, this functionality might have been tangled up in procedural helpers or adding bulk to your models. With Draper decorators, you can wrap your models with presentation-related logic to organize and test this layer of your app much more effectively. Imagine your application has an Article model. With Draper, you'd create a corresponding ArticleDecorator. The decorator wraps the model, and deals...

    uPlot

    uPlot

    Chart for time series, lines, areas, ohlc and bars

    μPlot is a fast, memory-efficient Canvas 2D-based chart for plotting time series, lines, areas, ohlc & bars; from a cold start it can create an interactive chart containing 150,000 data points in 135ms, scaling linearly at ~25,000 pts/ms. In addition to fast initial render, the zooming and cursor performance is by far the best of any similar charting lib; at ~40 KB, it's likely the smallest and fastest time series plotter that doesn't make use of context-limited WebGL shaders or WASM, both...

    A renderer agnostic two-dimensional drawing api for the web

    Two.js is a two-dimensional drawing api geared towards modern web browsers. It is renderer agnostic enabling the same api to draw in multiple contexts: svg, canvas, and webgl. Two.js is deeply inspired by flat motion graphics. As a result, two.js aims to make the creation and animation of flat shapes easier and more concise. At its core two.js relies on a scenegraph. This means that when you draw or create an object (a Two.Path or Two.Group), two actually stores and remembers that. After you...

    ...Ensure that the Analytics Blueprints Plugin is enabled. You can either enable it in the Plugins browser in the Unreal Editor or by modifying the project file. Close the Unreal Editor and re-open it through the Epic Games Launcher. You should be prompted to recompile your project and the cognitiveVR Plugin. If the plugin is loaded correctly, it should be visible in the Plugins window. You will need to have your Developer Key and Application Key from the Dashboard. You will also need to have Blender installed. Blender is free and open-source, we use this to automatically convert images exported from Unreal Engine.

    Types, addon system, UI models, core logic

    Stremio Core is the Rust engine that powers Stremio’s apps by centralizing all reusable logic behind discovery, catalogs, metadata, streams, add-ons, and user/library state. It exposes a clean set of modules—types, addon_transport, and state_types—so apps can talk to add-ons, model UI state, and react to events without duplicating code. The architecture is inspired by Elm: immutable state, message-driven updates, and explicit side-effects (“effects”) keep behavior predictable and testable....

    Browser extension for rendering isometric pixel art charts

    This is a browser extension for Chrome/Brave and Firefox that lets you toggle between your regular GitHub contribution chart and an isometric pixel art version. It uses obelisk.js for isometric graphics. Besides being sort of neat looking, this view is interesting in that it highlights the differences between the number of contributions with more granularity. This isn't meant to completely replace the standard 2D graph though, because in most ways it is actually less useful. For example,...

    Mesh R-CNN is a 3D reconstruction and object understanding framework developed by Facebook Research that extends Mask R-CNN into the 3D domain. Built on top of Detectron2 and PyTorch3D, Mesh R-CNN enables end-to-end 3D mesh prediction directly from single RGB images. The model learns to detect, segment, and reconstruct detailed 3D mesh representations of objects in natural images, bridging the gap between 2D perception and 3D understanding. Unlike voxel-based or point-based approaches, Mesh...
