Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

2gl Build Status Coverage Status

Узкоспециализированная библиотека WebGL для использования в проектах 2GIS

Документация

  • Для работы с матрицами и векторами используется библиотека glMatrix
  • Работа с геометрическими объектами, например, Plane, Line3, Ray, взята из three.js

На данный момент может работать со следующими типами объектов для отображения:

  1. Basic mesh - меш, закрашивается в один цвет
  2. Complex mesh - меш, для которого можно установить: цвета для каждой из вершин, освещение, текстуру и определять для какой из вершин будет использоваться текстура
  3. Sprite - спрайт, к камере расположен всегда одной гранью, удалённость не влияет на размеры изображения
  4. MultiSprite - мультиспрайт представляет собой множество спрайтов, которые рисуются в один draw call

Examples

Установка

  • npm install 2gl

Подключение

Есть несколько способов подключения библиотеки:

  • Напрямую через тег, скрипт 2gl.js лежит в папке dist и содержит все компоненты библиотеки:
<script src="2gl.js"></script>
  • Если вы используете сборщики, например, browserify или webpack:
var dgl = require("2gl"); // CommonJS
import dgl from "2gl"; // ES6
  • Можно подключать только нужные компоненты для уменьшения размера:
var Mesh = require("2gl/Mesh");
var AmbientLight = require("2gl/lights/AmbientLight");

Development

  • npm install
  • npm start

Checking examples locally

  • Install http-server
  • Run http-server at the root project directory
  • Open http://localhost:8080/ and navigate to some *.html demo at the examples directory

Release

If you plan to release a new version from your branch

  • Bump version via npm version major | minor | patch
  • Merge your branch into master
  • Create a new release, this will run the release workflow

Beta-release

Beta-release is suitable to perform some checks/integrations with npm-package.

It releases the same npm package as a regular release, but in the beta tag, which do not update latest version on npm.

To make beta-release you should create a tag with a current version in package.json and suffix, e.g.

npm version 0.12.0-foo-bar

And then push tag.

git push --tags

Pushed tag will run the beta-release workflow.
