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 🙏

安装教程

yarn add @gridworld/te-cesium

使用说明

在导入te-cesium前,先导入Cesium,并将Cesium设置为window变量

/**
 * 点图元使用demo
 */
import * as TeCesium from "@gridworld/te-cesium";

// 定义点坐标
let position = Cesium.Cartesian3.fromDegrees(120, 30, 1000);
    
// 构建点entity的构造参数
let options = {

    dynamicMode: true, // 是否动态绘制,时变的对象可设为true,开启时显示性能会降低,如果对象基本不变请设为false
    viewer: window.viewer // cesium视图对象,必填
};

// 构建点entity
