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 🙏

在 Tiny 中渲染 3d 模型

查看demo

引用方法

  • 推荐作为依赖使用

    • npm install tinyjs-plugin-three --save
  • 也可以直接引用线上cdn地址,注意要使用最新的版本号,例如:

    • https://gw.alipayobjects.com/os/lib/tinyjs-plugin-three/0.1.0/index.js
    • https://gw.alipayobjects.com/os/lib/tinyjs-plugin-three/0.1.0/index.debug.js

起步

首先当然是要引入,推荐NPM方式,当然你也可以使用CDN或下载独立版本,先从几个例子入手吧!

1、最简单的例子

引用 Tiny.js 源码

<script src="https://gw.alipayobjects.com/os/lib/tinyjs/tiny/1.5.1/tiny.js"></script>
import * as Tiny3d from 'tinyjs-plugin-three';

const app = new Tiny.Application({
  showFPS: true, // 显示帧频
  width: window.innerWidth * 2,
  height: window.innerHeight * 2,
  forceCanvas: false,
  backgroundColor: 0x000000, // 画布背景色
  antialias: true,
});
document.body.appendChild(app.view);

// 加载 gltf
const loader = new Tiny.Loader();
loader.add('model', '../../assets/models/chicken/chicken.gltf');
loader.load((loader, resources) => {
  const model = Tiny3d.Model.from(resources['model'].gltf);
  parentNode.addChild(model);

  // 控制旋转
  model.rotationQuaternion.setEulerAngles(0, 180, 0);

  // 执行动画
  model.animations[1].loop = true;
  model.animations[1].play();
});
loader.onError.add((ex) => {
  // 加载失败,错误处理
});

2、开发辅助

import { GridHelper, AxesHelper } from '@tinyjs-plugin-three/helpers';
// 场景控制
new Tiny3d.CameraOrbitControl(app.view)

// 网格线
new GridHelper(model, [0, 0, 255]);

// 坐标轴
new AxesHelper(this);

3、模型调整

// 调整位置
model.position.x = 1;

// 缩放
model.scale.set(2);

// 旋转
model.rotationQuaternion.setEulerAngles(0, 180, 0);

4、光照调整

// 环境光
const ambientLight = Object.assign(new Tiny3d.Light(), {
  color: [1, 1, 1], intensity: 0.01, type: Tiny3d.LightType.ambient,
});

// 点光源
const pointLight = Object.assign(new Tiny3d.Light(), {
  x: 1.1, y: 0.2, z: 2.0, color: [1, 0, 0], intensity: 10, type: Tiny3d.LightType.point,
})

// 方向光
const directionalLight = Object.assign(new Tiny3d.Light(), {
  x: 0.2, y: 0.8, z: 2.0, intensity: 1, type: Tiny3d.LightType.directional,
})

// 聚光灯
const spotLight = Object.assign(new Tiny3d.Light(), {
  x: -0.7, y: 0.4, z: 2.0, color: [0, 0, 1], intensity: 20, outerConeAngle: 25, type: Tiny3d.LightType.spot,
})

// 添加
Tiny3d.LightingEnvironment.main.lights.push(ambientLight, pointLight, directionalLight, spotLight);

5、相机调整

const camera = Tiny3d.Camera.main;

// 进行调整
camera.position.set(...)
