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 🙏

Readme

@kmax/three-stereo

面向 Three.js 的 Kmax 立体显示 SDK,提供左右并排立体渲染、Kmax 投影矩阵写入、WebSocket 追踪转导,以及触控笔射线交互。

安装

npm install @kmax/three-stereo three

three 是对等依赖,需要由接入方应用安装。框架无关的投影和追踪能力来自 @kmax/stereo-core,会随本包自动安装。

基本用法

import {
  KStereoEffect,
  WSTrackClient,
  createKmaxFrustumProvider,
} from '@kmax/three-stereo';

const frustumProvider = await createKmaxFrustumProvider();

const effect = new KStereoEffect(renderer, { frustumProvider });
effect.setSize(window.innerWidth, window.innerHeight);

const track = new WSTrackClient();
track.onData = (data) => {
  camera.position.set(data.eye.pos.x, data.eye.pos.y, -data.eye.pos.z);
};

需要立体输出时调用 effect.render(scene, camera);普通单眼渲染仍使用 renderer.render(scene, camera)

追踪客户端

import { WSTrackClient } from '@kmax/three-stereo';

const track = new WSTrackClient({
  onStatusChange(status) {
    if (status === 'connected') {
      // 当前设备可用 Kmax 追踪服务,可启用立体显示模式。
    }

    if (status === 'unavailable') {
      // 未检测到追踪服务,应用应保持普通渲染。
    }
  },
});

WSTrackClient@kmax/stereo-core 转导,默认自动连接 Kmax 追踪服务。
