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 🙏

Overview

The VIM WebGL Viewer is an open-source high-performance 3D model viewer that specializes in loading extremely large AEC (Architectural/Engineering/Construction) models represented as VIM files.

It is built on top of the popular Three.JS WebGL framework to provide commonly used AEC related features. It can be simply included via script tags or consumed using esm imports.

The VIM file format is a high-performance 3D scene format that supports rich BIM data, and can be easily extended to support other relational or non-relation data sets.

Unlike IFC the VIM format is already tessellated, and ready to render. This results in very fast load times. Unlike glTF the VIM format is faster to load, scales better, and has a consistent structure for relational BIM data.

More information on the vim format can be found here: https://github.com/vimaec/vim

Using the Viewer from a Web Page

The following is an example of the simplest usage of the VIM viewer:

<html>
  <head>
    <title>VIM Viewer</title>
  </head>
      <style>
      /*Makes full screen and remove scrollbars*/
      html,
      body {
        height: 100%;
        margin: 0;
        padding: 0;
        overflow: hidden;
        /*This prevents touches from being eaten up by the browser.*/
        touch-action: none;
      }
    </style>
  <body>
    <script src="https://unpkg.com/[email protected]"></script>
    <script src="https://unpkg.com/[email protected]"></script>
    <script>
    
      async function load(){
        // Create a new viewer. 
        const viewer = new VIM.Viewer()

        // Open the vim file.
        const vim = await VIM.open(
          'https://vim02.azureedge.net/samples/residence.v1.2.75.vim',
          {
            rotation: new VIM.THREE.Vector3(270, 0, 0)
          }     
        )
          
        // Load all geometry from vim file.
        await vim.loadAll()

        // Add loaded vim to the viewer.
        viewer.add(vim)

        // Immediately frame loaded vim.
        viewer.camera.snap().frame(vim)
      }
      
      // Need function because you can't have top level async
      load()
      
    </script>
  </body>
</html>

Running Locally

  • Checkout repo
  • Run npm install to install all dependencies
  • Run npm run dev to launch a dev-server and watch for change
  • Navigate to the indicated localhost url in your browser

Folder Structure

  • docs - this is the root folder for the GitHub page at https://vimaec.github.io/vim-webgl-viewer. The docs\index.html file is meant to demo the latest stable patch release, while the docs\index-dev.html Is meant to test the latest dev release.
  • src - contains the TypeScript source code for the viewer.
  • dist - created by running the build script for creating a distributable package. It contains five items after running the build script:
    • dist\vim-webgl-viewer.es.js - an EcmaScript module
    • dist\vim-webgl-viewer.es.js.map - Typescript source map file map for the EcmaScript module
    • dist\vim-webgl-viewer.iife.js - an immediately-invocable function expression (IIFE) intended for consumption from a web-page
    • dist\vim-webgl-viewer.iife.js.map - Typescript source map file map for the IIFE
    • types\ - A folder containing Typescript type declarations for the package.

Scripts

The following scripts are defined in the package.json, and can each be executed from within VSCode by right-clicking the script name, or from the command line by writing npm run <script-name> where <script-name> is the name of the script:

  • dev - launches a development environment using Vite
  • build - compiles an IIFE JavaScript module and ES module using Vite and the configuration file, placing the output in the dist folder
  • serve-docs - launches a web server with the docs folder as the root folder, for testing a published NPM package (tagged develop or latest) locally
  • eslint - runs ESLint and reports all syntactic inconsistencies
  • documentation - generates API documentation at docs/api
  • declarations - generates TypeScript declarations at dist/types"

Contributing:

  • Source code is formatted using prettier-eslint using the standardjs format.
  • On VSCode it is recommended to install ESLint and Prettier ESLint extensions.

The Sources and Dependencies

The distributable files do not contain the underlying source for Three.JS to avoid duplication. Please include Three.JS on your own.
