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>

Folder Structure
docs
- this is the root folder for the GitHub page athttps://vimaec.github.io/vim-webgl-viewer
. Thedocs\index.html
file is meant to demo the latest stable patch release, while thedocs\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 thebuild
script:dist\vim-webgl-viewer.es.js
- an EcmaScript moduledist\vim-webgl-viewer.es.js.map
- Typescript source map file map for the EcmaScript moduledist\vim-webgl-viewer.iife.js
- an immediately-invocable function expression (IIFE) intended for consumption from a web-pagedist\vim-webgl-viewer.iife.js.map
- Typescript source map file map for the IIFEtypes\
- 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 Vitebuild
- compiles an IIFE JavaScript module and ES module using Vite and the configuration file, placing the output in thedist
folderserve-docs
- launches a web server with thedocs
folder as the root folder, for testing a published NPM package (tagged develop or latest) locallyeslint
- runs ESLint and reports all syntactic inconsistenciesdocumentation
- generates API documentation atdocs/api
declarations
- generates TypeScript declarations atdist/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.
