The VIM for WebGL application is an open-source high-performance 3D model viewer built on top of the popular Three.JS WebGL framework that specializes in loading extremely large AEC (Architectural/Engineering/Construction) models represented as VIM files.

The VIM WebGL application combines the Three.JS library with several common loaders and utilities, to reduce boilerplate code. 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.
