GPU.js

It is a cross-language, cross-platform application programming interface for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit, to achieve hardware-accelerated rendering.

Is the fastest 3D viewer for Windows, designed for engineers, designers, and 3D enthusiasts. View and interact with 3D model files ( JT, STEP, FBX, OBJ, GLTF, 3MF, STL) with unmatched speed. Load complex models up to 100x faster using our proprietary Wunder file format. Create cross-sections, measure accurately, and adjust colors or transparency with ease. Calculate volumes and craft custom views for technical documentation or presentations. Save models in the compact Wunder format for quick access and sharing. Ideal for engineering, manufacturing, and 3D modeling workflows. All files are processed locally, ensuring your data stays private and secure. Transform your 3D workflow with professional-grade tools and a user-friendly interface.

It is a JavaScript library which adds the HTML5 Canvas support to Internet Explorer. It renders shapes and images via Flash drawing API, and in many cases, runs faster than other similar libraries which use VML or Silverlight.
