glTF Extension Format with LOD and WebGL 3D Visualization Platform

Key Points

A new web platform efficiently renders glTF models, enhancing performance across various devices.
It integrates Level of Detail (LOD) techniques, improving the handling of complex 3D mesh models.
Tools for generating glTF files with EXT_lod tags are developed to address original specification limitations.
This work highlights the need for enhanced LOD support in glTF for better web-based application performance.

Abstract

This paper proposes an advanced web platform for rendering glTF models with Level of Detail (LOD) information, presenting an efficient technique for handling complex 3D mesh models containing extensive geometric and visual data. While glTF™ has emerged as a powerful API-neutral asset format optimized for efficient transmission and loading of 3D scenes and models, its original specification lacked native LOD support, creating significant limitations for web-based applications where bandwidth and processing capabilities vary widely across devices. Our research develops tools for generating glTF files containing EXTₗod tags based on Microsoft
