Draco Compression of GLB Files - 87% Size Reduction and Impact on Precision
When delivering 3D models on the web, file size is a critical concern. This article describes a case where Draco compression was used to reduce a GLB file by 87%, along with precautions during compression (particularly regarding UV coordinates). https://3dtiles-viewer.vercel.app/glb-viewer.html Data Used Model: Rotunde Brunnen (a rotunda with a fountain) Source: Sketchfab Format: GLB (glTF 2.0 Binary) What is Draco Compression? Draco is an open-source 3D mesh compression library developed by Google. It is supported as a standard extension in glTF 2.0 as KHR_draco_mesh_compression. ...
