How We Built Size.link - Shopify

What this post added

This post details the development of Size.link, a web-based AR tool for visualizing product dimensions. It describes the technical challenges of implementing AR on the web across iOS and Android, the differences between AR Quick Look and Scene Viewer, and the intricacies of 3D file formats like glTF and USDZ. The core technical contribution lies in the innovative approach of directly manipulating the binary data of USDZ files to dynamically adjust scale and vertex positions, bypassing the need for heavy conversion tools and enabling fast, on-the-fly AR model generation. This approach was crucial for achieving a seamless user experience without requiring a dedicated mobile application.
