This talk demonstrates how to reuse existing Rust backend functionality in a web application by using @webassembly1232. Georg Semmler and Jonas Klein of @gigainfosystems showcase a real-world project involving geological subsurface models, where computationally expensive calculations were successfully implemented in both the backend and 3D web viewer using Rust. This talk showcases the required procedure based on a real world project. As part of a #database and #visualization system for #geological subsurface models, Semmler and Klein had pre-existing functionality to generate a virtual borehole through potentially large models. This functionality is implemented in Rust and was previously used in backend code. As part of another project, the team sought to reuse these computationally expensive calculations in their 3D web viewer for calculating information based on the current content displayed. Oxidize Conference is the applied Rust conference in Berlin, Germany. Oxidize Conference 2025 will be held from September 16 through September 18 at Tagungswerk in Berlin.
