Unlocking the Potential of Reusable Code with WebAssembly

on YouTube ↗31m

" summary

Reuses existing Rust backend calculations by compiling them to WebAssembly with @webassembly1232 and exposing functions via annotated bindings, runs them inside web workers using Comlink and shared ArrayBuffers to avoid copying geometry. Demonstrates real project handling up to millions of triangles and gigabytes of model data, reports small-model timings around 1 ms in Rust/WASM vs ~7 ms in JS, finds backend round trips much slower, and documents memory limits and target-specific stdlib issues that required conditional compilation and data-structure optimizations.
