Could you build this?
Partial Building multi-scale procedural generation (continents down to tactical battlemaps) in Rust/WASM rendered via PixiJS involves intricate procedural algorithms and performant memory management across the WASM boundary.
What it would actually take: The architecture combines a Rust core compiled to WebAssembly for deterministic procedural world generation (Voronoi/Delaunay tessellations, plate tectonics simulation, biome distribution, and cellular automata for battlemaps) paired with Svelte and PixiJS for GPU-accelerated rendering. The difficult aspect is writing robust, performant hierarchical generation algorithms that maintain spatial coherence across massive scale changes without running into browser memory or frame rate bottlenecks. It requires expertise in computational geometry, procedural noise algorithms, and WebAssembly-JavaScript interop.
