Citybound: City building game, microscopic models to vividly simulate organism


A city building game that uses microscopic models to vividly simulate the organism of a city arising from the interactions of millions of individuals.

Each household maintains a precise real-time inventory of its resources, which not only include tangible goods like groceries, raw materials, or money, but also intangible concepts like sleep, health, recreation, work-force, touristic interests or business services. Compiling Kay to WebAssembly allows running a fully fledged actor system node in the browser, which can communicate with the simulation backend through type-safe high-performance messages and do computation-intensive preparation work for rendering, before efficiently serialising and passing rendering-relevant information as JavaScript objects to a React app that implements the rest of the UI. Early work has begun in my Michelangelo library that will provide expressive shape-grammars to describe architecture styles or natural shapes based on extrusions, which can then be evaluated on demand to generate optimally-batched meshes and instance-arrays with dynamic level of detail and animated components.
