Highlights

Ultimate Fluid Sim

Ultimate Fluid Sim is a fluid simulation that makes use of the Smoothed Particle Hydrodynamics method. Built from scratch, it is capable of simulating multiple liquids with different viscosities and densities, gasses, and interactions with solids. It features many optimizations to speed up the simulation, such as positional hashing. It uses the Runge-Kutta 4th order integration method, rather than the Explicit Euler method, which allows for much greater simulation accuracy.

Ant Colonies

An implementation of Kenneth Stanley's NeuroEvolution of Augmenting Topologies (NEAT). In this implementation, ant colonies compete against each other for food. The best colonies produce similar colonies, making the colonies progressively better. It is able to simulate fighting, food, pheromones, offspring, and nest raids.

motus.

A wheelchair controlled with your eyes, submitted to Hack the North 2023. All circuitry, code, and construction was built in the span of 34 hours, from an office chair and provided eye-tracking glasses.

Mr. V Simulator

Mr. V Simulator is a first person stamper game (because g*ns are not school appropriate). It uses a 3D engine built from scratch, which uses raycasting. Navigate through a maze, and make it to the next level, while stamping assignments with Mr. V's stamp of approval. Make sure not to let the assignments get too close! The maze generation algorithm is entirely original. Your score increases with every assignment stamped, based on your current level.

ShopDog is the 2nd place submission for NeoDeveloper League 2024. It is a comprehensive system for cashierless stores, using RFID to scan the items in a cart, and using Stripe to handle payment. It also tracks stock, saving small store owners hours of labour costs that come with manually counting stock. The project, created in 10 hours, makes these technologies used by big warehouses, and multi-million dollar companies, more accessible to small businesses, leveling out the playing field, and helping the underdogs.
