Cosmos Journeyer

Cosmos Journeyer is an infinite procedural universe with billions of believable star systems accessible right inside your browser. Each planet is fully explorable from orbit with your spaceship to the surface on foot, without any loading screen.

Asset Scattering

Simulation of millions of grass blades at interactive rates using compute shaders with instancing. The scattering technique extends beyond grass blades to animate butterflies as well as trees, and can also wrap around planets like in Cosmos Journeyer.

Ocean simulation

This ocean simulation uses compute shaders with WebGPU to achieve real-time animation, with a high visual fidelity. The technique is based on Jerry Tessendorf's original paper, using fast fourier transform to simulate the wave spectrum. It was made at Telecom Paris for my 2nd year of Master.

Rigidbody Physics

Avalanche is a 3D rigidbody physics engine that runs in the browser. It was made at Telecom Paris for my 1st year of Master. Avalanche comes with many optimizations such as broad phase detection, rest detection and spatial hashgrids.

Soft body physics

A C++ implementation of both XPBD and HPBD papers for fast and accurate soft body simulations of any objects. It was made at Telecom Paris during my 2nd year of Master.

Liquid Simulation

A 3D fluid simulation pipeline created at Telecom Paris for my 1st year of Master. It simulates the fluid using the IISPH method then generates a volume using the industry standard OpenVDB so that it can be rendered using Blender Cycles.

Github

Cloth Simulation

A small spring-based cloth simulation that runs in the browser. It is based on opencloth and can react to collisions with spheres.

Boids

Boids is a simulation of flocking behavior. The goal is to create a swarm of birds that can fly together in a realistic manner with collision avoidance and group behavior.

Orbital Mechanics

A simulation of orbital mechanics using Newton's laws or Kepler's laws of celestial motion. While Newton gives a more realistic outcome, you might prefer Kepler's laws for their stability.

Drawing application

A paint like application built with Qt to draw geometric shape and edit them. It was made for my first year of master at Telecom Paris.

Github

Movie Center

An Electron application that allows you to organize your movies on your computer with ease. You can mark movies as favorites and movie posters are retrieved automatically from the internet.
