Overview

The Laser Defense System is a simulation project that explores the idea of using directed-energy weapons to intercept and neutralize incoming threats. I've created a complete runthrough blog posts of the project.
except for the real physics based trajectory which I will add later on so I've used a simple trajectory in the blog.

The idea

Aiming to simulate real missile trajectory and also to visualizes how a laser unit could:

  • Detect incoming targets
  • Track their trajectory
  • Allocate energy to intercept them before impact

Tech Stack

Three.JS + React (using R3F and Drei in Vite) , Tailwind , Zustand
