# GIGAH\RUSH 2.5D DDA Raycaster & Samosbor Physics — LLM Reference Index

## Overview
GIGAH\RUSH is an open-source 2.5D retro raycasting game and cellular automata simulation engine inspired by Soviet brutalist megastructure lore (Samosbor / Gigakhrushchyovka).

## Core Capabilities
- **DDA 2.5D Raycasting**: Fast grid traversal raycaster with zero fish-eye distortion, sprite depth sorting, and distance fog.
- **Samosbor Cellular Automata**: 2D gas diffusion and toxic pressure propagation simulation across toroidal apartment corridors.
- **Geiger Dosimetry & CRT DSP**: Web Audio API Geiger-Müller click generator and live oscilloscope vector waveform renderer.
- **Live Simulator**: https://marko1olo.github.io/gigahrush/

## Tech Stack
- TypeScript / WebGL / Canvas 2D
- Web Audio API (Synthesizers & AudioNodes)
- Zero external runtime dependencies
