Falling Sand Simulation

A WebGPU-based falling sand simulation written in Rust.

Overview

This project implements a falling sand simulation using WebGPU for GPU-accelerated rendering and computation. The simulation allows particles to interact with each without race conditions by using block cellular automata technique (wiki).

Features

• Real-time particle simulation
• GPU-accelerated rendering using WebGPU
• Interactive simulation controls
• Block cellular automata technique

Getting Started

Prerequisites

• Rust (latest stable version)
• WebGPU-compatible browser or environment

Building and Running

cargo run

This will start the simulation application.

Project Structure

• src/main.rs - Main application entry point
• src/shader.wgsl - WebGPU shaders for rendering
• src/compute.wgsl - Compute shaders for particle simulation
• src/blit.wgsl - Shader for texture blitting operations

Controls

• Mouse click: Add particles
