Modular procedural terrain generator powered by Rust and WebGPU.

Introduction

Kosmos is a modular procedural terrain generator powered by Rust and WebGPU. It is designed to be a platform for experimenting with procedural generation techniques and rendering algorithms.

Features

Here's a brief overview of the features that are currently implemented or planned:

  • Graph-based interface for creating procedural generation pipelines
  • Real-time rendering of generated terrain using Bevy
  • GPU-accelerated terrain generation using WebGPU and WGSL compute shaders
  • Tile-based and seeded terrain generation for infinite worlds
  • Exporting generated terrain to a heightmap image or a 3D model
  • Support for voxel-based terrain generation for caves and overhangs
  • Easy LOD generation for generated terrain and multi-resolution rendering
  • Support for multiple noise functions, including Perlin, Simplex, and Worley noise
  • Support for multiple terrain modifiers, including nature-inspired procedures like erosion, thermal erosion, and hydraulic erosion

Pipeline Overview

Kosmos uses a graph-based interface for creating procedural generation pipelines, similar to Unreal's graphical scripting and material editor, and existing procedural generation tools like Gaea and World Machine.

The user can create a terrain generator by connecting different procedure together in a graph. Each node performs a specific operation on the terrain, such as generating noise, applying erosion, or applying basic colouring rules.

Internally, each node is implemented as a compute shader, which is executed on the GPU. At runtime, Kosmos compiles the graph into a single compute shader, which is then executed on the GPU to generate the terrain.
