Procedural Generation of Rocky Planets

procedural generation of rocky planets

In this devlog, we explore the new procedural pipeline behind rocky planets in *Essence – Cosmic Engine*.
Each planet is generated from a 5-dimensional signature derived from its physical formation context, including position, mass, stellar distance, and other simulation parameters.

This signature drives a GPU-based pipeline that generates terrain, climate, biomes, clouds, colors, and atmosphere in a coherent way.
The result is a system where planets are not just textured spheres, but evolving worlds whose surface and atmosphere reflect their physical and environmental state.

Building a Believable Universe: Physics, Scale, and Performance in Essence – Cosmic Engine

Essence – Cosmic Engine is built around a physically credible space simulation designed to remain stable, performant, and visually engaging.
This devlog explores how realistic physics, multithreading, intelligent scaling, floating origin, and rendering techniques come together to create a universe that feels vast, coherent, and alive—without sacrificing performance or readability.

Essence – cosmic engine

**Essence – Cosmic Engine** is a revived game project, originally started over ten years ago and now resumed with a clearer vision and renewed experience.
It is a **cosmic sandbox game** that combines physical simulation, god game mechanics, and light management progression, offering players full creative freedom to build and shape their own corner of the universe.

Starting from a single star, players gradually create complex planetary systems governed by consistent physical rules, where balance is the real challenge.
Developed in **Unity** for **PC via Steam**, Essence embraces an open, community-driven development through regular devlogs and an active Discord community.
