Open Source Procedural Planet Simulation
Experience real-time planetary generation with dynamic Level-of-Detail rendering, ecosystem simulation, and AI-assisted terrain editing. Free & Open Source for Godot.
About CelestialSim
CelestialSim is a free and open source tool designed for Godot that enables rapid procedural terrain generation and simulation. Built by developers for developers, it leverages dynamic Level-of-Detail (LOD) to ensure smooth, real-time rendering even for complex planetary environments.
What sets CelestialSim apart is its AI-first architecture and open source community. The tool creates embedding-compatible representations of generated worlds, making it seamlessly integrate with AI models for intelligent exploration and content discovery. This opens up exciting possibilities for automated terrain analysis, point-of-interest detection, and AI-assisted world building.
Whether you're developing expansive open-world games or need dynamic terrain for simulation purposes, CelestialSim provides the foundation for creating immersive, procedurally generated environments with cutting-edge performance and AI integration capabilities. Join our growing community of contributors and help shape the future of procedural generation!
