PlanetGen
Streaming procedural planets and ring worlds with climate biomes, atmospheres, foliage, water and multiplayer gravity.
Highlights
- Spherical planets and ring worlds that stream at runtime, built on a thread pool so the game thread is never blocked
- Climate biomes (Tundra, Boreal, Desert, Tropical) with polar ice caps
- Many planets in one level, with per-planet atmospheres and a correct night side
- Multiplayer gravity character: walk, wade, jetpack and hyperdrive anywhere
- Exclusion volumes and a biome-aware actor spawner for hand-built content
