Visigenesis - World-Engine

Visigenesis is a 3D world editor that runs entirely in your browser. No install, no account, no cloud. Unzip, double-click, and the editor opens on a finished world.

Every world starts from a seed. Roll it and the terrain, rivers, coastline, climate and vegetation change together, because they are all solved from the same source. Erosion runs on a worker while you watch. Change one dial and the whole landscape answers.

Then make it yours:

Sculpt the terrain with brushes that respect the water table and the rivers.

Place buildings, props and settlements from a block catalogue, and they seat themselves on the ground.

Build a settlement in one press. Two world grammars ship with it. Farshore puts a fishing village on the grass above a bay with a field study on the height behind it. Lonepalm puts one pink house on a sand island in a lagoon. Each is a rule, not a layout, so every seed draws a different map that still obeys it.

Walk inside. Every landmark has a real interior with rooms, doors and fittings you can walk through at eye level.

Export is one press and it is yours. You get terrain.glb, a 16-bit heightmap, biome and water masks, placements.json, site.json, a manifest, and a Unity folder with an Editor importer and the raw .r16 heightmap. Drop it into Unity and the world is standing there. Everything you export is royalty-free and needs no attribution. Sell it, ship it, build a game on it.

Five worlds are included ready to open: alpine, badlands, tundra, weald and verdant.

You get the source. Visigenesis has no build step. The editor and the engine are plain ES modules that the browser loads directly, and they are in the download, readable and commented. Read how the erosion works. Change the palettes. Add your own block pack. The licence lets you read and modify it for your own use.
