Terrain Studio is a new free and open source world building application for easily creating 3d terrain and worlds. Terrain Studio is built on top of the popular Three.js JavaScript framework and can be run entirely in the browser. You can easily create complex terrain environments and export them out to game engines or DCC tools like Blender as height maps or as full textured mesh objects.
Terrain Studio is described as:
A shader-driven procedural terrain generator and editor built with React + Vite + Three.js (WebGL2).
Height, normals and biome colors are computed on the GPU — there is no baked CPU heightmap driving the live view. The app ships three world modes (switchable from the top bar)
Tile
Fixed terrain board with per-chunk LOD — best for painting, multi-tile layouts and exports
Infinite World
Streamed chunk grid around the camera with FPS walk / plane exploration
Planet
Cube-sphere procedural planet with atmosphere, volumetric clouds and orbit camera
