Fantasy Map Generator
I made this to quickly test fantasy map shapes, seeds, coastlines, islands, and terrain styles without opening a full map editor. It is still a work in progress, so I am adding and tuning features as I go.

About the Fantasy Map Generator
The GameBeyond Fantasy Map Generator was built to explore how believable fantasy geography can emerge from a small set of repeatable rules. Instead of drawing a fixed map by hand, the generator treats the world as a system: points, regions, elevation, coastline pressure, and shading all combine to create a map that feels discovered rather than placed.
How it works
Each map starts with thousands of evenly distributed points. Those points become a Delaunay and Voronoi-style mesh, giving the terrain natural polygonal regions instead of a rigid square grid. Seeded noise then assigns elevation across the mesh, while island shaping, sea level, coast noise, and hill height controls adjust how the land gathers, breaks apart, rises, and sinks.
Why it was made
The goal is to make map generation feel controllable without turning it into a complicated editor. A seed gives every world a stable identity, while the sliders reshape the same underlying world logic in real time. This makes it easier to study how procedural geography behaves: how a continent becomes an island chain, how coastlines become rougher, and how elevation changes the visual character of a world.
Features
- Instant procedural generation that runs entirely in your browser.
- Seed-based reproduction so the same world can be regenerated anytime.
- Real-time controls for island shape, sea level, coastline noise, hill height, and camera angle.
- Multiple render materials, including colored terrain, grayscale, height map, and wireframe views.
- PNG download for saving the current generated map.
- Natural coastlines, mountains, and ocean depths rendered in a parchment-inspired palette.
This tool is a work in progress. Biome classification, rivers, interactive painting, and deeper map style controls are being built.
