TerraMath
by addavriance
With TerraMath, a server owner or world creator writes a mathematical formula that sets the terrain height across a new world.
What it does
TerraMath replaces the usual terrain shaping with custom terrain generated from mathematical functions. A formula entered in the world creation screen defines the terrain height at each position, which lets a world take shapes that the standard generator does not produce. The Go World tab of the world creation screen opens a terrain settings screen, and the formula goes into a dedicated field there.
Basic generation can be adjusted through scale, height variation and smoothing, and a noise overlay can be configured on top of the base formula. The formula field accepts mathematical constants and functions, so a formula can combine several terms. Only the server needs the mod for the generated terrain to take effect. Mod Menu is an optional dependency that adds a menu entry for the mod's settings.
TerraMath is open source under the GNU General Public License v3.0 only and is published for Fabric and Forge across 12 release versions, 1.20 – 1.21.4. The first file was released on 2024-11-27, and the latest was published on 2025-05-13 for 1.21.4.
Key features
Formula-based terrain
Terrain height is defined by a mathematical formula, so each new world can have its own landscape shape.
Adjustable generation parameters
Scale, height variation and smoothing can be tuned to change how the formula shapes the land.
Configurable noise overlay
A noise layer can be applied over the base formula to add surface detail to the generated terrain.
Terrain settings screen
A settings screen opens from the world creation Go World tab, where the formula field and generation options are set.
