Pixel-Perfect Earth Terrain for Minecraft

Generate pixel-perfect worlds from real elevation data, with dynamic tile loading and customizable terrain shaping.

• World type is terrarium:terrarium for servers, singleplayer, select earth when creating world and choose customize to change settings per world.

• Source: AWS S3 (elevation-tiles-prod/terrarium/{zoom}/{x}/{y}.png)
• Temperature and Precipitation Personal Source Hosted on GitHub, I compiled this using QGIS. (clim-monthly/{month}/{zoom}/{x}/{y}) This is a temporary hosting solution
• Pixel-to-Block: 1 pixel = 1 Minecraft block.
• Tile System:
  • Each tile = 256×256 pixels (256×256 blocks ingame).
  • zoom level determines tile count per axis (2^zoom tiles).
    • Example: zoom: 8 = 2⁸ = 256 tiles → 256×256 = 65,536 blocks wide.

• You can download indev test versions here
• Support is not guarunteed for those, only alphas, betas, and releases
• FabricAPI is required

• Scale Examples:
  • zoom: 10 = 1,024 tiles → 262,144×262,144 blocks.
  • zoom: 13 = 8,192 tiles → 2,097,152×2,097,152 blocks.

• Higher zoom = larger worlds but slower generation.
• Reduce zoom to 8–10 for survival-friendly sizes.

• zoom: 10 (small - ~1:48) vs. zoom: 13 (planetary-scale - ~1:6).

• Taken with v0.0.2-beta.2 + Bliss/Photon + WWOO

Zoom: 13 | Height 768

• Tile Fetching: Downloads 256×256 PNG tiles from AWS based on zoom and caches.
• Height Mapping: Converts RGB pixels to block heights, scaled by additionalAlt.
• Biome Placement: Vanilla biomes mapped using elevation (startingY + altitudeDropoff).
