3D Minecraft layer blueprint
Minecraft Sphere Generator & Layer Blueprint
Enter an occupied outside diameter from 1 to 128 blocks and generate a solid sphere or one-block hollow shell. Review the Y layers from bottom to top, counts, a current-layer PNG, and a full TXT reference for manual building in your browser.
Plan a voxel sphere one layer at a time
Turn one outside diameter into a bottom-to-top 3D voxel sphere plan. Generate a solid sphere or a one-block hollow shell in this browser, then use its layers as a manual build reference.
A dedicated browser Worker generates the sphere locally. Nothing is uploaded, saved to an account, or added to a share link.
Completed-layer marks stay only in this browser memory and are cleared when you refresh.

Build from the bottom layer upward. The grid and exports come from the same voxel mask.
Generate a result before building, then move through its Y layers from bottom to top. Changing the diameter or mode makes the visible result read-only until the inputs match again or a new result finishes.

Build from a fixed voxel plan
Generate a result before building, then move through its Y layers from bottom to top. Changing the diameter or mode makes the visible result read-only until the inputs match again or a new result finishes.
Completed-layer marks stay only in this browser memory and are cleared when you refresh.
PNG downloads contain the current X/Z layer and TXT contains every Y layer. They are manual references, not interactive 3D models, schematics, litematics, or Minecraft worlds.
Minecraft Sphere Generator FAQ
What does the sphere diameter mean?
Diameter is the final occupied outside width in blocks, from 1 to 128. It is the only size input; this page does not use a radius.
What is the difference between solid and hollow?
Solid occupies the full voxel sphere. Hollow removes the matching inner sphere to leave a one-block-thick shell; for diameters 1 and 2 there is no inner space to remove.
How do layers and build progress work?
The plan starts at the bottom Y layer and moves upward. You can mark finished layers only in current browser memory, so progress is not saved after a refresh.
What do the PNG and TXT downloads contain?
PNG contains only the current X/Z layer, while TXT lists every Y layer. Both are manual build references, not a 3D model, schematic, litematic, or Minecraft world.
