Step-by-step guide

How to use the Sphere Generator

Choose the outside diameter, then select a hollow shell, custom shell thickness or solid sphere.
Select a layer and follow its visual grid or copyable row-by-row column ranges at the matching height.
Repeat every layer in order and use the layer and total counts to verify materials.

Calculation

Formula and game rule

A cell is included when its three-dimensional distance is inside the outer radius. Shell mode also excludes cells inside the radius minus the selected thickness.

Worked example

Example result

For an 11-block sphere, begin at layer 1, keep the same centre point, and advance one vertical block for each displayed layer.

What to check before using the result

Outline mode can use a one-block or thicker shell; Filled mode includes the interior.
The top and bottom layers mirror each other; checking that symmetry catches common building errors.

Java and Bedrock Edition

The generated block layout is edition-independent and works in Java or Bedrock worlds.
