Use Coordinates as a Building Reference
Set the diameter and copy the generated block positions for a sphere or dome. Place the blocks in Minecraft using the coordinates as a reference; this page does not build in-game.

Introduction
What is the Minecraft Sphere Generator?
Use this tool to plan a full Minecraft sphere or an upper-half dome. Choose a diameter from 1 to 64 blocks, then select solid or hollow. Inspect the 3D preview and layers, copy block coordinates, or save a snapshot. Hollow domes have an open bottom.
Benefits
Why Use the Minecraft Sphere Generator?
Preview the shape and layer counts before placing blocks in Minecraft. Sphere and dome modes share the same diameter and solid or hollow controls.
Inspect Odd and Even Diameters
The preview and coordinate list show the generated blocks for both odd and even diameters. Check the layers to see whether the shape fits your build.
Preview Before Placing Blocks
Rotate the 3D preview and use the layer slider to inspect the generated sphere or dome before building. The PNG snapshot saves the current view.
How to Use the Minecraft Sphere Generator
Choose a sphere or upper-half dome, then use the preview and layer slider to plan the build.
1. Set the Diameter (1–64; 0 clears)
Choose Sphere or Dome, then set a build diameter from 1–64. Set 0 to clear the preview and produce no blocks. Dome mode generates only the upper half; a hollow dome remains open at the bottom.
2. Choose Fill and Texture
Choose Solid for a filled shape or Hollow for a shell. Hollow domes remain open at the bottom. The palette button changes the preview texture.
3. View Layers (Optional)
Move the layer slider to reveal the selected sphere or dome from its lowest Y layer upward. The copied coordinates still include all generated blocks.
4. Copy Coordinates or Save an Image
Copy all generated 3D block coordinates or download a snapshot. In Dome mode, the coordinates contain only the upper half.
Key Features of the Minecraft Sphere Generator
The generator provides shape, fill, preview, layer, coordinate-copy, and PNG snapshot controls for block-based spheres and domes.
Build Diameters 1–64
Generate solid or hollow spheres and upper-half domes with diameters from 1 to 64 blocks. Set 0 to clear the preview and produce no blocks.
Solid and Hollow Modes
Solid includes the interior blocks; Hollow keeps the outer shell. A hollow dome has no filled base.
Texture Preview
Switch block textures in the preview. Texture selection does not change the generated coordinates.
Layer Viewer
Move the Y-axis layer slider to reveal the selected sphere or dome from its lowest layer upward.
Copy Block Coordinates
Copy X, Y, and Z coordinates for every generated block in the selected sphere or dome, including layers hidden by the preview slider.
Download a PNG Snapshot
Capture a PNG image of your current block-based view for reference using the minecraft sphere generator.
Fullscreen Preview
Expand the preview to fullscreen if your browser supports fullscreen mode.
Odd and Even Diameters
Odd diameters use a block-centered grid; even diameters use a half-block center offset. Diameter 24 retains its existing outer-layer pattern.

FAQ
Minecraft Sphere Generator FAQs
Answers about sphere and dome shapes, copied coordinates, and the available preview controls.
How does this Minecraft Sphere Generator handle even diameters?
For even diameters, block centers sit half a block away from the geometric center. The preview uses that offset; diameter 24 also keeps its existing outer-layer pattern.
Can I use this tool as a building reference?
You can copy the generated X, Y, Z block positions or download a PNG of the current view as building references. This tool does not export a schematic or WorldEdit command.
How is this different from WorldEdit?
This page previews sphere and dome blocks and lets you copy their coordinates or save a PNG. It does not place blocks in Minecraft or execute WorldEdit commands.
Can I use this to generate domes?
Yes. Select Dome to generate the upper half directly. Choose Solid for a filled base or Hollow for an open bottom, then copy the dome coordinates or download a snapshot.
Is the Minecraft Sphere Generator free?
Yes. The tool is free to use for diameters from 1 to 64 blocks. Diameter 0 produces no blocks.
