What MinecraftDome is
MinecraftDome is a free, open-source web application that generates dome shapes and construction plans for Minecraft. Users draw connected square-mesh surfaces as circles, rectangles, diamonds, ellipses, or hyperellipses, then place anchors to constrain the surface. Anchors in one layer are treated as points on a plane defined by three points. Generation settings include parabolic load, catenary load, and roof load; setting loads to zero creates a soap-bubble effect. The display can show ideal blocks, a line grid, or Minecraft blocks, with an option requiring neighboring blocks to meet by a face. The app produces fixed-width plain-text plans for copying, pasting, or printing. Plans mark X and Z every 16 blocks and Y every 8 blocks, with offsets for chunk-boundary lines. The documented version has no save, restore, or undo feature. Catenary calculations may run to infinity, so instructions advise keeping reset available. Paul Murray lists email support and optional PayPal donations. The project uses the Creative Commons Attribution 4.0 International license.
Good
- Supports several mesh-based dome shapes
- Anchors constrain generated surfaces
- Displays ideal, grid, or Minecraft blocks
- Produces copyable fixed-width text plans
- Includes chunk-aligned coordinate markings
Watch out
- No save, restore, or undo
- Catenary calculations can run to infinity
- Results may vary by browser and device
- Optional donations are suggested
Who it suits
It suits Minecraft builders planning custom dome structures in a browser. Users should be comfortable working without save, restore, or undo controls.
Verdict
MinecraftDome turns configurable mesh surfaces into visual previews and text construction plans. Its coordinate markings and shape controls support detailed building layouts, but the documented version lacks project recovery controls and can encounter unbounded catenary calculations.
