Minecraft Dome Generator
Generate a hollow or filled dome and build it one layer, row and segment at a time.
Build a Minecraft dome without losing your layer
VoxelCurve represents a dome as an upper ellipsoid. Each horizontal layer is broken into rows and exact block segments, so the same blueprint can guide both small roofs and large survival builds.
Hemisphere, low dome or tall dome
Width and depth define the footprint. Height controls the profile. Use the hemisphere shortcut for a classic half-sphere, reduce height for a flatter roof, or increase it for a taller elliptical dome.
Hollow domes are true shells
The hollow mode subtracts an inner ellipsoid from the outer structure instead of simply drawing a thin circle on every layer. That keeps the cap and upper layers structurally consistent.
Layer navigation
The guided builder tracks the current layer, row and segment. Complete a segment and VoxelCurve moves to the next instruction while keeping progress in your current browser.
Useful starting dimensions
These hemisphere-style presets use a one-block hollow shell. Open one directly, then adjust the dimensions if needed.
