Astroworld Circle & Dome Generator vs MinecraftMaps Pixel Circle Generator

Astroworld Circle & Dome Generator is a free web tool for planning Minecraft structures with pixel grids. It generates circle outlines, filled circles, domes and sphere shells from whole-block diameters between 1 and 256. The selected shape’s total block count appears before construction. Gold cells indicate blocks to place, while dark cells indicate empty space; large grids are compressed to fit the screen. A layer slider lets you inspect dome and sphere-shell builds one layer at a time. The page says block positions are calculated in your browser from the diameter entered. You can embed the generator in a website or server wiki with an iframe and set its width, height and theme. The free plan costs nothing, with no sign-up and no ads. It is intended for Minecraft builders planning towers, arenas, greenhouses, planetariums and spheres.

MinecraftMaps Pixel Circle Generator is a free web tool for planning Minecraft circles, ovals, and ellipses block by block. A live grid changes with the selected dimensions and style, while the page reports the exact block count and equivalent stacks of 64. Thin creates a one-block outline, thick creates a two-block ring, and filled creates a solid disc. Turning off the force-circle lock allows different widths and heights for oval shapes. The current grid can be downloaded as a PNG reference image, and coordinate output is available. The generator fills blocks whose square centers fall inside the chosen circle or oval; outline modes remove inner blocks. Its guidance recommends building one quadrant from the center and mirroring it across the other three for symmetry. Suggested applications include tower walls, silos, pond rims, floors, ceilings, and platforms. MinecraftMaps.com says it began in November 2011 and is not affiliated with Mojang or Microsoft.
