Block Round vs Minecraft Circle Generator

Block Round is a free browser tool for making circles, ellipses, spheres, and ellipsoids with Minecraft block textures. Its 2D modes offer Euclidean, Bresenham, and Threshold algorithms; the 3D modes include X, Y, and 45-degree diagonal cuts, with a 3D preview. Users can choose blocks such as Grass Block, Dirt, Stone, Oak, Diamond, Sand, and Gravel, or a Random mix. The tool exports 2D figures as PNG and 3D figures as Sponge schematic v2 files, which WorldEdit, Litematica, and MCEdit can import. It runs in a browser without installation, an account, or a backend, and works offline as a PWA. Settings last for the session and reset to defaults after a reload. A technical math companion is available in nine languages, with each PDF described as at least 25 pages. The project states that its code, layout, design system, and sound engine are All Rights Reserved, and says it is not affiliated with, endorsed by, or sponsored by Mojang Studios or Microsoft.

Minecraft Circle Generator is a free web tool that turns circle dimensions into a block-by-block chart for Minecraft planning. Users set the circle diameter and the inward width of its ring, then receive a grid preview showing placed blocks as green cells. The chart can be zoomed in, zoomed out, or fitted to the view, and the generator reports how many blocks the circle requires. Its supported shape is a circle, with suggested uses including towers, domes, arenas, wells, walls, paths, and decorative rings. The tool runs in a browser without installation and is described as working in modern mobile browsers on phones and tablets. The Free plan costs 0.00 USD and requires no registration. Generated blueprints are planning aids, so users must check whether a layout fits their build.
