Block Round vs MC 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.

MC Circle Generator is a free web tool for planning circle and oval block layouts in Minecraft. Choose Hollow, Filled or Border+ mode and dimensions; the grid preview updates as dimensions, modes and display options change. A row guide and pattern panel show block placements from the top of the shape to its center, while the Build Materials panel totals blocks and stacks of 64 and 16. The preview can show X/Y coordinates, and coordinate labels can also be included in exports. Blueprints download as PNG or SVG, with options for grid lines, guides, coordinates, a center marker, title, scale and background. The maker says exported layouts work with Minecraft Java and Bedrock editions, and describes the tool as responsive on PC, tablet and mobile. Ready-made reference sizes run from diameter 3 to 65. The page notes that larger pixelated circles appear rounder, while small ones can show staircase artifacts. It is intended for builders planning features such as chimney caps, arena floors, towers and mega-build foundations. The page states that the tool is not affiliated with Mojang or Microsoft.
