Block Round vs Mcgic 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.

Mcgic Circle Generator creates Minecraft circles, ellipses and sphere slices, with real-time 2D and 3D previews. It runs in a browser and supports shapes from 1 to 512 blocks wide, with block counts, coordinates and a layer-by-layer guide. Builder Mode can guide block placement step by step or let users mark blocks directly on the canvas. Designs can be exported as PNG, SVG, JSON with world coordinates, or a .schem file compatible with WorldEdit and MCEdit. The tool has Dark, Light, Forest, Ocean and Classic themes, and saves settings in the browser to restore the last session without an account. On phones, Controls, Preview and Export tabs accompany pinch-to-zoom and touch panning. Mcgic says projects and exports remain on the user’s device rather than being uploaded automatically, though it may use minimal anonymous analytics and third-party integrations. The generator works with full blocks only; slab and stair circle generation is planned for a future update. It is free, requires no login and is available on the web, Android and iOS.
