Block Round vs MinecraftCircle Tools

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.

MinecraftCircle Tools is a free web collection for planning Minecraft block geometry. Its circle and oval generator creates symmetrical outline or filled plans with coordinates, layer views, and exports to PNG, Litematic, CSV, TXT, or Markdown; plans can also be shared by URL. Other generators produce hollow or filled spheres, upper-half dome roof plans, and symmetric five-point stars. Sphere views show horizontal slices and layer counts. The sphere and dome interfaces display dimensions up to 129, while the underlying engine and exports support dimensions through 256. Pixel-art images are resized and color-quantized in the browser rather than sent to the server. Circle build progress is kept in browser local storage and, according to the site, is not sent to its server. The site says its grid and row plans describe block positions usable in Java and Bedrock Edition, while Litematic supports compatible Java mod workflows. No account is required. The maker describes the project as independent and not approved by or associated with Mojang or Microsoft. ToolSphere Tech LLC operates the website, whose legal notice provides the tools as-is and as-available.
