Block Round vs Pixel 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.

Pixel Circle Generator is a free web tool for making Minecraft circles, ellipses, arcs, and spheres. Shapes can be outlined or filled, with configurable outline thickness. Dimensions use radius or diameter controls; ellipses add an Ry setting, and arcs accept start and end angles. Sphere previews show one layer at a time from −R through +R, with an option to copy commands for every layer. Generated designs can be downloaded as PNG or SVG, copied as grid text, or converted to /setblock commands for one layer or all sphere layers. Preview controls adjust pixel size, block color, grid, and axes. The tool provides coordinate output and layer-by-layer viewing, but no 3D preview. It runs in a browser and has a free plan priced at free. The site states that it is not affiliated with Mojang or Microsoft.
