CartoVoxel Minecraft Shape Maker vs McMeddon's Worlds

CartoVoxel Minecraft Shape Maker is a free web tool for planning block geometry with a live 3D preview and coordinate exports. It provides 11 shapes: sphere, cylinder, cone, pyramid, dome, prism, torus, ogive cone, hyperboloid, star and spiral. Users can adjust dimensions, select a material color preset or Minecraft block ID, and toggle filled geometry. A layer view displays generated coordinates in a grid one Y level at a time. Export options are a browser-readable layer guide, JSON coordinates and shape settings, and a Java mcfunction intended for Minecraft Java Edition creative worlds or datapack workflows. Shape generation, previews and downloads run locally in the browser after the page loads; the page says shapes and settings are not uploaded. The tool does not create Litematic, schem, Bedrock structure, mcworld or complete world files. CartoVoxel describes the service as web-based, with no downloads or heavy software required. The listed plan is free and includes all 11 shapes, live 3D and layer views, and the stated exports.

McMeddon's Worlds is a library of custom Minecraft worlds, with data and a browser-based 3D explorer for surveying terrain before downloading. Visitors can fly over landscapes in the browser without installing software. The collection spans survival, creative, single-biome, civilization, SkyBlock, seasonal, community, and test worlds; multiplayer maps and search filters are available. Downloads are for Java Edition, while Bedrock files are limited to worlds explicitly marked as compatible. The maker describes building terrain with World Machine, adding trees and structures in Minecraft, then assembling and exporting maps with WorldPainter. Some world files are free; others require the indicated Patreon membership. Small survival worlds are listed at $5 a month and large ones at $9 a month. Worlds downloaded during membership remain playable after it ends, but further downloads stop. Browser utilities include a Java vault fixer, a loot chest command generator, and a searchable world contents finder. Bedrock conversions may have rough edges, empty chests, or missing living villagers. Worlds are generally under a license requiring attribution and barring as-is resale or redistribution.
