The record

Purpose: Tectonicus generates a 3D model of a Minecraft Java world and uses it to create detailed, zoomable maps.
Map appearance: The project describes its focus as maps that look very close to what players see in Minecraft.
How to run: The README instructs users to download a release, create an XML configuration file, and run Tectonicus from the command line with Java.
Incremental rendering: After the first run, subsequent runs with the same options are significantly quicker because only changed tiles are rendered.
Storage requirements: Generated images can use gigabytes of disk space depending on world size; the README says WebP or JPG and closestZoomSize can reduce this.
Sign filtering: By default, Tectonicus displays every sign players place, and a special filter can restrict which signs appear.
First-person views: Signs marked with #view can create first-person views in the map, with configurable height, angle, field of view, and nighttime rendering.
Minecraft compatibility: The 2.31 release states compatibility with Minecraft 1.21 through 1.21.11 and says Minecraft 26.1 is not yet supported.
Architecture support: Release 2.31 adds arm64 LWJGL natives for M-series Macs and possibly other ARM platforms.
Map subsets: Release 2.31 adds rectangular world subsets alongside circular subsets.
Web map behavior: Release 2.30 says chest inventory tooltips work when the map is served from a web server or when browser CORS is disabled.
License: The repository provides Tectonicus under the BSD 3-Clause license.
Maker: The repository copyright notice names John Campbell and Tectonicus contributors.
Map views: It can generate first-person views from sign locations and insert them into the map, with configurable height, angle, field of view, and nighttime rendering.
