GEOMETOR • etc¶
Digital reconstruction, semantic index, and composable geometric modeling of Clark Kimberling’s *Encyclopedia of Triangle Centers* (X1–X53144).
geometor.etc transforms the archival HTML volumes of Clark Kimberling’s Encyclopedia of Triangle Centers and its supporting Glossary into structured registries, executable geometor.model construction scripts, interactive multi-triangle SVG diagrams, and a 2-track Book Codex edition powered by photon-platform/publish.
Each center features a synchronized Overview track (with .. enunciation::, .. signature:: center trilinear/barycentric coordinates, collapsible incidence/relation tables, and interactive SVGs across Acute, Right, Kepler, and Kimberling reference triangles) and a Code track (with standalone model.py constructions).
