Giza V2.1 is a watertight “digital bas-relief” of the Khufu plateau, built as a procedural heightfield on a polar disc and extruded into a closed manifold (χ=2). It includes the Great Pyramid, Queen pyramids, Sphinx with enclosure trench, mortuary temple + causeway, boat pits, temenos wall, and surrounding desert/bedrock. The Great Pyramid uses a true square plan (Chebyshev metric) with linear height falloff, Petrie-slope calibration (~51.844°), and subtle 8-face concavity via a cos(4θ) term. Masonry is expressed as stepped courses (35 visible bands) plus a casing-to-core transition (smooth lower “Tura” vs rough “Mokattam”). Micro-engraved cues mark the north entrance and internal axis (Grand Gallery / King’s Chamber hint). Geology is enriched by PAPP/Hopf-derived stone grain, fault harmonics, and erosion weighting stronger at lower elevations. Mesh: 72,050 verts / 144,096 faces, per-vertex color + normals.
