Deployed.https://perplace.com/changelog/#log-2026-09-11-enperplace-changelog-2026-09-11Fri, 11 Sep 2026 12:00:00 GMTLanding embeds the real viewer on a pipeline-produced district, full city loading on demand, 3D gallery of city and floor plan. Whole-building authorship covers every facade, the roof and its tank; arched windows and adaptive shaft composition as orders.https://perplace.com/changelog/#log-2026-09-10-enperplace-changelog-2026-09-10Thu, 10 Sep 2026 12:00:00 GMTAI architect directs a building through explicit orders: facade composition, pilasters, entrance carpentry, cornice, crowning, arches, roof with water tank, relief, regional materials. Procedural tools build each order; an independent visual critique accepts or rejects it.https://perplace.com/changelog/#log-2026-09-09-enperplace-changelog-2026-09-09Wed, 09 Sep 2026 12:00:00 GMTAI visual judge loop: render a building from chosen viewpoints, compare against a typed reference under a derived tolerance, score with a deterministic signal before any model opinion.

Floor plans know their level; cores against blind walls; egress follows the building program; occupants derived from nearby jobs. Street objects declare their scale in the data.https://perplace.com/changelog/#log-2026-09-01-enperplace-changelog-2026-09-01Tue, 01 Sep 2026 12:00:00 GMTOne object per building: the interior references the facade's walls and openings instead of rebuilding them. Interior viewer shows the real facade cut at floor level with its material. Street doors, facade colours and street furniture sourced from observed data.https://perplace.com/changelog/#log-2026-08-31-enperplace-changelog-2026-08-31Mon, 31 Aug 2026 12:00:00 GMTInterior set as the primary objective.

Typed street-to-room path.https://perplace.com/changelog/#log-2026-08-30-enperplace-changelog-2026-08-30Sun, 30 Aug 2026 12:00:00 GMTInterior programs: one specification derives dozens of room programs as a graph. Viewer: enter a floor from the street, ride the elevator, toggle slabs per building, click a module for its typed record. A design request alone rebuilds a building exactly: reproducible worlds.https://perplace.com/changelog/#log-2026-08-29-enperplace-changelog-2026-08-29Sat, 29 Aug 2026 12:00:00 GMTglTF export: every node carries the id of its typed record; mesh to data round trip in the viewer.

Sidewalk overhang as a per-street rule. Facade packs carry profiles, not meshes.https://perplace.com/changelog/#log-2026-08-22-enperplace-changelog-2026-08-22Sat, 22 Aug 2026 12:00:00 GMTAuthor vocabulary: cornice, canopy with overhang, signed depth for facade elements, dedicated roof section. Rules written per face, so street fronts and party walls diverge. Leftover rhythm resolves at the top floor.https://perplace.com/changelog/#log-2026-08-21-enperplace-changelog-2026-08-21Fri, 21 Aug 2026 12:00:00 GMTA building always renders: a rejected facade request degrades by cell or by face and keeps the building. Rejections are typed records with a reason catalogue. Viewer colours each facade module by author: AI architect or procedural engine.https://perplace.com/changelog/#log-2026-08-20-enperplace-changelog-2026-08-20Thu, 20 Aug 2026 12:00:00 GMTStaged authoring cycle: design, elevation, deterministic judge checking each request against built geometry.

Wavy parapet profile from intent to geometry.https://perplace.com/changelog/#log-2026-08-17-enperplace-changelog-2026-08-17Mon, 17 Aug 2026 12:00:00 GMTMasonry facades arch their own openings: arched heads with glazing, built from level courses. Ground floor follows building type: walk-ups get solid bases, shops align to the bays above. Design decisions reviewed in the 3D viewer, not on drawings.https://perplace.com/changelog/#log-2026-08-16-enperplace-changelog-2026-08-16Sun, 16 Aug 2026 12:00:00 GMTContinuous strip opening type: curtain walls and ribbon windows render as real glazing. Partition tree, the structural recipe behind each facade, persisted as its own artifact. Vocabulary covers mansards with dormers, faceted curved fronts, overhanging masses.https://perplace.com/changelog/#log-2026-08-15-enperplace-changelog-2026-08-15Sat, 15 Aug 2026 12:00:00 GMTPer-building facade parameter vector with provenance per axis; viewer paints the city by any axis.

Parapet belongs to the mass. Viewer opens on the full city with a layer panel organised by question. Binary geometry by default.https://perplace.com/changelog/#log-2026-08-13-enperplace-changelog-2026-08-13Thu, 13 Aug 2026 12:00:00 GMTCity streaming by distance: buildings loaded and released, geometry resident on the GPU and dropped from main memory. Compact columnar binary format for building geometry. LOD switch rewrites only the facade face that changes.https://perplace.com/changelog/#log-2026-08-12-enperplace-changelog-2026-08-12Wed, 12 Aug 2026 12:00:00 GMTFull-city facade emission in one run.
