CANDLESTICK TOWER — 3D CONTEXT & NANO BANANA REFERENCE PACK
7 October 2026 • Courtyard Urbanist • Optional concept 01

FOR NANO BANANA
1. Upload Candlestick-Context-hero-4K.png as the primary image.
2. Paste Nano-Banana-Prompt.txt.
3. For a wider composition, start a separate image with the aerial PNG instead. The overhead PNG is an additional geometry reference; it is a perspective overhead view, not a measured orthographic plan.
4. Compare the generated result against the reference, particularly floor count, tower siting, paired wings and courtyard openings. Image generation may change geometry even when instructed to preserve it.

All three PNGs are direct 3840 × 2160 renders of the authored 3D geometry, without interface overlays or a pointer. The earlier atmospheric concept illustration is not the geometry reference for this pack.

INTERACTIVE MODEL
Download and open Candlestick-Tower-Context-Model.html in a modern WebGL2 browser. It is self-contained. Drag to orbit; scroll/pinch to zoom. The selector provides three reference cameras. Download 4K PNG exports the selected reference camera without controls. Show tower concept compares the option with the original neighboring envelopes. Drive previews may not execute HTML: download it first.

3D FILE
Candlestick-Tower-and-Neighborhood.glb contains the tower and the visible authored neighborhood, public surfaces and schematic trees. It uses metres, Y up, X east and Z negative north, with origin centered on the tower. The GLB is for a compatible 3D application and reframing, not a claimed Nano Banana upload format. The NOAA aerial image is omitted from the GLB; it is included in the HTML and PNG context renders. Materials are schematic, untextured PBR colors; original lighting and browser shadows are not baked into this file.

GEOMETRY / PROVENANCE
Neighborhood: CND-2026-10-05-FG3D-FINAL.
Canonical source SHA-256: a26e51d7bf81375092c3f669eaddc5c481d88c24403f0d5e2ef27e797a5e3cde
Source scene copied unchanged; camera and render precision refined for these exports. No new approved neighborhood release or revised program totals.
Tower: CANDLESTICK-TOWER-CONCEPT-01. Trial position at north edge of civic piazza; replaces optional concept envelopes F060_FG3_003 and F060_FG3_004 in this visible variant. Tower-local center in model coordinates: east 727.5 m, north 676.0 m. EPSG:26910 center: 554208.489002403, 4174311.636768735.
26 occupied levels; 276.5 ft main roof; 32 ft lantern; 308.5 ft overall; 110 × 80 ft main footprint. Typical gross plate approximately 6,946.5 sq ft. Core reservation 30 × 64 ft. Dimensions describe the concept, not a fitted or engineered building. Use, apartments, courtyard-facing kitchens, egress, structure and regulatory fit remain unresolved.

SITE CONTEXT / CREDIT
NOAA NGS 2025 San Francisco Bay imagery: https://www.fisheries.noaa.gov/inport/item/75476
Displayed on an approximately registered flat plane, not surveyed terrain. Source imagery EPSG:6339 and model EPSG:26910 use different NAD83 realizations; metre-level registration is not claimed. The proposal is an authored design scenario, not existing buildings or an approved development.

CAMERAS (metres; X east / Y up / Z negative north)
Hero: position [894,137,-440], target [728,35,-638], vertical FOV 40°.
Aerial: position [1175,438,-210], target [775,12,-705], vertical FOV 46°.
Overhead: position [728,640,-675.9], target [728,0,-676], vertical FOV 46°.
All exports 16:9. Near clip 5 m; far clip 5,000 m improves depth precision for closely layered public surfaces without moving geometry.
