Orthodox Church 3D Modeling with GPT-6 Astra and V2Fun

Overview

The Golden Cupola case develops an Orthodox church exterior using a combination of AI generation and procedural architecture. The prompt requests a church model against a gray gradient background. The supplied presentation adds the architectural direction: pale masonry, dark roofs, arched windows, gold onion domes, and crosses.

The central modeling decision is specific: generate a new central cupola with V2Fun and assemble it with an existing Three.js church. The technical notes describe GPT-6 Astra handling structural understanding and task decomposition. This division of responsibilities follows the broader GPT-6 Astra and V2Fun 3D agent workflow. No case-specific token savings or generation times are supplied.

Tools Used

• GPT-6 Astra: structural understanding and task planning, as described in the technical notes.
• V2Fun: generated modeling references and the central golden cupola mesh, as identified in the presentation.
• Three.js and procedural code: the church architecture and retained accessories identified in the exploded view.
• GLB: the supplied final asset format.

Step 1 — Establish the Modeling References

The input board pairs the original church reference with an isolated golden cupola and supporting church views. The isolated reference makes the cupola’s rounded silhouette, tapered neck, diamond-patterned surface, and base rim easier to inspect.

The supporting side and rear views are labeled as AI-inferred. They provide design guidance without establishing the unseen architecture as observed fact. The single-image and multi-view input guide provides related guidance on preparing references and handling hidden surfaces.

Step 2 — Separate the Architectural Components

The exploded presentation identifies seven groups:

• Golden cupola: the V2Fun-generated central dome.
• Orthodox cross: the retained cross and orb fitted to the new cupola.
• Central drum: a pale stone arcade supporting the dome.
• Four corner towers: smaller domes, drums, and crosses retained in the assembly.
• Church body: procedural masonry, arched facades, and roofs.
• Entrance portal: layered arches, columns, and a reference-derived icon.
• Stone foundation: a stepped plinth, rear apse footing, and entrance stairs.

Only the central cupola is marked as V2Fun-generated 3D. The remaining groups are labeled as procedural Three.js work.

Step 3 — Generate the Central Cupola

The isolated cupola reference is identified as the input used for the new mesh. Its gold finish and diagonal surface pattern distinguish it from the pale drum and darker roofs beneath it. This component is the case’s demonstrated use of the V2Fun AI 3D model generator.

The component board describes PBR textures, but it supplies no texture resolution or material-channel inspection results.

Step 4 — Assemble and Present the Church

The final view shows the new cupola seated above the central windowed drum, with the retained cross at its peak. Smaller golden domes surround the upper church body, while the arched entrance and stairs establish the front of the building.

The presentation states that the delivered GLB was reloaded and rendered as a complete assembly. It describes the result as an exterior study in relative units, with inferred rear architecture and simplified fine ornament.

Workflow

Church reference → Isolated cupola and supporting views → Component decomposition → V2Fun cupola generation → Assembly with procedural Three.js architecture → GLB export and documented reload render.

Prompt

“Display an Orthodox church model against a gray gradient background.”

This is an English translation of the supplied prompt. The final presentation uses a warm neutral background rather than visibly reproducing the requested gray gradient.

Result

The final image presents a complete church exterior with a prominent golden central dome, pale walls, dark ribbed roofs, tall arched windows, and a stepped stone base.
