THIRD VISION LTD. — ADVANCED MULTI-NODE 360° / VR CONTENT PROMPT & PRODUCTION GUIDE
Version 6.6

GOAL
Create a connected virtual walkthrough of ONE real or concept project, not a collection of unrelated panoramas. Every panorama must represent a deliberate camera position on the same floor plan so the website can show hotspots, route navigation and a live “You are here” marker.

MASTER VISUAL PROMPT
Create a photorealistic 360° equirectangular interior panorama for a premium Third Vision Ltd. architectural/interior walkthrough. Maintain EXACTLY the same architecture, room dimensions, ceiling design, cabinetry, furniture, finishes, lighting fixtures, material colors, windows, doors, decorative objects and time-of-day as the reference project. The new panorama must only change the CAMERA POSITION, as if a person walked to the next marked point on the same floor plan. Do not redesign, add or remove furniture, doors, walls, appliances or decorative elements between nodes. Preserve scale and spatial continuity. Camera height 1.55 m above finished floor, level horizon, zero roll, natural eye-level perspective. Output a seamless 2:1 equirectangular panorama, full 360° horizontal and 180° vertical coverage, with clean poles, no seam, no text, no watermark, no labels, no people, no duplicated objects and no impossible geometry.

RECOMMENDED OUTPUT
- Aspect ratio: exactly 2:1
- Preferred: 8192 × 4096 px
- Good web source: 6000 × 3000 or 4096 × 2048 px
- Minimum trial: 2048 × 1024 px
- Format: JPG/WebP for web, PNG/TIFF master if needed
- Color: sRGB
- Camera height: 1.50–1.60 m, keep identical between nodes
- Horizon: perfectly level
- Exposure/white balance: identical between nodes

NODE PLANNING
Create 3–8 camera nodes per project. Place nodes at natural standing positions, usually 1.5–3.0 m apart, with visible line-of-sight between adjacent nodes.

Example kitchen tour:
01 ENTRY — doorway/entrance position, looking into kitchen.
02 WORK ZONE — central position near island/main counter.
03 DINING TRANSITION — connection between kitchen and dining.
04 PANTRY — optional detailed storage position.
05 LIVING TRANSITION — optional connection to living space.

CONSISTENCY LOCK
For all nodes, explicitly repeat:
“Same exact project. Same geometry. Same cabinet dimensions. Same appliances. Same materials. Same lighting. Same furniture. Same styling. Same day/time. Change camera position only.”

FLOOR PLAN / MINI-MAP REQUIREMENTS
Create a clean top-view floor plan or rendered top view of the SAME project. Mark each panorama camera node by ID (01, 02, 03...). Record each marker as X/Y percentage coordinates relative to the map image.
Example:
01 Entry: x 49%, y 69%
02 Work Zone: x 49%, y 47%
03 Dining Transition: x 23%, y 58%

For each node also record:
- node ID
- display name
- panorama filename
- initial yaw/heading
- adjacent node IDs
- hotspot yaw/pitch directions
- map X/Y percentage

WEBSITE MANIFEST EXAMPLE
[
  {
    "id":"entry",
    "name":"01 / Entry",
    "file":"entry.webp",
    "map":{"x":49,"y":69},
    "startYaw":0,
    "links":[{"to":"work-zone","yaw":18,"pitch":-6}]
  }
]

LUMION / ENSCAPE WORKFLOW
1. Finalize the model first.
2. Put camera nodes on the floor plan before exporting.
3. Keep eye height constant.
4. Export 360 panorama from each node with the same lighting preset.
5. Never change materials or decoration between node exports.
6. Name files by node: 01-entry, 02-work-zone, 03-dining-transition.
7. Export a top-view layout and provide node positions.
8. Test every node in the website viewer before publishing.

VR / WEBXR NOTES
- Website VR requires HTTPS and a WebXR-compatible browser/headset.
- Desktop/mobile users still receive drag, touch, zoom, fullscreen and optional device-motion viewing.
- WebXR mode should be treated as an enhancement, not the only navigation method.
- For headset use, keep high-resolution source panoramas but create optimized web derivatives to avoid long loading times.

QUALITY CHECK BEFORE PUBLISHING
- exact 2:1 ratio
- no visible seam at left/right join
- no broken ceiling/floor poles
- no duplicated cabinets, lights or furniture
- same project geometry at every node
- adjacent nodes make spatial sense
- floor-plan marker matches actual camera position
- hotspot direction points toward the intended next node
- labels clearly indicate DEMO/STUDY if AI-generated rather than a verified Third Vision project

THIRD VISION CONTENT RULE
Never present an AI-generated tour as a measured, captured or completed Third Vision project. For AI/sample tours use “Demo / Replaceable Sample”. For real project tours use verified Lumion/Enscape/captured 360 source files from that project.
