Source review
Confirm scope, accuracy, formats, coordinates and intended use.
Capabilities
Production organized around a usable result
Source data, accuracy and intended use define the workflow. These capabilities can be combined without forcing the project into a fixed package.
Reconstruction diagnosis
Review coverage, control points, coordinates, holes, ghosting, floating geometry and texture seams.
Mesh repair and cropping
Remove invalid geometry, improve priority areas and crop results by boundary or spatial hierarchy.
Object indexing
Add building or facility indices for selection, queries, styling and business-data association.
3D Tiles publishing
Tune hierarchy, geometric error, texture resolution and tile boundaries for Cesium streaming.
Delivery Standard
Acceptance criteria before delivery
Specific values depend on the source data and target environment. Applicable criteria are agreed at the start instead of relying on vague quality labels.
| Typical input | Aerial imagery, OSGB and reality meshes |
|---|---|
| Primary output | 3D Tiles and optimized meshes |
| Quality focus | Large scenes and streaming |
| Asset hierarchy | Objects organized by building, floor, system, equipment or component |
| Runtime fit | Optimization for the target browser, desktop or mobile environment |
| Review method | Pilot approval, milestone previews, issue list and final validation |
Workflow
Approve a pilot before batch production
A representative pilot validates source quality, accuracy, visual language, hierarchy and performance early in the project.
Pilot approval
Lock hierarchy, detail, materials and performance on a representative asset.
Batch production
Model, review and preview assets against the agreed manifest.
Final validation
Verify files, versions, hierarchy, performance and delivery notes.
FAQ
Frequently asked questions
Why does a photogrammetry scene load slowly?
Common causes include oversized tiles, weak hierarchy, excessive textures, incorrect geometric error and ineffective server caching.
Can OSGB be converted to 3D Tiles?
Yes, but coordinates, hierarchy, textures, empty nodes and tile boundaries must also be reviewed.
Can individual buildings be selected?
A separate boundary, proxy or index layer is normally required because the original reality mesh is continuous.
Can every hole and texture defect be repaired?
Priority areas can be improved, but missing or heavily occluded source imagery limits what can be reconstructed reliably.
