Investigation Context

Introduction​
This page covers what a splat reconstruction may claim and what it may not: evidentiary considerations, the documentation a methodology section needs, and the limits you must state when the model is presented as evidence.
Evidentiary Considerations​
- Admissibility of 3DGS visualizations in court
- GS as visual aid vs. forensic measurement
- Chain of custody for splat data
Documentation Requirements​
- Following the Berkeley Protocol
- What to document in your methodology section
- What to record in your decision log
- Version tracking for tools and models
When to Use GS vs. Alternatives​
| Scenario | Best Approach |
|---|---|
| Need photorealistic context | GS |
| Need precise measurements | Mesh photogrammetry |
| Need both | GS + mesh combined |
| Single image | Camera matching |
| Video with motion | Camera tracking |
Limitations to Document​
- Hallucination risk in unseen areas
- Scale drift without reference
- Reflection/transparency artifacts
- Computational requirements
Summary​
A splat reconstruction is a visualization with limits, and the limits are the part an investigation must document. You now know what belongs in a methodology section: the tool versions, the capture, the training settings, and the statements a splat model cannot support on its own.
