|
|
|
|
## Scene Characterisation
|
|
|
|
| Property | Value |
|
|
|----------|-------|
|
|
| Environment | Space |
|
|
| Domain | SPACE |
|
|
| Setting | Low Earth orbit, ~29,400 km altitude |
|
|
| Time of Day | N/A (sunlit hemisphere) |
|
|
| Weather | Cloud systems visible (Antarctic ice cap, cyclone patterns) |
|
|
| Mood | Awe, overview effect, fragility |
|
|
|
|
## Key Elements
|
|
1. **Earth** — full disk, sunlit, Africa and Arabian Peninsula facing camera
|
|
2. **Cloud systems** — swirling cyclones, Antarctic ice sheet, equatorial clouds
|
|
3. **Oceans** — deep blue, Indian Ocean dominant
|
|
4. **Continents** — Africa (Sahara tan, sub-Saharan green), Madagascar, Arabian Peninsula
|
|
5. **Antarctica** — bright white ice cap at bottom
|
|
6. **Black space** — pure black background, no stars (exposure for sunlit Earth)
|
|
7. **Atmospheric limb** — thin blue haze at Earth's edge
|
|
|
|
## Brain Config
|
|
```bash
|
|
python -m brain \
|
|
--reference benchmark/references/space/blue-marble/nasa-apollo17-blue-marble.png \
|
|
--domain SPACE \
|
|
--llm claude --tier opus \
|
|
--max-iterations 20
|
|
```
|
|
|
|
## What Success Looks Like
|
|
- Full Earth disk against black background
|
|
- Correct continent shapes and colours (Africa centred)
|
|
- Realistic cloud patterns with depth
|
|
- Thin atmospheric haze at limb
|
|
- Correct blue ocean colour gradient
|
