|
||||
|
||||
### Metrics Comparison: Baseline → Best (v7)
|
||||
|
||||
| Metric | Baseline | v7 | Change |
|
||||
|--------|----------|-----|--------|
|
||||
| relief_headroom | 0.487 | 0.547 | +12% more dramatic |
|
||||
| coast_complexity | 27.9 | 28.5 | +2% more complex |
|
||||
| hypsometry_trough | 0.79 | 0.78 | ~same (good) |
|
||||
| mountain_boundary_ratio | 0.52 | 0.52 | same |
|
||||
| land_500m_plus_frac | 0.26 | 0.31 | slightly more highland |
|
||||
| flat_ocean_plate_land | 0.65 | 0.59 | -9% improved |
|
||||
| island_count | 286 | 288 | same |
|
||||
| erosion_slope_corr | 0.46 | 0.46 | same |
|
||||
| shelf_width_active_km | 293 | 222 | -24% narrower (more realistic) |
|
||||
| shelf_width_passive_km | 478 | 443 | -7% narrower |
|
||||
|
||||
### Visual Improvements (confirmed at 31K and 90K regions)
|
||||
|
||||
1. **Mountain ridges** more defined with visible linear structure
|
||||
2. **Continental interiors** have more elevation variety (craton vs basin contrast)
|
||||
3. **Rift valleys** more visible as distinct features
|
||||
4. **Ocean floor** more differentiated (deeper trenches, visible ridges)
|
||||
5. **Coastlines** slightly more complex
|
||||
6. **Peaks** more prominent and frequent
|
||||
|
||||
## Saved Config Snapshots
|
||||
|
||||
All in `tuning/results/`:
|
||||
- `config-sharper-mountains.js` — fold freq + ridge + dissection only
|
||||
- `config-sharper-mtn-interior-contrast.js` — + interior contrast
|
||||
- `config-combined-v2.js` — + peak compress + less craton suppress
|
||||
- `config-combined-v3-rifts-summits.js` — + rifts + summits
|
||||
- `config-combined-v4-ocean.js` — + deeper trenches/back-arcs
|
||||
- `config-combined-v5-warp.js` — + subtle warp boost
|
||||
- `config-combined-v6-full.js` — + edge preserve + ridge sharpen
|
||||
- `config-combined-v7.js` — + basin suppress + chaotic folds (**BEST**)
|
||||
|
||||
## Key Learnings
|
||||
|
||||
1. **Elevation thresholds must use quartic mapping** — elevToHeightKm is t^4-based, so 500m = elev 0.40, not 0.0625
|
||||
2. **Hypsometric curve blend has minimal effect** — pre-existing distribution dominates
|
||||
3. **Dissection is the #1 lever** for breaking up blobby mountains into realistic ridges
|
||||
4. **Stress decay is delicate** — 0.5 original is right; 0.6 spreads too wide
|
||||
5. **Deeper ocean features improve shelf differentiation** — more room for gradient
|
||||
6. **Volcanic feature boosts backfire** — more arc uplift = more flat land, not taller islands
|
||||
7. **Hotspot increases reduce island count** — merging features into fewer larger masses
|
||||
8. **Interior shield/basin contrast** creates visual variety on continents
|
||||
9. **Edge sensitivity in smoothing** preserves features that other steps create
|
||||
10. **Fold frequency boost** is most visible at low detail levels (default view)
|
||||
|
||||
## Parameters Still Worth Exploring
|
||||
|
||||
- Glacial erosion parameters (only tested at user-slider level, not internal constants)
|
||||
- Coastal plain width and depression (small effect individually)
|
||||
- Island arc geometry (ARC_DIST_BASE, ARC_SIGMA_BASE_VAL)
|
||||
- Super-plate blend weights (SMALL_W, SUPER_W)
|
||||
- Hydraulic erosion deposit fraction and slope sensitivity
