This tool now generates a star‑density heat map for an entire sector of Traveller space. A sector is composed of 4 × 4 subsectors; each subsector contains an 8 × 10 hex grid.
If you generate a map you like, make sure to save the "seed" string, which has your current parameters and a random seed.
Within each subsector the densities are created using a simplified slime‑mold algorithm: agents sense the pheromone field ahead, slightly to the left and right, turn towards the strongest stimulus, move forward, deposit trail, and the trail diffuses and decays.
The aggregated field is quantized into discrete colour levels, from black to white. Use the controls below to adjust the number of levels, regenerate the pattern and download it as a PNG.
