A "seed" is a unique string of numbers that dictates the random generation. Saving a seed allows you to re-generate the exact same layout later or share it with collaborators. Step-by-Step: How to Design a Compelling Fictional City
: While marketed for fantasy, its ability to use custom asset packs allows you to import modern road and building assets to create high-detail modern battle maps.

“Look,” he whispered, pointing. A tiny ambulance was navigating a side street. It took a left, then a right, and arrived at a tiny green square—a clinic—in 47 seconds. “Response time. Half of what we have.”
He typed back: Found it. I’m in the good map. A "seed" is a unique string of numbers
The field is evolving faster than ever, with several exciting trends on the immediate horizon.
He started making a map for himself.

At the cutting edge of research, tools like push the boundaries of what is possible. Developed as a Python package, VoxCity isn't just for generating new cities but for creating detailed 3D voxel models of existing ones by automatically integrating open geospatial data, including building heights, tree canopy, and terrain. This allows for high-fidelity environmental simulations, making it invaluable for academic research into urban heat islands or solar radiation. Similarly, CityGen presents a state-of-the-art framework for infinite, controllable city layout generation, allowing users to guide the process through simple sketches.
