Use L-Systems to create a procedurally generated city.
My inspiration for this project was Asterix's village, which is a vision I kept for most part of my project until I realizzed technical incapabilities like slow obj loading that made me make a more simplistic version of the village that meets the requirements.
I started by designing a grammar for my houses. I added variations like levels, color of the roof, chimney and subdivision.
This is what different instances of the same iteration look like -

Once I was done with this, I thought about how I want to lay out my city. After several trials, I decided to use a pcurve to define my city shape and surround it with forests. I wanted this to change everytime too, so I now I change the bias of the curves everytime.
Then, I wrote a function that takes in the radius and population to make a "cluster" of houses.
This is how the cluster of houses looks like for different populations.

Finally, I integrated my cluster function into a nested for loop to place clusters in some parts of the land. This is also randomized, but stays within the city bounds.
Here are some instances of the city generation.
