A small random generator of city models in Blender via bpy

The code generates a city (lots of resized cubes) such that small buildings "grow" towards the center and the skyscrapers just spawn randomly in the middle

Here are the variables:

• roadlen1 - the length of two main roads. It is also a diameter of a circle

• elevationcoef - growth coefficient of small buildings

• houseconstant - constant to lower/lif all the houses at once

• roadwidth1 - width of the main roads. recommended to use even numbers

Secondary always have one end in a main road

• MINroadlen2
• MAXroadlen2 - minimal and maximal length of secondary roads
• roadwidth2 - width of secondary roads
• roadgap2 - minimum distance between two collinear secondary roads
• roadsection2 - multiplied by roadgap2 is maximum distance from center
• axialroads2 - amount of roads on an axis (roads can overlap, so it is a maximal possible amount)

Tertiary roads always start and end in one halfplane

• MINstartlen3

• MAXstartlen3 - minimum and maximum distance from closest end to the main road

• MINendlen3

• MAXendlen3 - minimum and maximum distance from furthest end to the main road

• roadwidth3

• roadgap3

• roadsection3

• axialroads3 - same as for secondary roads

• roofchance - chance of getting triangle roof on top of house

• divcoef - randomness coefficient of small building

• radius - radius of circle where skyscrapers can spawn

• MINdim

• MAXdim - minimum and maximum dimensions of skyscrapers

• MINheight

• MAXheight - minimum and maximum heights of skyscrapers. multiplied by two in the code (ie MAXheight=10 will spawn building with height up to 20)

• MINvert

• MAXvert - minimum and maximum amount of vertices of skyscrapers

• amount - amont of skyscrapers to be spawned (note that two shyskrapers can spawn in one place and look like one)
