I found myself enjoyed working on procedural modeling the most back then. So after that semester, I followed a tutorial and learned more about it, and created a building generation tool.  

​

How: 

• The input of the tool is the curve that defines the cross-section of the building. And the output is a building with a set of parameters. 

• So I use the curve as the initial input. Then created floors and walls. Also created UV for each part when building the system. And I created several props in Houdini as randomizable decorations sticky to the wall and roof. 

• And I adjusted the height of the building so that it matches the real human size.
