Context. Procedural content generation is to algorithmically generate content. This has been used in games and is an important tool to create games with large amounts of content using fewer resources. This may allow small developers to create big worlds, which makes the investigation into this area interesting. Objectives. The Procedural generation of cities using Perlin noise is explored. The goal is to nd out if a procedurally generated city using Perlin noise is viable to use in games. Method. An implementation generating cities using Perlin noise has been created and a user study along with data collection tests the cities' viability in games. Result. The implementation succeeds with all the technical requirements such as performance and determinism. The user study shows that the cities created are perceived as viable in games. Conclusion. The cities generated with the implementation seems to be viable in games. The results show that the generated content are percieved as more viable than random generated cities. Furthermore the generation speed is fast enough to be used in an online setting.

Context: Procedural content generation shortened PCG is a way of letting the computer algorithmically generate data, with little input from programmers. Procedural content generation is a useful tool for developers to create game worlds, content and much more, which can be tedious and time-consuming to do by hand.Objectives: The procedural generation of both a city and height-mapped terrain parameter using Perlin noise and the terrain parameters effect on the city is explored in this thesis. The objective is to find out if a procedurally generated city with a heightmap parameter using Perlin noise is viable for use in games. Methods: An implementation generating both a height-mapped terrain parameter and city using Perlin noise has been created, along with that a user survey to test the generated city and terrain parameters viability in games. Results: This work successfully implemented an application that can generate cities affected with a heightmapped terrain parameter that is viable for use in games. Conclusions: This work concludes that it is possible to generate cities affected with a height-mapped terrain parameter by utilizing the noise algorithm Perlin noise. The generated cities and terrains are both viable and believable for use in games.
