Procedural modeling approaches in computer graphics

Procedural modeling offers means for computer guided generation of graphical models in high quantity and quality. Since it is a wide field of research it does not have an universal solution but offers many different concepts. This thesis consequently introduces, analyses and implements just the four most common techniques with different concepts. The most universal concept are fractals, which can be used for every model with a certain degree of self-similarity. Strong techniques are also shape grammar and L-system. Shape grammar extends a simple model in steps into a more complex one and it is therefore appropriate for generating architecture. In contrast L-system simulates the model's growth, which makes it most commonly linked to plant models. The last selected concept is the simple but efficient heightmap, which is common in terrain generation but not restricted to that.
