Procedural modelling is an ongoing field of research\nwhich aims to alleviate this pressure by automatically generating multiple differing variations of models at multiple levels of detail. Within the realm of procedural model\ngeneration, there are a number of techniques specializing in either modelling plants e.g.\nL-Systems or in modelling buildings e.g. shape grammars or other such specialization.\nThe following paper aims to show a possibility of improving this situation, by describing\nthe conception and implementation of a graph grammar and support software, suitable\nfor procedural modelling of both artificial (e.g. buildings and furniture) and organic (e.g.\ntrees and flowers) objects in 2D space. A graph grammar with such aims was previously\nintroduced by Christiansen and Bærentzen [CB13], but with a different definition and\ndifferent characteristics. This work aims specifically to make using the introduced graph\ngrammar simple and improve intuitiveness.

Methods for the synthesis of landscapes, street networks, buildings,\nand vegetation have been described. In the context of the city generation, CityEngine\ncombines some such techniques into a commercial solution that can be used to generate\nthe whole city at once.\nIn the context of park synthesis, the process is divided into layout generation and placement\nof objects in it. Typically, a park layout is either created manually and inserted into\nthe reserved area, or a shape grammar designed for building synthesis is employed. In the\nfirst case, a change to the design or the surrounding regions could result in considerable\nmodifications required of the user. At the present moment, generation of parks and green\nspaces in a city is rather limited and mainly focused on vegetation placement.\nThe aim of our work was to design a method for park layout synthesis, which when\ncombined with basic placement methods could be used to create believable park models.\nBased on the observation of real-life parks and 3D models of parks, we have derived a\nnumber of patterns, which have been translated into the rules of our novel shape grammar.\nIn particular, we introduce a rule for creating curved regions, which, to our knowledge,\nhas not been addressed yet at this level in grammar-based methods.

In this paper we propose a novel approach for the design of architectural floorplans by integrating structural layout analysis directly into the planning process. In order to achieve this, we introduce a planning tool which interactively enforces checks for structural stability of the current design, and which on demand proposes how to stabilize it if necessary. Technically, our solution contains an interactive architectural modeling framework as well as a constrained optimization module where both are based on respective architectural rules. Using our tool, an architect can predict already in a very early planning stage which designs are structurally sound such that later changes due to stability reasons can be prevented.

It was introduced a few years ago and is widely in use, however, its major drawback is the complexity and amount of code that has to be written to create good-looking results. To overcome this problem, a visual editor for the design of buildings is introduced in this thesis. It allows the user to define the aspects of a building in a top-down manner, including their interiors. Starting from the amount of floors, the user is able to define how rooms should be distributed including cross-floor relations, like staircases or elevators. Using 'generation-rules' the user is also able to add more details to the interior (e.g., furniture) and exterior (e.g. facades, plants, etc.).

Common procedural approaches, such as shape grammars, assume that building façades are organized in a tree structure, while in practice this is often not the case. Consequently, the complexity of their layout description becomes unmanageable for interactive editing. In contrast, we obtain a façade by composing multiple overlapping layers, where each layer contains a single rectilinear grid of façade elements described by two simple generator patterns. This way, the design process becomes more intuitive and the editing effort for complex layouts is significantly reduced. To achieve this, we present a method for the automated merging of different layers in the form of a mixed discrete and continuous optimization problem. Finally, we provide several modeling examples and a comparison to shape grammars in order to highlight the advantages of our method when designing realistic building façades.
