This book presents a new procedural modelling methodology capable of producing traversable buildings constrained by arbitrary convex shapes, based on a pure treemap approach. The authors establish a process to change the format of interior rooms, through wall number modification and offer an adaptation of a fake-concave technique to support non-convex building layouts. It will also include:

• A proposal for an extensible building ontology to guide the methodology process and support the generation of other architectural style buildings (e.g. roman houses);

• A presentation of an ontology-based grammar to provide the procedural modelling methodology with production rules; • Experimental computer managed processes for the stochastic generation of buildings. Most of the existing solutions regarding building interiors only focus on the generation of floor plans mainly composed of rectangular shapes. Yet there are a wide variety of ancient and contemporary buildings that are composed of shapes other than rectangles, both internally and externally. Ontology-based Procedural Modelling of Traversable Buildings Composed by Arbitrary Shapes will address this by providing th e Procedural Modelling field with processes and techniques capable of properly supporting for example, digital preservation of cultural heritage or extensive virtual urban environment productions, specifically ones involving the generation/reconstruction of virtual buildings with such geometric requirements.

Presents an iterative construction of a novel procedural modelling methodology capable of producing 3D building models composed of arbitrary shapes Includes a wide set of figures depicting results to inform the reader about the methodology capabilities in each development stage Demonstrates the software prototype implemented to evaluate both the effectiveness and performance of the new methodology Includes supplementary material: sn.pub/extras

Résumé
"This monograph describes a method for generating models of virtual buildings based on an approach that combines a virtual building ontology with procedural modeling techniques. ... This is a competent contribution to the incremental advance of approaches and techniques in generating building models, and should be an interesting direction for future refinements, useful both for archaeological reconstruction and visualization as well as addressing problems in the generation of virtual environments."
