Recent shape retrieval and interactive modeling algorithms enable the re-use of existing models in many applications. However, most of those techniques require a pre-labeled model with some semantic information. We introduce a fully automatic approach to simultaneously segment and detect similarities within an existing 3D architectural model. Our framework(More)
The demand for 3D city-scale models has been significantly increased due to the proliferation of urban planning, city navigation, and virtual reality applications. We present an approach to automatically reconstruct buildings densely spanning a large urban area. Our method takes as input calibrated aerial images and available GIS meta-data. Our(More)
This course presents a collection of state-of-the-art approaches for modeling and editing of 3D models for virtual worlds, simulations, and entertainment, in addition to real-world applications. The first contribution of this course is a coherent review of inverse procedural modeling (IPM) (i.e., proceduralization of provided 3D content). We describe(More)
Figure 1. City-Scale Building Proceduralization. Our approach uses a) an unorganized 3D model as input, b) computes a hierarchical clustering of building components, and c) extracts a context-free grammar of the urban area. We can procedurally generate (d-e) structurally-similar cities, at a chosen de-instancing level c) Grammar Abstract—We present a(More)
