Modelling trees according to desired shapes is important for many applications. Despite numerous methods having been proposed in tree modelling, it is still a non-trivial task and challenging. In this paper, we... Read more »

Spatial selections are a ubiquitous concept in visualization. By localizing particular features, they can be analysed and compared in different views. However, the semantics of such selections often depend on specific parameter... Read more »

We present a novel framework for polyhedral mesh editing with face-based projective maps that preserves planarity by definition. Such meshes are essential in the field of architectural design and rationalization. By using... Read more »

This paper proposes an approach to enhance the regional contrasts in snap-shot style portrait photographs by using pre-modern portrait paintings as aesthetic exemplars. The example portrait painting is selected based on a... Read more »

Shape analysis finds many important applications in shape understanding, matching and retrieval. Among the various shape analysis methods, spectral shape analysis aims to study the spectrum of the Laplace–Beltrami operator of some... Read more »

We present a data-driven method for the real-time synthesis of believable steering behaviours for virtual crowds. The proposed method interlinks the input examples into a structure we call the perception-action graph (PAG)... Read more »

Quad layouting, i.e. the partitioning of a surface into a coarse network of quadrilateral patches, is a fundamental step in application scenarios ranging from animation and simulation to reverse engineering and meshing.... Read more »

An important part of network analysis is understanding community structures like topological clusters and attribute-based groups. Standard approaches for showing communities using colour, shape, rectangular bounding boxes, convex hulls or force-directed layout... Read more »

Topological and geometrical methods constitute common tools for the analysis of high-dimensional scientific data sets. Geometrical methods such as projection algorithms focus on preserving distances in the data set. Topological methods such... Read more »
