Exploring Quadrangulations

First, the input shape is segmented into surface patches. Second, different topologies are enumerated and explored in each patch. This is realized by an efficient subdivision-based quadrangulation algorithm that can exhaustively enumerate all mesh topologies within a patch. To help users navigate the potentially huge collection of variations, we propose tools to preview and arrange the results. Furthermore, the requirement that all patches need to be jointly quadrangulatable is formulated as a linear integer program. Finally, we apply the framework to shape-space exploration, remeshing, and design to underline the importance of topology exploration.

Connectivity Editing for Quad-Dominant Meshes

Each type of irregularity has different advantages and disadvantages in design and construction. Irregular vertices are necessary to maintain sharp features (corners and edges), but they create higher angle deviations in mesh lines in smooth regions (left). Irregular faces lead to smoother mesh lines, but they cannot maintain sharp features (right). The ability to model with a mixture of irregular vertices and faces gives more flexibility to the user, e.g. creating a design with sharp features and smooth mesh lines (middle). We render each model in a style that highlights the sharp features.

Connectivity editing for quadrilateral meshes

ACM Transactions on …, Jan 1, 2011

This can lead to improved results in the design of a glass structure: (a) top: the original mesh with irregular vertices as colored dots, (a) bottom: a stripe pattern applied to the mesh, (b) a rendering of the design as glass construction. In (c) and (d) we show the edited mesh. The glass panels on the roof are generated from the edges in the meshes.
