A Perception Correlated Comparison Method for Dynamic Meshes

A Framework for Dynamic Connectivity Meshes

Implementing algorithms that are based on dynamic triangle meshes often requires updating internal datastructures as soon as the connectivity of the mesh changes. The design of a class hierarchy that is able to deal with such changes is particularly challenging if the system reaches a certain complexity. The paper proposes a software design that enables the users to efficiently implement algori...

Deblocking for Dynamic Triangle Meshes

A Hierarchical Method for Aligning Warped Meshes

Current alignment algorithms for registering range data captured from a 3D scanner assume that the range data depicts identical geometry taken from different views. However, in the presence of scanner calibration errors, the data will be slightly warped. These warps often cause current alignment algorithms to converge slowly, find the wrong alignment, or even diverge. In this paper, we present ...

A High-Order Spectral Difference Method for Fluid-Structure Interaction on Dynamic Deforming Meshes

In previous work by the authors, Spectral Difference Method has been formulated in a framework with time-dependent moving deformable meshes. The framework has also been shown to preserve the design accuracy of the underlying high order temporal (explicit Runge-Kutta) and spatial discretization (Spectral Difference) methods. In this study, Spectral Difference method is further extended to deal w...

Dynamic Adaptive Meshes

In this paper we present dynamic adaptive meshes, a scheme for maintaining a conforming triangulation of time-varying surfaces. The user supplies an initial mesh, a surface sampling procedure and a set of adaptation criteria. The mesh is automatically modified in order to conform to user defined characteristics, while the surface changes over time. Our scheme is very simple to implement. It emp...
