Three Novel Algorithms for Triangle Mesh Processing: Progressive Delaunay Refinement Mesh Generation, Mls-Based Scattered Data Interpolation and Constrained Centroid Voronoi-Based Quadrangulation
… I address in the thesis is the conversion of triangle meshes to quadrilateral meshes. Although triangle meshes are preferred in most of applications, quadrilateral meshes show more stability in scientific computation. Because most of acquisition and mesh generation methods result in triangle …

A Framework for Solving Parabolic Partial Differential Equations on Discrete Domains
… of parabolic partial differential equations on triangle mesh surfaces, including the Hamilton-Jacobi equation and the Fokker- Planck equation. Certain PDE in this class often have nonlinear or stiff terms that cannot be resolved with standard methods on triangle mesh surfaces. To address this …

Approximating, Editing, and Processing Free -Form Motion
… but powerful rotation-invariant differential mesh representation that can easily accommodate any connected triangle mesh (including non-manifold and non-orientable surfaces). This representation is useful not only for free-form motion processing but also for general geometric mesh editing.

Algorithms for Smooth and Deformable Surfaces in Three Dimensions
… is guaranteed to terminate with a high quality triangle mesh. In our investigation, geometric properties of the skin serve as the foundation of our proofs and insights for the algorithms. The proofs can be extended to the meshing of other low degree surfaces, such as NURBS. The surfaces created …

Structured meshes: composition and remeshing guided by the Curve-Skeleton
… purely technical, of producing highly irregular meshes that are not optimal for subsequent processing. Converting an unstructured mesh into a more regular and struc- tured model in an automatic way is a challenging task and still open prob- lem. Since structured meshes are useful in different …

Sampling-based coverage path planning for complex 3D structures
… vessels has led to robust operations that yield triangle mesh models of these structures; these models form the basis for planning inspections at close range. We give results from a coverage plan executed at the stern of a US Coast Guard Cutter, and results are also presented from an indoor …

An Approach to 3D Building Model Reconstruction from Airborne Laser Scanner Data Using Parameter Space Analysis and Fusion of Primitives
… building is analysed separately. A 2.5D-Delaunay triangle mesh structure (TIN) is calculated into the laser scanner point cloud. For each triangle the orientation parameters in space (orientation, slope and perpendicular distance to the barycentre of the laser scanner point cloud) are determined …
