Trimmed Tri-variate Spline Volumes for Design and Simulation in Additive Manufacturing
Trivariate Spline Representations for Computer Aided Design and Additive Manufacturing
Digital representations targeting design and simulation for Additive Manufacturing (AM) are addressed from the perspective of Computer Aided Geometric Design. We discuss the feasibility for multi-material AM for B-rep based CAD, STL, sculptured triangles as well as trimmed and block-structured triva...
A machine learning approach to reverse engineering based on clustering and approximate implicitization
Deconfliction and Surface Generation from Bathymetry Data Using LR B-splines
A set of bathymetry point clouds acquired by different measurement techniques at different times, having different accuracy and varying patterns of points, are approximated by an LR B-spline surface. The aim is to represent the sea bottom with good accuracy and at the same time reduce the data size ...

Comparing Methods for the Approximation of Rainfall Fields in Environmental Applications
Digital environmental data are becoming commonplace and the amount of information they provide is complex to process, due to the size, variety, and dynamic nature of the data captured by sensing devices. The paper discusses an evaluation framework for comparing methods to approximate observed rain d...

Models for Isogeometric Analysis from CAD
In isogeometric analysis splines are used for describing both the geometric shape and the solution fields of the analysis. Although splines are used in boundary structure CAD models, the CAD representation cannot be used directly in isogeometric analysis. We focus on how to build block structured mo...
