Efficient mesh deformation based on Cartesian background mesh

Robust and Efficient Cartesian Mesh Generation for Component-Based Geometry

This work documents a new method for rapid and robust Cartesian mesh generation for componentbased geometry. The new algorithm adopts a novel strategy which first intersects the components to extract the wetted surface before proceeding with volume mesh generation in a second phase. The intersection scheme is based on a robust geometry engine that uses adaptive precision arithmetic and which au...

Adaptive Cartesian Mesh Generation

The last decade has witnessed a resurgence of interest in Cartesian mesh methods for CFD. In contrast to body-fitted structured or unstructured methods, Cartesian grids are inherently non-body-fitted; i.e. the volume mesh structure is independent of the surface discretization and topology. This characteristic promotes extensive automation, dramatically eases the burden of surface preparation, a...

Pseudo-Skeleton based ARAP Mesh Deformation

In this work, we present a handle-based direct manipulation paradigm that builds upon a pseudo-skeleton with bones that are allowed to stretch and twist. Solving for the unknown positions of the joints in an as-rigidas-possible manner decouples the optimization problem from the geometric complexity of the input model allowing for real-time edits even for high-quality datasets. The degrees of fr...

Nonrigid Medical Image Registration Based on Mesh Deformation Constraints

Regularizing the deformation field is an important aspect in nonrigid medical image registration. By covering the template image with a triangular mesh, this paper proposes a new regularization constraint in terms of connections between mesh vertices. The connection relationship is preserved by the spring analogy method. The method is evaluated by registering cerebral magnetic resonance imaging...
