Polygonal surface processing and mesh generation tools for the numerical simulation of the cardiac function. [PDF]
Int J Numer Method Biomed Eng, 2021 In order to simulate the cardiac function for a patient‐specific geometry, the generation of the computational mesh is crucially important. In practice, the input is typically a set of unprocessed polygonal surfaces coming either from a template geometry

Automating image-based mesh generation and manipulation tasks in cardiac modeling workflows using Meshtool [PDF]
SoftwareX, 2020 Advanced cardiac modeling studies rely on the ability to generate and functionalize personalized in silico models from tomographic multi-label image stacks. Eventually, this is used for building virtual cohorts that capture the variability in size, shape,

Incremental Visual-Inertial 3D Mesh Generation with Structural Regularities [PDF]
IEEE International Conference on Robotics and Automation, 2019 Visual-Inertial Odometry (VIO) algorithms typically rely on a point cloud representation of the scene that does not model the topology of the environment. A 3D mesh instead offers a richer, yet lightweight, model.

Linear Complexity Hexahedral Mesh Generation [PDF]
Proceedings of the twelfth annual symposium on Computational geometry - SCG '96, 1998 We show that any polyhedron forming a topological ball with an even number of quadrilateral sides can be partitioned into O(n) topological cubes, meeting face to face.

Anisotropic Delaunay Mesh Generation [PDF]
SIAM Journal on Computing, 2015 Anisotropic meshes are triangulations of a given domain in the plane or in higher dimensions, with elements elongated along prescribed directions. Anisotropic triangulations are known to be well suited for interpolation of functions or solving PDEs ...

Hexahedral mesh generation via constrained quadrilateralization. [PDF]
PLoS ONE, 2017 Decomposing a volume into high-quality hexahedral cells is a challenging task in finite element simulations and computer graphics. Inspired by the use of a spatial twist continuum and frame field in previous hexahedral mesh generation methods, we present

Unstructured Mesh Generation and Adaptation [PDF]
, 2017 We first describe the well established unstructured mesh generation methods as involved in the computational pipeline, from geometry definition to surface and volume mesh generation. These components are always a preliminary and required step to any numerical computations.
