New Features ...… in the MeshGems API:• The Mesh statistics are now providing the tetrahedra's height• Cracks inside a mesh can be defined by several ways, including discrete and analytical inputs. ... in Surface Meshing:• Meshing on discrete CAD (MeshGems-CADSurf) now supports preservation of mesh ridges and corners, mesh matching constraints, anisotropic sizemaps on mesh vertices• Capability to use volume and/or surface proximity information to drive automatically the mesh generation (MeshGems-CADSurf): – 2D proximity detection helps to produce quality meshes even though geometry-contrained areas are present on the surface; – 3D proximity detection takes into account the volume thickness information when generating surface meshes, helping to produce better quality volume meshes at the end of the meshing process. • Local anisotropic physical sizemaps on CAD faces are now available (MeshGems-CADSurf). ... in Mesh Processing:• New options to project free bounds to a nearby surface to seal off volumes (MeshGems-Cleaner).... in Volume Meshing:• New option to strictly respect a specified maximal edge length (MeshGems-Tetra).• Optimization with worst quality target theshold (MeshGems-Tetra). • Callback for user-defined quality (MeshGems-Tetra HPC). • Monotonous optional tetrahedron quality callback (MeshGems-Tetra HPC). • Interrupt callback to enhance the control of the execution flow (MeshGems-Hybrid). • Optimization of user-provided input volume meshes when inserted into the volume mesh. The mesh density can be specified just like when starting from a surface mesh (MeshGems-Tetra HPC).

Are you interested in surface meshing from a cloud of 3D points?As part of the MeshGems 2.7 distribution is included a demonstrator of an upcoming product, MG-PointCAD, which automatically builds a surface triangulation from a cloud of points (known by their (x,y,z) coordinates). We invite you to test it on your projects and to send us your feedbacks to help us improving it and making an industry-level product.Based on our famous MG-Tetra tet mesher, this technology for building a surface meshing out of a cloud of 3D points benefits from its assets, which made this technology the worldwide reference technology for tetrahedral meshing. The most significant are its best-in-class industry-level robustness and efficiency, and its speed: typically a few minutes per million vertices.While being an early version, many useful features are already available, like: • the input may contain set of points representing unclosed surfaces, and several connex components; • basic filtering can be achieved: f.e. points which are too close, noisy points, very small artifact components, etc...; • many complementary approaches can be used for best results, like proximity, regularity or variation of normals, statistical properties, angles and continuity, etc… ; • the resulting surface mesh is manifold. This is a pre-industrial version that may contain some limitations. Your feedback is gladly welcome and will assess where we stand with respect to user expectations. Feel free to ask for your free test license !!! |
