Shrink wrap mesh

Just about anything! Plug-in developers can now access static ShrinkWrap methods from the Mesh class in RhinoCommon as well as on mesh.

A Cartesian shrink wrapping technique has been investigated in this study to construct triangular surface meshes for three-dimensional dirty geometries. The geometries dealt in this paper are defined by faceted representation with dirtiness such as nonconforming edges, gaps and overlaps. The objective of the proposed technique is to deliver a way constructing triangular surface meshes for upstream solutions in design processes without extensive labors for healing dirtiness in complicated dirty geometries. A Cartesian grid is overlaid onto the dirty geometries and its cells are adaptively refined until target resolution is achieved while recording intersections with geometric facets in cells. An initial watertight shell called the wrapper surface is constructed by selectively extracting the boundary sides of intersected cells. The wrapper surface is improved by a subsequence of operations such as projecting nodes onto geometry, adjusting nodes on the geometry and editing local triangular faces to achieve better approximation.

The resulting meshes consist of triangles with similar edge lengths, angles and areas. This will be included in Grasshopper in the next Rhino 7 service release candidate. It can detect and robustly preserve sharp features and boundaries and produces conforming meshes which match edge-to-edge including across creases without hidden slivers in concave regions - a common problem with other remeshers. Features can either be inferred from the edges of an input Brep, detected from mesh face angles, or input directly as curves or points to keep fixed. It also outputs the dual mesh. Because the triangular meshes have connectivity, this dual mesh consists mainly of hexagons, with some pentagons and heptagons. It also optimizes so that these Ngons also have similar areas and edge lengths. This even allows the used of a bad mesh as the target, with holes, non-manifold edges and duplicate faces.

Point2Mesh is a technique for reconstructing a surface mesh from an input point cloud. This approach "learns" from a single object, by optimizing the weights of a CNN to deform some initial mesh to shrink-wrap the input point cloud. The argument for going this route is: since the local convolutional kernels are optimized globally across the entire shape, this encourages local-scale geometric self-similarity across the reconstructed shape surface. The code was written by Rana Hanocka and Gal Metzer. This code relies on the Robust Watertight Manifold Software. First cd into the location you wish to install the software.

Thanks theoutside , To preserve hard edges, one needs to keep the Target Edge Length quite low. You can determine the level of detail retained by determining the mesh size to use, among other options. Learn about the different types of mesh you can create in HyperWorks. Loose Shrink Wrap Mesh Loose wrap wraps the selected elements or components, surfaces, or solids with the target element size specified, and outputs an outer-volume mesh which approximately adheres to the original FE topology. A lot of potential use cases IMHO…. Multi-disciplinary design exploration and optimization tools. I wanted to test going from a very loose surface definition, typical of early-stage design, to a closed and softened mesh ready for the printer. The algorithm is always going to try to achieve a near uniform target edge length based on your input.
