![]() ![]() Vector3d vertexA = new Vector3d(vertexBuffer, vertexBuffer, vertexBuffer) Get the vertex positions for the three vertices of the triangle Remove the zero-area triangles from the index bufferįor (int i = 0 i < indexBuffer.Length i += 3) I implemented this method to remove triangles with zero area: public static int RemoveZeroAreaTriangles(int indexBuffer, float vertexBuffer) ON_Mesh.m_F.vi has invalid vertex indices.Īnd after the output mesh is added to the Rhino document, as soon as I zoom in or out, the mesh disappears. It means there is nothing critical wrong with the output mesh. The bool isValid = meshOut.Check(log, ref parameters) statement returns true. Surprisingly, this is the prompt message:Īnd this is the content of the mesh check log file: RhinoApp.WriteLine("Is output mesh valid? ", isValid) log = new ("log-mesh-checks-hollowing.txt") īool isValid = meshOut.Check(log, ref parameters) Parameters.CheckForUnusedVertices = true Parameters.CheckForSelfIntersection = true Parameters.CheckForRandomFaceNormals = true ![]() Parameters.CheckForNonManifoldEdges = true Parameters.CheckForExtremelyShortEdges = true Parameters.CheckForDuplicateFaces = true Parameters.CheckForDisjointMeshes = true Parameters.CheckForDegenerateFaces = true MeshCheckParameters parameters = new MeshCheckParameters() The specific algorithm that is best suited for your needs may vary depending on the geometry of your mesh and the specific requirements of your application.I tried the Check method of C# Mesh class and enabled all of its checks: // Run the CheckValidity method on the mesh. These are just a few examples of algorithms that can be used to close gaps in meshes. ![]() This can be particularly useful for closing gaps on meshes with irregular geometry. Geodesic Path: Geodesic path algorithms generate a path between the two edges of the gap, and then generate new faces to fill the gap along this path.These patches can then be used to generate new faces to close the gap. Patching: Patching algorithms involve generating a set of patches that fit the geometry of the mesh around the gap.It can also be used to close gaps in meshes by generating a set of new faces that fit the geometry of the mesh around the gap. Marching Cubes: Marching Cubes is an algorithm that is commonly used for creating a mesh from a scalar field.This surface can then be used to generate new faces to close the gap. Surface Fitting: Surface fitting algorithms use mathematical models to generate a surface that fits the geometry of the mesh around the gap.Triangulation can be performed using a variety of techniques, such as Delaunay triangulation or ear clipping. It involves generating a set of new triangles to fill the gap in the mesh. Triangulation: Triangulation is a common algorithm used to close gaps in meshes.There are several algorithms that can be used to close a gap on a mesh. This is not a trivial task you are faced with… It can fix common issues such as holes, non-manifold geometry, and self-intersections, and can be particularly useful for preparing meshes for use in 3D printing and other applications. Microsoft MeshLab: Microsoft MeshLab is a cloud-based service that uses AI algorithms to automatically repair and optimize 3D meshes.It uses AI algorithms to automatically repair and optimize meshes, and can be particularly useful for preparing meshes for use in manufacturing applications. Autodesk Netfabb: Autodesk Netfabb is a commercial software suite that includes a variety of tools for working with 3D meshes.It can fix common issues such as holes, self-intersections, and non-manifold geometry, and can be particularly useful for preparing meshes for use in other applications. MeshFix: MeshFix is a tool that uses machine learning algorithms to automatically repair and optimize 3D meshes.It can be particularly useful for tasks such as remeshing and mesh optimization. Instant Meshes: Instant Meshes is a free and open-source tool that uses AI algorithms to generate a high-quality quad mesh from a given input mesh.So I ask:ĬhatGPT: Yes, there are several AI tools available for fixing meshes, particularly for tasks such as mesh repair and optimization. I ask chatCPT how to fix a mesh in babylon.js - but no working answer. ![]()
