Mesh — Aspose.3D FOSS for .NET
Namespace: Aspose.ThreeD.Entities (Aspose.3D.Converter 1.0.0)
Mesh gemmer polygongeometri som en liste over kontrolpunkter (vertex positions) og en liste over polygonflader. Hver polygonflade er en liste over nulbaserede indekser i kontrolpunkternes array. Yderligere per-vertex-data – normals, UV coordinates, vertex colours – er vedhæftet som VertexElement lag.

Example
Byg et enkelt trekants‑mesh fra bunden:
using Aspose.ThreeD;
using Aspose.ThreeD.Entities;
// Create the mesh and add three vertex positions
var mesh = new Mesh();
mesh.ControlPoints.Add(new Vector4(0.0, 0.0, 0.0, 1.0)); // vertex 0
mesh.ControlPoints.Add(new Vector4(1.0, 0.0, 0.0, 1.0)); // vertex 1
mesh.ControlPoints.Add(new Vector4(0.5, 1.0, 0.0, 1.0)); // vertex 2
// Define one triangle face using vertex indices
mesh.CreatePolygon(0, 1, 2);
// Attach to a scene and save
var scene = new Scene();
scene.RootNode.CreateChildNode("triangle", mesh);
scene.Save("triangle.stl");Byg fra en primitiv og inspicer:
var sphere = new Sphere(1);
var mesh = sphere.ToMesh();
Console.WriteLine("Vertices: " + mesh.ControlPoints.Count);
Console.WriteLine("Polygons: " + mesh.PolygonCount);Example
