Mesh
Espacio de nombres: Aspose.ThreeD.Entities (Aspose.3D.Converter 1.0.0)
Mesh almacena la geometría del polígono como una lista de puntos de control (posiciones de los vértices) y una lista de caras del polígono. Cada cara del polígono es una lista de índices basados en cero en el arreglo de puntos de control. Los datos adicionales por vértice – normales, coordenadas UV, colores de vértice – se adjuntan como VertexElement capas.

Methods
Construye una malla de triángulo único desde cero:
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");Construir a partir de un primitivo e inspeccionar:
var sphere = new Sphere(1);
var mesh = sphere.ToMesh();
Console.WriteLine("Vertices: " + mesh.ControlPoints.Count);
Console.WriteLine("Polygons: " + mesh.PolygonCount);Methods
