Issue drawing FractureNetwork from三角网格在Petrel

Question

我在从Petrel的三角网格创建FractureNetwork时出现问题。当它被绘制时，你可以看到所有的单个三角形 - 我预计它会很稳定。有些三角形好像是连通的，但不是全部。我是否错过了一些东西，或者有没有让FractureNetwork显得稳固的技巧？

TriangleMesh是稳定的，当我在3D窗口中打开Wireframe时，它看起来也是正确的。链接使用FractureNetwork旁边的TriangleMesh显示图像。

这个问题似乎已经在用于生成三角形索引的顺序。

当下面的代码用于生成裂缝网络时，三角形被加阴影。

public static void Test() 
    { 
     Point3[] vertices = new Point3[9]; 
     IndexedTriangle[] triangles = new IndexedTriangle[8]; 

     vertices[0] = new Point3(0, 100, 0); 
     vertices[1] = new Point3(50, 100, 5); 
     vertices[2] = new Point3(100, 100, 10); 
     vertices[3] = new Point3(0, 50, 15); 
     vertices[4] = new Point3(50, 50, 20); 
     vertices[5] = new Point3(100, 50, 25); 
     vertices[6] = new Point3(0, 0, 30); 
     vertices[7] = new Point3(50, 0, 35); 
     vertices[8] = new Point3(100, 0, 40); 

     triangles[0] = new IndexedTriangle(0, 1, 3); 
     triangles[1] = new IndexedTriangle(1, 3, 4); 
     triangles[2] = new IndexedTriangle(1, 2, 4); 
     triangles[3] = new IndexedTriangle(2, 4, 5); 
     triangles[4] = new IndexedTriangle(3, 4, 6); 
     triangles[5] = new IndexedTriangle(4, 6, 7); 
     triangles[6] = new IndexedTriangle(4, 5, 7); 
     triangles[7] = new IndexedTriangle(5, 7, 8); 

     IndexedTriangleMesh triangleMesh = new IndexedTriangleMesh(triangles, vertices, null); 

     TriangleMesh triMesh = null; 
     using (ITransaction trans = Slb.Ocean.Core.DataManager.NewTransaction()) 
     { 
      Project proj = PetrelProject.PrimaryProject; 
      trans.Lock(proj); 
      string colName = "TringleMeshes"; 
      Collection collection = Collection.NullObject; 
      collection = proj.CreateCollection(colName); 

      trans.Lock(collection); 

      DomainObjectExtensionRoot root = DomainObjectExtensionRoot.GetInstance(); 
      trans.Lock(root); 

      triMesh = root.CreateTriangleMesh("TestMesh", Domain.ELEVATION_DEPTH, collection, "Test", ""); 
      trans.Lock(triMesh); 
      triMesh.IndexedTriangleMeshes = new IndexedTriangleMesh[] { triangleMesh }; 
      triMesh.Color = Color.Blue; 
      trans.Commit(); 
     } 

     Project project = PetrelProject.PrimaryProject; 


     FractureNetwork fractureNetwork;     

     using (ITransaction trans = Slb.Ocean.Core.DataManager.NewTransaction()) 
     { 
      trans.Lock(project); 

      fractureNetwork = project.CreateFractureNetwork("FractureNetwork", Domain.ELEVATION_DEPTH); 

      fractureNetwork.CreateFracturePatches(triMesh.IndexedTriangleMeshes); 

      trans.Commit(); 
     } 

    } 

但是，如果索引的顺序被修改，断裂网络是固体的。

public static void Test() 
    { 
     Point3[] vertices = new Point3[9]; 
     IndexedTriangle[] triangles = new IndexedTriangle[8]; 

     vertices[0] = new Point3(0, 100, 0); 
     vertices[1] = new Point3(50, 100, 5); 
     vertices[2] = new Point3(100, 100, 10); 
     vertices[3] = new Point3(0, 50, 15); 
     vertices[4] = new Point3(50, 50, 20); 
     vertices[5] = new Point3(100, 50, 25); 
     vertices[6] = new Point3(0, 0, 30); 
     vertices[7] = new Point3(50, 0, 35); 
     vertices[8] = new Point3(100, 0, 40); 

     triangles[0] = new IndexedTriangle(0, 1, 3); 
     triangles[1] = new IndexedTriangle(1, 4, 3); // switched order of last two values 
     triangles[2] = new IndexedTriangle(1, 2, 4); 
     triangles[3] = new IndexedTriangle(2, 5, 4); // switched order of last two values 
     triangles[4] = new IndexedTriangle(3, 4, 6); 
     triangles[5] = new IndexedTriangle(4, 7, 6); // switched order of last two values 
     triangles[6] = new IndexedTriangle(4, 5, 7); 
     triangles[7] = new IndexedTriangle(5, 8, 7); // switched order of last two values 

     IndexedTriangleMesh triangleMesh = new IndexedTriangleMesh(triangles, vertices, null); 

     TriangleMesh triMesh = null; 
     using (ITransaction trans = Slb.Ocean.Core.DataManager.NewTransaction()) 
     { 
      Project proj = PetrelProject.PrimaryProject; 
      trans.Lock(proj); 
      string colName = "TringleMeshes"; 
      Collection collection = Collection.NullObject; 
      collection = proj.CreateCollection(colName); 

      trans.Lock(collection); 

      DomainObjectExtensionRoot root = DomainObjectExtensionRoot.GetInstance(); 
      trans.Lock(root); 

      triMesh = root.CreateTriangleMesh("TestMesh", Domain.ELEVATION_DEPTH, collection, "Test", ""); 
      trans.Lock(triMesh); 
      triMesh.IndexedTriangleMeshes = new IndexedTriangleMesh[] { triangleMesh }; 
      triMesh.Color = Color.Blue; 
      trans.Commit(); 
     } 

     Project project = PetrelProject.PrimaryProject; 


     FractureNetwork fractureNetwork;     

     using (ITransaction trans = Slb.Ocean.Core.DataManager.NewTransaction()) 
     { 
      trans.Lock(project); 

      fractureNetwork = project.CreateFractureNetwork("FractureNetwork", Domain.ELEVATION_DEPTH); 

      fractureNetwork.CreateFracturePatches(triMesh.IndexedTriangleMeshes); 

      trans.Commit(); 
     } 

    }
