我遇到了从Petrel中的TriangleMesh创建FractureNetwork的问题。绘制时，你可以看到所有单独的三角形 - 我希望它会是实心的。有些三角形看起来似乎是连在一起的，而不是全部。我错过了什么，或者是否有一个技巧让FractureNetwork看起来很稳固？
TriangleMesh是可靠的，当我在3D窗口中打开Wireframe时，它看起来也是正确的。链接显示图像与FractureNetwork旁边的TriangleMesh。

问题似乎是用于生成三角形的索引的顺序。
当使用以下代码生成裂缝网络时，三角形将以阴影显示。
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，如果修改了索引的顺序，则断裂网络是稳固的。
