MeshDataTool
============
**继承：** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
用于访问和编辑 :ref:`Mesh<class_Mesh>` 数据的辅助工具。
.. rst-class:: classref-introduction-group
描述
----
MeshDataTool 提供对 :ref:`Mesh<class_Mesh>` 中各个顶点的访问。它允许用户读取和编辑网格的顶点数据。它还创建了一系列面和边。
要使用 MeshDataTool，请使用 :ref:`create_from_surface()<class_MeshDataTool_method_create_from_surface>` 加载一个网格。完成数据编辑后，使用 :ref:`commit_to_surface()<class_MeshDataTool_method_commit_to_surface>` 将数据提交到一个网格。
下面是如何使用 MeshDataTool 的示例。
.. tabs::
.. code-tab:: gdscript
var mesh = ArrayMesh.new()
mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, BoxMesh.new().get_mesh_arrays())
var mdt = MeshDataTool.new()
mdt.create_from_surface(mesh, 0)
for i in range(mdt.get_vertex_count()):
var vertex = mdt.get_vertex(i)
# 在这个例子中，我们将网格挤出一个单位，这会导致分离的面，因为它是平直着色的。
vertex += mdt.get_vertex_normal(i)
# 保存你的更改。
mdt.set_vertex(i, vertex)
mesh.clear_surfaces()
mdt.commit_to_surface(mesh)
var mi = MeshInstance.new()
mi.mesh = mesh
add_child(mi)
.. code-tab:: csharp
var mesh = new ArrayMesh();
mesh.AddSurfaceFromArrays(Mesh.PrimitiveType.Triangles, new BoxMesh().GetMeshArrays());
var mdt = new MeshDataTool();
mdt.CreateFromSurface(mesh, 0);
for (var i = 0; i < mdt.GetVertexCount(); i++)
{
Vector3 vertex = mdt.GetVertex(i);
// 在这个例子中，我们将网格挤出一个单位，这会导致分离的面，因为它是平直着色的。
vertex += mdt.GetVertexNormal(i);
// 保存你的更改。
mdt.SetVertex(i, vertex);
}
mesh.ClearSurfaces();
mdt.CommitToSurface(mesh);
var mi = new MeshInstance();
mi.Mesh = mesh;
AddChild(mi);
另见 :ref:`ArrayMesh<class_ArrayMesh>`\ 、\ :ref:`ImmediateMesh<class_ImmediateMesh>` 和 :ref:`SurfaceTool<class_SurfaceTool>`\ ，以了解程序化几何生成。
