MeshDataTool
============
**繼承：** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
用於存取和編輯 :ref:`Mesh<class_Mesh>` 資料的輔助工具。
.. rst-class:: classref-introduction-group
說明
----
MeshDataTool 提供對 :ref:`Mesh<class_Mesh>` 中各個頂點的存取。它允許使用者讀取和編輯網格的頂點數據。它還建立了一系列面和邊。
要使用 MeshDataTool，請使用 :ref:`create_from_surface()<class_MeshDataTool_method_create_from_surface>` 載入一個網格。完成數據編輯後，使用 :ref:`commit_to_surface()<class_MeshDataTool_method_commit_to_surface>` 將資料提交到一個網格。
下面是如何使用 MeshDataTool 的範例。
.. 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)
# 在這個例子中，我們將網格擠出一個單位，這會導致分離的面，因為它是平直著色的。
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);
// 在這個例子中，我們將網格擠出一個單位，這會導致分離的面，因為它是平直著色的。
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);

|void| **set_vertex_tangent**\ (\ idx\: :ref:`int<class_int>`, tangent\: :ref:`Plane<class_Plane>`\ ) :ref:`🔗<class_MeshDataTool_method_set_vertex_tangent>`
Sets the tangent of the given vertex.
\ **Note:** Even though ``tangent`` is a :ref:`Plane<class_Plane>`, it does not directly represent the tangent plane. Its :ref:`Plane.x<class_Plane_property_x>`, :ref:`Plane.y<class_Plane_property_y>`, and :ref:`Plane.z<class_Plane_property_z>` represent the tangent vector and :ref:`Plane.d<class_Plane_property_d>` should be either ``-1`` or ``1``. See also :ref:`Mesh.ARRAY_TANGENT<class_Mesh_constant_ARRAY_TANGENT>`.
