RecalculateNormals, adding new vertices

I'm adding new vertices to a plane, in order to deform the plane, but when I add the vertices the plane stays the same, it's not deformed. Does anyone ever bumped into this situation? How can I solve it?
My thanks in advanced.

I've uploaded the PrtScr, that shows the news vertices being created but without deforming the plane.


This is my code to add vertices

Code (csharp):

1.  
2. public void AddSingleVertice()
3.     {
4.         mainObject=GameObject.Find("Plane");
5.        
6.         Mesh mesh = new Mesh ();
7.        
8.         mesh.Clear ();
9.        
10.         mesh = mainObject.GetComponent<MeshFilter> ().mesh;
11.  
12.         Script_Global.p_vertices.Clear();      
13.  
14.         Vector3[] vertices=mesh.vertices ;
15.         Vector3[] vertices2=new Vector3[vertices.Length+2];
16.         Vector3 V3;
17.  
18.         float val=-2.111f;
19.         float vx=-0.222f;
20.  
21.         vertices.CopyTo(vertices2,0);
22.        
23.         vertices2[vertices.Length]=new Vector3(vertices[0].x+vx,vertices[0].y+1,vertices[0].z);
24.         vertices2[vertices.Length+1]=new Vector3(vertices[0].x+1,vertices[0].y+2,vertices[0].z);
25.        
26.  
27.         Debug.Log("Vertice1: " + vertices.Length.ToString());
28.         Debug.Log("Vertice2: " + vertices2.Length.ToString());
29.  
30.         foreach (var item in vertices2) {
31.             Debug.Log("Vertice X value: " + item.x.ToString() + " Vertice Y value: " + item.y.ToString() + " Vertice Z value: " + item.z.ToString());
32.            
33.             V3=new Vector3(item.x,item.y,item.z);          
34.            
35.            
36.             Script_Global.p_vertices.Add(V3);
37.         }
38.  
39.         mesh.vertices=vertices2;
40.         mesh.RecalculateNormals();
41.     }
42.  

 

Vertices themselves are just points. You need to connect them and create triangles or quads.

Detail: You don't have to create a new mesh when you get the one from a mesh filter anyway.

 

Is there any automatic way to do that? a function that receives the values and connects them?

 

No, at least not in Unity. When you add vertices in Unity, you have to create the corresponding triangles along with it. I am also not aware of something in the asset store that would help you with that.

 

You have to write a script that connects all them points/vertices and form triangles. Like Dantus said, 'Vertices themselves are just points.'
You should create your own gameobject with a custom mesh instead of using the plane, that way you should have more control over the ammount and position of vertices that you want, but brace yourself, it may get complicated
