[Record] Draw a Cube with Unity3D via Creat an object,get Mesh,set Mesh and Render Mesh

Tools: Unity3D (5.5),VS2015, C#
Test environment: Hololens (UWP)
Some code come from WEB,Thanks for the beginner!

Tips:
1.Creat an object,get mesh,set mesh,render mesh and move it!
That is a very important path for custom model which beyond .OBJ,.FBX,.Unity ,ect;
and there is also a shortcut for the path Drawmesh:Graphics(for Unity Pro only).

2.Draw a triangle in unclockwise! Otherwise you will see through into the cube; and get wrong texture fixed.

3.Use Asset.Resources.Load(“”) to get your picture which used for texture and convert to class Texture like :
(Texture)Resources.Load(“background”);

4.If you have a model,you would get the Vertexs,triangels,normals,UV,UV2,and textures; first two are important!

5.I think I can give every gameobject I draw a script to control it,like this:
m_mesh.AddComponent< rotate >();
GameObject.Find(“createMesh_JQM”).SendMessage(“scale”);

That`s all.
