If you wonder what that scribble is, it is a mountain (but since the mesh is to small, it looks like a scribble.) if you want, change the SIZE value.
So you create some vectors, you pair them into vertices then you cube them into matrices, then you add UV and Normals to the vertex, done. (In this test, the Normals are created, but not used.) You might also see some values " NaN " But it doesn't affect the project much.
