Returns a copy of the vertex positions or assigns a new vertex positions array.

The number of vertices in the mesh is changed by assigning a vertex array with a different number of vertices. Note that if you resize the vertex array then all other vertex attributes (normals, colors, tangents, UVs) will be automatically resized too. RecalculateBounds will automatically be invoked if no vertices have been assigned to the mesh when setting the vertices.

		var mesh : Mesh = GetComponent(MeshFilter).mesh;
		var vertices : Vector3[] = mesh.vertices;
		for (var i = 0; i < vertices.Length; i++)
			vertices[i] += Vector3.up * Time.deltaTime;
		mesh.vertices = vertices;
		mesh.RecalculateBounds();
	}
