-====
-
-In this tutorial you will learn how to
-
-.. container:: enumeratevisibleitemswithsquare
-
-  * Open a visualization window.
-  * Access a window by its name.
-  * Start event loop.
-  * Start event loop for a given amount of time.
-
-Code
-====
-
-You can download the code from `here <../../../../samples/cpp/tutorial_code/viz/launching_viz.cpp>`_.

-            /// Event loop for 1 millisecond
-            sameWindow.spinOnce(1, true);
-        }
-        
-        /// Once more event loop is stopped
-        cout << "Last event loop is over" << endl;
-        return 0;
-    }
-    
-Explanation
-===========
-
-Here is the general structure of the program:
-
-* Create a window.
-
-.. code-block:: cpp
-
-    /// Create a window
-    viz::Viz3d myWindow("Viz Demo");
-    
-* Start event loop. This event loop will run until user terminates it by pressing **e**, **E**, **q**, **Q**.
-
-.. code-block:: cpp
-
-    /// Start event loop
-    myWindow.spin();
-    
-* Access same window via its name. Since windows are implicitly shared, **sameWindow** is exactly the same with **myWindow**. If the name does not exist, a new window is created.
-
-.. code-block:: cpp
-
-    /// Access window via its name
-    viz::Viz3d sameWindow = viz::get("Viz Demo");
-    
-* Start a controlled event loop. Once it starts, **wasStopped** is set to false. Inside the while loop, in each iteration, **spinOnce** is called to prevent event loop from completely stopping. Inside the while loop, user can execute other statements including those which interact with the window.
-
-.. code-block:: cpp
-
-    /// Event loop is over when pressed q, Q, e, E
-    /// Start event loop once for 1 millisecond
-    sameWindow.spinOnce(1, true);
-    while(!sameWindow.wasStopped())
-    {
-        /// Interact with window
-        
-        /// Event loop for 1 millisecond
-        sameWindow.spinOnce(1, true);
-    }
-

-Here is the result of the program.
