 MVP is a methodology for showing the vertices in a comfortable way to present the object's local coorinates, camera, and perspective.
+
+In this tutorial, you can get the knowledge of what Model-View-Projection is, how to express different objects differently, and how to show the camera's view.

+You can see the change of the screen using these inputs and move the object and view point using different types of translations.
+The only object you can move in the world coordinate is the cube object which is in the middle.
