“Rotation Of Earth” Project simulate the rotation of the Earth with different tilting angle, Radius of the Earth and so on. This Project is coded in C# Programming language based on .NET platform. Different functions of GDI+ graphic library are used for the 2D rendering and manipulations. The 2D map of the World map is wrapped in 3D sphere using proportional equations and then it is projected in the 2D plane. The visible surface is detected using z-buffer method.
