OpenGL version of the classic shadow mapping algorithm to produce hard shadows

1. SUMMARY This demo performs a classic shadow mapping using OpenGL.

2. REQUIREMENTS TO RUN THE EXE

   • OpenGL runtimes installed (glu32.dll, glut32.dll)

3. HOW TO PLAY THE DEMO

   • +/- => Zoom the camera

4. HOW TO COMPILE

   • Microsoft Visual Studio 2005.

   • Microsoft Platform SDK (only needed if using VS Express Edition). In order to setup Visual C++ 2005 Express Edition with the Microsoft platform SDK you probably need to read this: http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/

   • Microsoft Windows OpenGL 1.2+ libraries for linking (glu32.lib). This should be already present in your VS installation.

   • OpenGL Utility Toolkit (GLUT) for Win32 which can be dowloaded from: http://www.xmission.com/~nate/glut.html

5. CODE STURCTURE

   • The main program creates and starts an instance of a GLApp which inherits from the abstract class GraphicsApp (which is used in other of my demos either with OpenGL or DX).

   • "GraphicsApp" creates the main windows application loop and the window display (i.e. the basic windows stuff).

   • "GLApp" takes care of processing the messages, initialize the OpenGL engine and render the demo scene.

   • "Geometry" class methods are called from GLApp and they take care or rendering the actual scene, set lights and cameras and materials.

   • "Timer" class by Adam Hoult which handles all timing functionality such as counting the number of frames per second, etc.
