1. Introduction

The glAppGrapher is an interactive graphical server that allows clients to indirectly render three-dimensional objects. It is intended to be a debugging tool for software developers who need to visualize aspects of their programs without turning their programs upside-down in the process. This server, in conjunction with a properly written client side, has the potential to:

• Assist a programmer in debugging a physics engine or collision detection code through the visual output of certain objects and key vectors
• Allow the programmer to visualize BSP and other complex trees both topologically and graphically via spheres, planes and meshes, as well as what objects are associated with what nodes.
• Involve more than one computer.
• Do all of this in an interactive environment, even if the client process is halted.

1.1 Features

• Full OpenGL and GLU function support for both Windows and Linux builds. (That means you can call any OpenGL or GLU function in the entire library as long as you know the name and pass the in parameters correctly)
• Ability to navigate around the scene with the mouse
• A scalable interactive console (it currently does nothing)
• Full-Screen or Windowed support
• Uses Berkeley Socket function calls for communication between the glAppGrapher and clients
• Single glAppGrapher server supports multiple clients.
