Real Time Game Figures Interception and Processing

Omer Ofir and Roey Ben Haim, Spring 2007

Project Overview

Recent developments in computer games and in Interactive TV have led to the creation of new gaming applications such as interactive gaming (game played by a couple of players) and more. With that in mind, these projects aim at achieving real-time interception of game figures allowing the player full visibility of the figure's behavior.

The game interception is based on DirectX rendering commands from the CPU to the Graphical Processing Unit (GPU). This data is further processed in real-time by the GPU to estimate the figure's 3D structure including position motion and more.

This kind of experiment with a final product can be seen as Reverse Engineering, as we try to get information and to manipulate a given package – a binary game or graphical application. It is used in many and various aspects of science, from machine engineering to physics, and using it we can educate ourselves from a given final work, and perhaps to enrich the product itself with our insights.

Several products that are purposed to the same goal exist, for example graphic remedy’s gDebugger, which perform interception of real time binary application that uses openGL, and contain different Debugging tools such as breakpoints and stepping over given commands sent to the OpenGL API, graphic profiling and so on.

In this project we try to reach a lower level result then the example mentioned above, while doing so to the DirectX API instead of the OpenGL one, and to try and capture a certain geometry model\s within the game.
