Protect interactive 3D models via vertex shader programming

Abstract

In 3D games, virtual museum and other interactive environments, 3D modes are commonly used interactively. Many of these models are valuable and require protection from misuse such as unlawful exhibition, vicious distribution etc. A practical solution is to avoid the interactive user to reconstruct precise 3D models from data stream between applications and 3D APIs (such as Direct3D, OpenGL, etc) under condition of not affecting interaction. The scheme proposed in this paper protects 3D modes via vertex shader programming. The data of 3D models are encrypted in 3D application first and then decrypted in vertex shader. © IFIP International Federation for Information Processing 2005.
