Broadcast GL: An Alternative Method for Distributing OpenGL API Calls to Multiple Rendering Slaves

Ilmonen, T., Reunanen, M., Kontio P.

This paper describes the use of UDP/IP broadcast for distributing OpenGL API calls. We present an overview of the system and benchmark its performance against other common distribution methods. The use of network broadcasts makes this approach highly scalable. The method was found effective for applications that need to transmit changing vertex arrays or textures frequently.
