Abstract

Systems and methods for remotely displaying three dimensional graphical data, include a local computing machine that communicates with a remote computing machine via a connection. An application executing on the local computing machine, generates three dimensional graphics commands which are intercepted and transferred to either the remote computing machine or a computing element on the local computing machine. Determining where to transfer the three dimensional graphics commands requires: an analysis of the application to obtain application specific characteristics; an analysis of the remote computing machine to obtain the capabilities of the remote computing machine; an analysis of the local computing machine to obtain the capabilities of the local computing machine; and an analysis of the connection to determine characteristics of the connection. A determination is made in response to obtaining the application characteristics, the remote computing machine capabilities, the local computing machine capabilities and the connection characteristics.
