1. A method of displaying 3D imagery comprising: receiving layout data comprising data representing a first camera; generating a first pair of a left camera and a right camera from the layout data based on the first camera, wherein the left camera and the right camera are editable; retrieving, from an external memory in a streaming manner, streaming geometry data corresponding to the layout data and copying the streaming geometry data to an internal graphics memory; and generating the 3D imagery using the first pair of the left camera and the right camera and the streaming geometry data; wherein the streaming geometric data stored in the external memory is formatted to be mapped directly into the internal graphics memory; and wherein the retrieving and copying step comprises directly copying the streaming geometry data streamed from the external memory onto the internal graphics memory without aligning or processing the geometry data.
