Claim:
A method comprising: receiving, by a device via a network from an image generator controller, virtual environment (VE) model data identifying at least a portion of a VE, and a first viewpoint location and a first window definition; determining, by the device, a first view frustum in the VE based on the first viewpoint location and the first window definition, and a second view frustum in the VE; and for each cycle of a plurality of cycles over a period of time: intersecting, the device, the VE model data by the first view frustum and the second view frustum to identify first scene data and second scene data, respectively; processing, by a first graphics subsystem of the device, the first scene data to generate a first image; processing, by a second graphics subsystem of the device in parallel with the first graphics subsystem, the second scene data to generate a second image; and outputting the first image and the second image for display.
