  • Patent number: 11368351
    Abstract: A simulation view network streamer is disclosed. A first request is received to generate a first network view stream from a first view that exists in a simulation of a virtual environment. The first view is defined by first view data that identifies a first portion of the virtual environment encompassed by the first view. The first request includes a first destination address of a first output device. A second request is received to generate a second network view stream from a second view that exists in the simulation of the virtual environment concurrently with the first view, the second request including a second destination address of a second output device. A stream of images of the first view is sent to the first output device, and a stream of images of the second view is sent to the second output device.

  • Patent number: 10657717
    Abstract: A simulator is disclosed. A cockpit model comprising a plurality of cockpit model parts that collectively correspond to a simulated cockpit in a simulated vehicle is maintained. For each frame of a plurality of frames, a plurality of cockpit view frustums are determined, each cockpit view frustum corresponding to a different cockpit view of a plurality of cockpit views of the simulated cockpit. Shared cockpit scene information comprising a set of cockpit model parts that are within any of the plurality of cockpit views is generated based on the plurality of cockpit view frustums. A processing device submits to a graphics processing unit (GPU) the shared cockpit scene information and GPU instructions that direct the GPU to generate a plurality of cockpit view images that correspond to the plurality of cockpit views from the shared cockpit scene information. The GPU generates the plurality of cockpit view images.
