Selecting Portions of Vehicle-Captured Video to Use for Display

A video display system comprising:

• a rendering map including a mapping of texture frame coordinates to virtual hemisphere or sphere coordinates for a viewing device, the rendering map having been generated during an initialization process of the viewing device;
• a communication component configured to receive, from a camera system of a vehicle, multiple video frames including a first video frame;
• a first texture frame buffer storing the first video frame after receipt of the video frame from the vehicle;
• a mapping module configured to determine texture values for a virtual hemisphere or sphere based on the rendering map and the first video frame in the first texture frame buffer;
• and
• a display module configured to provide, to the viewing device, pixel values for the viewing device to display the video frame.

A computing device comprising:

• one or more processors;
• a computer-readable storage medium having stored thereon multiple instructions that, responsive to execution by the one or more processors, cause the one or more processors to perform acts comprising:
• obtaining a rendering map of texture frame coordinates to virtual sphere coordinates for a viewing device;
• receiving a first video frame of multiple video frames from a vehicle;
• saving the first video frame of the multiple frames into a first texture frame buffer;
• using the rendering map and the first video frame in the first texture frame buffer to determine texture values for a virtual sphere;
• providing, to the viewing device, an indication of pixel values for the viewing device to display the first video frame;
• detecting a movement of the viewing device to a new position along one or more axes;
• and
• without waiting for a camera system of the vehicle to move in response to the movement of the viewing device:
• using the rendering map and a second frame of the multiple video frames to determine new texture values for the virtual sphere, the second frame reflecting the movement of the viewing device, and
• providing, to the viewing device, an indication of pixel values for the viewing device to display the second video frame.
