Detailed Description
One camera exposure the HMD told us about, held so that late frames can still find the exposure they belong to.
Field Documentation
◆ recv_timestamp_ns
| timepoint_ns rift_exposure_event::recv_timestamp_ns |
When the IN report announcing this exposure arrived, in local monotonic time.
Frames are matched against this rather than against timestamp_ns. Both the report and the frame have travelled over USB before we see them, so their arrival times share most of that delay and land near each other; the exposure instant on the HMD's own clock is a good deal earlier than either.
