Detailed Description
Driver for the Oculus Rift.
Based largely on simulated_hmd.c, with reference to the DK1/DK2 firmware and OpenHMD's rift driver.

Creates Rift HMD and related devices.
- Parameters
-
hmd_dev The HID device for the HMD. radio_dev The HID device for the radio, if present (CV1 only). variant The Rift variant (DK2 or CV1). serial_number The serial number of the device. xfctx The frame context to use for the timing source functions. This is optional if you do not plan to use the Rift as a timing source. out_hmd Output pointer for the created rift_hmd struct. out_xdevs Output array for the created xrt_device pointers. The array must have space for at least 4 devices (HMD, left touch, right touch, remote).
- Returns
- The number of devices created, or a negative value on error.

◆ rift_hmd_get_timing_event_source()
| struct t_timing_event_source * rift_hmd_get_timing_event_source | ( | struct rift_hmd * | hmd | ) |
Gets the HMD's timing event source.
- Parameters
-
hmd The rift_hmd to get the timing event source from.
- Returns
- The timing event source for the HMD, or NULL if the timing source is not initialized.
