Enumeration Type Documentation

daydream_input_index

enum daydream_input_index

Indices where each input is in the input list.

Function Documentation

daydream_get_fusion_pose()

static void daydream_get_fusion_pose ( struct daydream_device *  daydream, enum xrt_input_name  name, struct xrt_space_relation *  out_relation  )

static

Todo:

assuming that orientation is actually currently tracked.

References m_imu_3dof::rot.

daydream_read_one_packet()

static bool daydream_read_one_packet ( struct daydream_device *  daydream, uint8_t *  buffer, size_t  size  )

static

Reads one packet from the device,handles locking and checking if the thread has been told to shut down.

daydream_run_thread()

static void * daydream_run_thread ( void *  ptr )

static

Todo:

this should be injected at construction time
