Detailed Description

Extends the trackable state by information on the buttons, input axes and vibration strengths.

extends the trackable state by a vr_controller_state::time_stamp, vr_controller_state::button_flags, vr_controller_state::axes[vr::max_nr_controller_axes], and vr_controller_state::vibration[2] There are 7 buttons as listed in vr::VRButtonStateFlags, where vr::VRF_STICK_TOUCH corresponds to touching of the stick|touchpad and vr::VRF_STICK to pressing it.The controller provides up to vr::max_nr_controller_axes axes, where the first two correspond to the stick|touchpad position and the third (vr_controller_state::axes[2]) to the trigger.

◆ pose

float vr::vr_trackable_state::pose[12]
inherited

pose as 3x4 matrix in column major format, where each column is a vector in world coordinates

  • pose[0..2] ... x-axis pointing to the right
  • pose[3..5] ... y-axis pointing up
  • pose[6..8] ... z-axis pointing backwards
  • pose[9..11] ... location of trackable's origin
