python-ovrsdk

Cross-platform wrapper for the Oculus VR SDK C API

Works on Linux and Windows. Precompiled Oculus VR SDK shared library included, so just install it and go.

Installation

pip install python-ovrsdk

Use

import time
from ovrsdk import *

ovr_Initialize()
hmd = ovrHmd_Create(0)
hmdDesc = ovrHmdDesc()
ovrHmd_GetDesc(hmd, byref(hmdDesc))
print hmdDesc.ProductName
ovrHmd_StartSensor( \
  hmd, 
  ovrSensorCap_Orientation | 
  ovrSensorCap_YawCorrection, 
  0
)

while True:
  ss = ovrHmd_GetSensorState(hmd, ovr_GetTimeInSeconds())
  pose = ss.Predicted.Pose
  print "%10f   %10f   %10f   %10f" % ( \
    pose.Orientation.w, 
    pose.Orientation.x, 
    pose.Orientation.y, 
    pose.Orientation.z
  )
  time.sleep(0.016)
