python-ovrsdk 0.2.0

Python wrapper for Oculus VR SDK.

Cross-platform wrapper for the Oculus VR SDK C API

Actually, it’s not terribly cross-platform, yet. It’s only supported on windows because the current release of the SDK is only available for Windows. As soon as Linux and OSX becomes available, I’ll be updating it to support them.

Installation

pip install python-ovrsdk

Use

from ovrsdk import *

ovr_Initialize()
hmd = ovrHmd_Create(0)
hmdDesc = ovrHmdDesc()
ovrHmd_GetDesc(hmd, byref(hmdDesc))
print hmdDesc.ProductName
ovrHmd_StartSensor( \
    hmd, ovrHmdCap_Orientation | ovrHmdCap_YawCorrection |
    ovrHmdCap_Position | ovrHmdCap_LowPersistence,
    ovrHmdCap_Orientation
)

while True:
    ss = ovrHmd_GetSensorState(hmd, 0.0)
    pose = ss.Predicted.Pose
    print "%10f   %10f   %10f   %10f" % ( \
        pose.Orientation.w,
        pose.Orientation.x,
        pose.Orientation.y,
        pose.Orientation.z
    )

ovrHmd_Destroy(hmd)
ovr_Shutdown()
