Linux support added to python-ovrsdk.

Link: http://www.tyrovr.com/2014/06/02/python-ovrsdk.html

example:

    
    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)


output:

    You may wish to take a look at my fork here. I've made a number of changes to the code.


    • Renamed the package to 'oculusvr'

    • Renamed the mapped ovr structure types to be more GL/python-like: ovrMatrix4f becomes mat4, ovrHmdDesc becomes hmd_desc, etc

    • Consolidated the python code into a single file in the top level package __init__.py. Your windows/wrapper.py and linux/wrapper.py are nearly identical. There's not much point in keeping them as separate files

    • Added the DLL's I've built for my Java bindings, which includes 32 and 64 bit dlls for windows and 64 bit dlls for Linux and OSX.

    • Added the proper license file, since generated code based off the Oculus headers would be covered under the same license as the Oculus SDK itself.

    • Added a friendly wrapper class Rift, which lets you have access to all the functionality with a more python-like interface. Many of the functions in the C API are mapped with reasonable default values. See the sample below.


    My updated example code looks like this:


    import time
    from oculusvr import Rift

    Rift.initialize()

    rift = Rift()
    time.sleep(0.1)
    rift.start_sensor()
    hmdDesc = rift.get_desc()
    print hmdDesc.ProductName
    print hmdDesc.MaxEyeFov[0].UpTan


    while True:
        ss = rift.get_sensor_state()
        pose = ss.Predicted.Pose
        print "%10f   %10f   %10f   %10f" % ( \
            pose.Orientation.w, 
            pose.Orientation.x, 
            pose.Orientation.y, 
            pose.Orientation.z
        )
        time.sleep(0.5)

    rift.destroy()
    rift = None
    Rift.shutdown()

    Look very interesting!
    I did not look into oculus / python connection yet , is there some 3d framework that can be used with your wrapper?

    keep up the good work!:)

    I've used pyglet with it in the past, and things went swimmingly. I believe there are a number of people working on more modern solutions, but I am am unaware of anything that has yet come to fruition.
