Thanks for your extraordinary work on vicon SDK with python3.

Do you have try your pyvicon in Windows?

I tried to do that. You guessed it, it didn't work.
Python interpreter told it could not open several .h and .lib files.
I found the same-name files from Nexus installation directory.
But I did not work.

So, would you try to change your pyvicon package to work on Windows? And add necessary include .h/.lib files? Thank you very much.

When I try to load into Mavproxy, pyvicon.py fails at line 1 "import pyvicon_module". Is that just a symbolic name for pyvicon.cpp? Where should that module be? Any help would be greatly appreciated.

Hi, I am trying to install pyvicon on macOS, but building 'pyvicon_module' extension keep failing, and it seems it is because it cannot link to libViconDataStreamSDK_CPP.dylib.
Although I played with it for more than a week from giving linking options to Extension package in setup.py to manipulating @executable_path of the .dylib files, I could not install it.

I wrote a simple Python program to grab coordinates of an object.

I'm doing a continual loop that looks like this:

    while True:
        vicon.get_frame()
        t=vicon.get_segment_global_translation(subject,root_seg_name)
        if t is None:
            continue
        x=t[0]/1000;
        y=t[1]/1000;
        z=t[2]/1000;
        print("X: {0:.6f} Y: {0:.6f} Z: {0:.6f}".format(x,y,z))
        time.sleep(.01)

After running for a period of time the call to get_frame fails with either a segmentation fault or
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

Unfortunately, it appears to be happening in pyvicon.cpp at this line:
out = client->GetFrame();

I suspect this is internal to the Vicon SDK, But I don't know.

UPDATE:
Fixed by changing the client to Pull from PreFetch
