navigation view receive new input automatically update view

[chongxi]

When parsing the vr stream from multiprocessing pipe. We get time and coord from reading process

The goal is to use just one line of code to update: (Assign time budget 2ms)

1. The current position (Marker)
2. The trajectory (Line)

Property and Setter should be used so that line looks like: nav_view.current_pos = np.array(coord)

The function will look like

def nav_view_update(self):
    ts, coord = self.pipe_gui_side.recv()
    self.nav_view.current_pos = np.array(coord)

Above sample code received input from jovian process which runs in a different CPU continuously.

jovian reading process

def _jovian_process(pipe_jovian_side, jov):
    while True:
        with Timer('', verbose=True):
            _t, _coord = jov.readline().parse()
            pipe_jovian_side.send((_t, _coord))
        print(_t, _coord)

[chongxi]

parsed behavior data is communicate between pipe_gui_side and pipe_jovian_side under 1 ms
