Support/Demo for First Person View in pydeck

I really like the MapView and OrbitView, but for things like street navigation, I think FirstPersonView would be more convenient for things like street navigation, especially when combined with point clouds and path layers.

According to the deck.gl documentations:

To render, a FirstPersonView needs to be combined with a viewState object with the following parameters:

• longitude (Number, optional) - longitude of the camera
• latitude (Number, optional) - latitude of the camera
• position (Number[3], optional) - meter offsets of the camera from the lng-lat anchor point. Default [0, 0, 0].
• bearing (Number, optional) - bearing angle in degrees. Default 0 (north).
• pitch (Number, optional) - pitch angle in degrees. Default 0 (horizontal).
• maxPitch (Number, optional) - max pitch angle. Default 90 (down).
• minPitch (Number, optional) - min pitch angle. Default -90 (up).

Naturally, I experimented with the FirstPersonView by slightly changing the official Path Layer demo. This is in a jupyter notebook with the latest pydeck version:

import pydeck as pdk
import pandas as pd
import math

DATA_URL = "https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/bart-lines.json"
df = pd.read_json(DATA_URL)

def hex_to_rgb(h):
    h = h.lstrip("#")
    return tuple(int(h[i : i + 2], 16) for i in (0, 2, 4))

df["color"] = df["color"].apply(hex_to_rgb)

view_state = pdk.ViewState(latitude=37.782556, longitude=-122.3484867)
view = pdk.View('FirstPersonView', controller=True)

layer = pdk.Layer(
    type="PathLayer",
    data=df,
    pickable=True,
    get_color="color",
    width_scale=20,
    width_min_pixels=2,
    get_path="path",
    get_width=5,
)

r = pdk.Deck(layers=[layer], initial_view_state=view_state, views=[view], tooltip={"text": "{name}"})
r.to_html("path_layer.html")

Unfortunately, it did not generate anything:

Looking at the browser output, I also found multiple errors:

Does pydeck expect different inputs compared to deck.gl, or is the first person view restricted to only a few layers?

It works very well, sorry for leaving this issue open!

I open-sourced the app that uses first person view to visualize point clouds. The code is here.

@xhlulu let us know if you have any further questions. It does look like FirstPersonView works.
