demo for OffScreen rendering?

[lfz]

Hi, I really like the offscreen rendering effect. the color, shadow looks really great. And I cannot tune this effect on the online version. Besides, the online version does not have the auto-rotate function.

I am wondering how to

1. achieve the same rendering effect
2. achieve the auto-rotate function

thank you !

Hi @lfz !

Can you provide example? I'm not sure about what auto-rotate function and rendering are you talking. Please share some code or screens to clarify that. Thanks!

I used offscreen rendering aka headless browser: https://github.com/K3D-tools/K3D-jupyter/blob/main/examples/headless.ipynb

K3D have no auto-rotate function but that is feature that we can discuss. But we can animate camera: https://github.com/K3D-tools/K3D-jupyter/blob/main/examples/Camera_interactive_demo.ipynb

Hi, I had some issues with running the headless.ipynb example, but managed to resolve them on my own.

I was getting the error AttributeError: 'NoneType' object has no attribute 'split' I needed to modify get_headless_driver as ChromeDriverManager().install() was giving me the error.

Following Stackoverflow comment from JeffC, he pointed out: "as of Selenium 4.6+, Selenium now has a driver manager built in so you no longer need ChromeDriverManager()"

The new working code looks like this:

def get_headless_driver(no_headless=False):
    from selenium import webdriver

    options = webdriver.ChromeOptions()

    options.add_argument("--no-sandbox")
    options.add_argument("--disable-crash-reporter")

    if not no_headless:
        options.add_argument("--headless")

    return webdriver.Chrome(options=options)

Result/Output:

@GregorKobsik great sugesstion. I will change a code after testing. Thanks!
