Research direction

Reproduce the visual-quality difference using the Python bindings in headless and non-headless rendering modes, then trace the headless rendering path for antialiasing configuration. Done means headless output has visual quality comparable to the original rendering, with the behavior verified on a representative visualization.

Description

Thank you for creating this amazing tool!

I've noticed that the visualization quality significantly degrades when using headless rendering mode. I suspect this is due to antialiasing not being applied in headless mode.

Here’s a comparison for reference (left = headless, right = original).

Is there any way to achieve comparable visual quality in headless mode?

For context, I’m using the Python bindings of Polyscope.
