Hi, I’ve been looking into [issue #19](https://github.com/p5py/p5/issues/19) lately.  
I think that it might’ve been because [`smooth()`](https://p5js.org/reference/#/p5/smooth) is not implemented in the native [p5py](https://github.com/p5py/p5).

Also, referring to the [progress sheet](https://docs.google.com/spreadsheets/d/1kFdCCZfsZJ1BB84zwK0Q4CP2GZavBVxGdVjhQUG5Hpw/edit#gid=1305185601), I say that the default is left for anti-aliasing.

But then there’s this comment by @abhikpal [https://github.com/p5py/p5/issues/19#issuecomment-350084580](https://github.com/p5py/p5/issues/19#issuecomment-350084580)

what do you think?

I’ve tested this (Linux, non-HiDPI display). I get the same ‘chunky’ edges. It’s an open issue on GitHub, the second-oldest one in the list.

Sounds like something that requires some OpenGL know-how. The manual tessellate alternative seems problematic. It’s waiting for somebody to fix.
