 ![59%20AM](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/2/2bef9bc65e9da7f956db7931c7a9203fd0c101a6.png)

Interesting. They both work, but `createShape(PShape.PATH);` definitely renders a better curve. I wonder why?

Also, I got this warning using `size(512,512, P2D):`

`2018-08-31 10:24:49.119 java[70424:4002899] pid(70424)/euid(502) is calling TIS/TSM in non-main thread environment, ERROR : This is NOT allowed. Please call TIS/TSM in main thread!!!`

What annoys me is that `PShape.PATH` is not mentioned at all in the [createShape()](https://processing.org/reference/createShape_.html) reference.

> One of the following parameters are used as the first parameter: **ELLIPSE** , **RECT** , **ARC** , **TRIANGLE** , **SPHERE** , **BOX** , **QUAD** , or **LINE**.

Thanks again to @jb4x and @WakeMeAtThree
