Would be cool to use this feature to enable more performance friendly triangles. Currently often thin and long triangles are generated which are not good for rendering performance. Having a few additional vertices within the sprite shape that the boundary vertices can connect to could help with that. Also where can i buy this good sir a coffe/beer for providing this amazing addon free of charge ? <3

@PolyTimotheos
When I first created this library, I used Poly2tri for triangulation.
It made triangles with good performance then other libraries.
But I found that Poly2tri sometimes causes errors.
So I changed triangulation library to LibTessDotNet.

Here is good examples about triangulation.

I want to add the feature for the user to swap triangulation library to Poly2tri.
However, the priority of this task is low.

But I found that Poly2tri sometimes causes errors.

Curious what the errors are. Are they Exceptions or improper tessellation?

[sr4dev]

@heshuimu Both. But I don't remember what exception was...

[sr4dev]

I have no much time.
I gave up on adding a new feature.

I'd love to pick this up if you're interested. Out of curiosity, do you still have the binding layer you used to interface with poly2tri?

[sr4dev]

Regrettably, there is no longer any code related to Poly2Tri. The commit log of this project was too messy, so I recently squashed all the commits. 😭

No problem!
