Is it possible to draw a Mesh or SimplePlane from 8 corner points?

Hey there,

I`m currently working on a perspective transform with pixi. I found the example here: https://pixijs.io/examples/#/plugin-projection/quad-bi.js

Problem: The image is not drawn cleanly on the edge, even when setting antialias: true 

So now i thought about using a mesh or SimplePlane to make the edges smooth (example: https://codepen.io/osublake/pen/gLGYxx)

I only have 8 points to draw the mesh. Is that possible?

What would be the best approach to this?

Thanks
