Ah, I see! Thank you for the explanation!

Going bac…

The same point can be obviously be shared between edges and triangles, but it can only be the same vertex for drawing purposes, with the same UV coordinates, if all the triangles are drawn with the same texture without seams along incident edges. Whenever the UV coordinates on the left and right si…
