Unity shader stories - Rendering a quad wireframe
Improving our existing wireframe shader, to only render quads. This removes many of the diagonal lines from the mesh you may not want.
We use the technique of longest edge removal from the triangles. This removes the majority of cross diagonals in a mesh that is predominantly made of quads. It isn't perfect, but if this is the effect you require it's much closer than that which renders every triangle.
