Show original quads wireframe of 3D model exported from maya

Hi guys, Maya supports quadrilateral faces. I want to display the wireframe of the quadrilateral faces to represent the original structure.
Like sketchfab:

I found this but has no solution.
Can wireframe mode show quads instead of triangles? - Questions - Babylon.js (

Obj format supports quadrilateral faces,maybe I can use it?

any ideas? thank you~

I guess Sketchfab uses an extra file to draw the wireframe, I will try that and update this answer.
