How to draw triangle wireframe on shaded mesh?

[zhutq]

Hi,

I want to draw triangle wireframe on a shaded mesh, to produce the result like:

I have tried two ways, but neither achieves the effect I want.

1. 

material.wireframe = true;

Get perfect wireframe but the shaded surface is gone.

2.

mesh.enableEdgesRendering(10);

This renders both wireframe and shaded surface, but has one problem: the wireframe is not hidden by the shaded surface if I use multiple render groups. (I add another render group to render 3d objects that ignores depth of previous groups, to render something like a x-y-z coordinate.)

How can I render a triangle wireframe on a shaded surface and make it correctly hidden?

Thank you very much!

Hi zhutq,

maybe you can simply clone your object, scale it a bit and display it as wire frame over your original object? http://www.babylonjs-playground.com/#OM44I#1

I see. I will go this way if I can't find any approach to avoid the clone..

Thank you very much!
