GL.wireframe

설명

Should rendering be done in wireframe?

Turning on wireframe mode will affect all objects rendered after the call, until you turn wireframe back off. In the Unity editor, wireframe mode is always turned off before repainting any window.

Note that some platforms, for example mobile (OpenGL ES) does not support wireframe rendering.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void OnPreRender() {
        GL.wireframe = true;
    }
    void OnPostRender() {
        GL.wireframe = false;
    }
}
