poly and vertex counting at runtime

Question

Hi all,

I'm trying to display at runtime (deployed app runtime) on the GUI the poly and vertex count visible on the camera and i came up with this:

using UnityEngine; using System.Collections;

public class GFXStats : MonoBehaviour { public GameObject[] allObjects; public float totalPoly; public int totalVertex;

 // Use this for initialization
 void Start()
 {
     allObjects = (GameObject[]) GameObject.FindObjectsOfType(typeof(GameObject));
 }

 void OnGUI()
 {
     string display = "polys: " + totalPoly.ToString() + " / vertex: " + totalVertex.ToString();
     Vector2 dimensao = GUI.skin.label.CalcSize(new GUIContent(display));
     GUI.Label(new Rect(Screen.width / 2 - dimensao.x / 2, Screen.height - 30, dimensao.x, 30), display);
 }

 // Update is called once per frame
 void Update()
 {
     float polyCount = 0;
     int vertCount = 0;
     foreach (GameObject obj in allObjects)
     {
         Renderer rend = obj.GetComponent&lt;Renderer&gt;();
         if (rend &amp;&amp; rend.isVisible)
         {
             MeshFilter mf = obj.GetComponent&lt;MeshFilter&gt;();
             if (mf)
             {
                 polyCount += mf.mesh.triangles.Length/3;
                 vertCount += mf.mesh.vertexCount;
             }
         }
     }
     totalPoly = polyCount;
     totalVertex = vertCount;
 }

}

But the code is only counting the meshes totals. I was looking for the rendering totals (reflections, projectors, etc, increase those values) Any idea ?

Thanks in advance!

There is no way to extract these information in the player at least not without installing NVIDIA PerfHUD and checking them there

PerfHUD and similar tools are a great way to benchmark, and they will give you much more info than just a vertex count. http://developer.nvidia.com/object/nvperfhud_home.html

You're aware of the Rendering Statistics Window in the Game View, right? It does all this. It's not available in your built version though, but since you haven't specifically mentioned that you're aware of it, and you also haven't mentioned built vs. editor runtime, I've just got to check!

sure, i'm aware about the stats window in the editor. I was looking to display those info in the deployed app runtime. Sorry, it is really confusing. I'm editing the question. Thanks anyway ;)

I'm also interrested by this answer, and to be more specific, by the number of polygons actually displayed by the graphical card (i.e. including frustum culling)

Blitz3D a directx7 basic metalanguage used in far 2000 that costed 100$ had total vertices and triangles count in 2 simple api call. I can't get why Unity doesn't have such calls.
