IPD to pixels

Hey guys,

I'm working on a static class that can be called instead of the static GUI methods.

using UnityEngine;
using System.Collections;

public static class StereoGUI 
{
	public static void DrawTexture(Rect position, Texture image, ScaleMode scaleMode = ScaleMode.StretchToFill, bool alphaBlend = true, float imageAspect = 0)
	{
		if(GameManager.VREnabled())
		{
			Rect leftPosition = new Rect(position.x/2, position.y, position.width/2, position.height);
			Rect rightPosition = new Rect(position.x+(Screen.width/2), position.y, position.width/1.5F, position.height);
			
			GUI.DrawTexture(leftPosition, image, scaleMode, alphaBlend, imageAspect);
			GUI.DrawTexture(rightPosition, image, scaleMode, alphaBlend, imageAspect);
		}
		else
			GUI.DrawTexture(position, image, scaleMode, alphaBlend, imageAspect);
	}
}

The idea is that instead of calling GUI.DrawTexture() you call StereoGUI.DrawTexture() instead and it will draw in stereo or revert based on GameManager.VREnabled()

Usage example:

private void OnGUI()
{
     //GUI.DrawTexture(params); we're replacing this with the new static class below
     StereoGUI.DrawTexture(params);
}

We go about our day writing our DrawTexture calls as if we're making a 2d game and the static class handles the rest.
Now my question comes in where I'd like to use IPD to make the stereo separation more accurate. But to do that, I would need to know precisely what the IPD is in pixels relative to my resolution.

Does anyone know where to get this information?

Thanks!
