WebCamTexture+ScreenShotで擬似カメラ

ScreenShot.cs

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System.IO;

public class ScreenShot : MonoBehaviour {
	
	public void Shot(){

		string format = "yyyy-MM-dd-HH-mm-ss"; 
		string fileName =  System.DateTime.Now.ToString (format)+".png";

		//スクリーンショット撮影(保存先はApplication.persistentDataPath直下)
		Application.CaptureScreenshot(fileName);


		string filePath = "";

		// select platform
		switch (Application.platform) {
		case RuntimePlatform.IPhonePlayer:
			filePath = Application.persistentDataPath + "/"+fileName;
			break;
		case RuntimePlatform.Android:
			filePath = Application.persistentDataPath + "/"+fileName;
			break;
		default:
			filePath = fileName;
			break;
		}
		//ファイルの保存を待つ処理
	StartCoroutine (ImageCheck(filePath));
	}
	
	IEnumerator ImageCheck(string _filePath){
		while (File.Exists (_filePath) == false) {
			yield return new WaitForSeconds(0.2f); //
		}
		Debug.Log("OK");;
	}
}

WebCam.cs

using UnityEngine;
using System.Collections;

public class WebCam : MonoBehaviour {
	
	public GameObject Quad;

	public int camWidth_px = 1280;
	public int camHeight_px = 720;

	WebCamTexture webcamTexture;

	void Start () {

		var devices = WebCamTexture.devices;

		if (devices.Length > 0)
		{
			var euler = transform.localRotation.eulerAngles;
			webcamTexture = new WebCamTexture(camWidth_px,camHeight_px);

			//iPhone,Androidの場合はカメラの向きを縦にする
			if(Application.platform == RuntimePlatform.IPhonePlayer||Application.platform == RuntimePlatform.Android){
				transform.localRotation = Quaternion.Euler( euler.x, euler.y, euler.z - 90 );
			}

			renderer.material.mainTexture = webcamTexture;
			webcamTexture.Play();

		}else
		{
			Debug.Log("Webカメラが検出できませんでした");
			return;
		}
	}

	//Sceneを変更する場合にカメラを止める
	public void EndCam(){
		webcamTexture.Stop ();
	}
}
