public class PhotoCapture : IDisposable
Demonstrates how to take a photo using the PhotoCapture functionality and display it on a Unity GameObject.
Examples
using UnityEngine;using System.Collections;using System.Linq;using UnityEngine.Windows.WebCam;public class PhotoCaptureExample : MonoBehaviour{ PhotoCapture photoCaptureObject = null; Texture2D targetTexture = null; // Use this for initialization void Start() { Resolution cameraResolution = PhotoCapture.SupportedResolutions.OrderByDescending((res) => res.width * res.height).First(); targetTexture = new Texture2D(cameraResolution.width, cameraResolution.height); // Create a PhotoCapture object PhotoCapture.CreateAsync(false, delegate(PhotoCapture captureObject) { photoCaptureObject = captureObject; CameraParameters cameraParameters = new CameraParameters(); cameraParameters.hologramOpacity = 0.0f; cameraParameters.cameraResolutionWidth = cameraResolution.width; cameraParameters.cameraResolutionHeight = cameraResolution.height; cameraParameters.pixelFormat = CapturePixelFormat.BGRA32; // Activate the camera photoCaptureObject.StartPhotoModeAsync(cameraParameters, delegate(PhotoCapture.PhotoCaptureResult result) { // Take a picture photoCaptureObject.TakePhotoAsync(OnCapturedPhotoToMemory); }); }); } void OnCapturedPhotoToMemory(PhotoCapture.PhotoCaptureResult result, PhotoCaptureFrame photoCaptureFrame) { // Copy the raw image data into our target texture photoCaptureFrame.UploadImageDataToTexture(targetTexture); // Create a gameobject that we can apply our texture to GameObject quad = GameObject.CreatePrimitive(PrimitiveType.Quad); Renderer quadRenderer = quad.GetComponent<Renderer>() as Renderer; quadRenderer.material = new Material(Shader.Find("Unlit/Texture")); quad.transform.parent = this.transform; quad.transform.localPosition = new Vector3(0.0f, 0.0f, 3.0f); quadRenderer.material.SetTexture("_MainTex", targetTexture); // Deactivate our camera photoCaptureObject.StopPhotoModeAsync(OnStoppedPhotoMode); } void OnStoppedPhotoMode(PhotoCapture.PhotoCaptureResult result) { // Shutdown our photo capture resource photoCaptureObject.Dispose(); photoCaptureObject = null; }}
