问在Unity3d中将完整的相机视图(16:9)渲染到纹理上

EN

Camera camera = GameObject.Find("Main Camera");
int resWidth = Screen.width;
int resHeight = Screen.height;

RenderTexture rt = new RenderTexture(resWidth, resHeight, 24);
camera.targetTexture = rt; //Create new renderTexture and assign to camera
Texture2D screenShot = new Texture2D(resWidth, resHeight, TextureFormat.RGB24, false); //Create new texture

camera.Render();

RenderTexture.active = rt;
screenShot.ReadPixels(new Rect(0, 0, resWidth, resHeight), 0, 0); //Apply pixels from camera onto Texture2D

camera.targetTexture = null;
RenderTexture.active = null; //Clean
Destroy(rt); //Free memory
