imageOrientation

image가 screen에 맞춰 정렬되도록 screen을 기준으로 시계 방향으로 회전해야 하는 각도를 계산합니다. screenRotation은 natural orientation을 기준으로 한 screen image의 시계 방향 회전 각도입니다. iOS의 경우: * UIInterfaceOrientationPortrait: screenRotation = 0 * UIInterfaceOrientationLandscapeRight: screenRotation = 90 * UIInterfaceOrientationPortraitUpsideDown: screenRotation = 180 * UIInterfaceOrientationLandscapeLeft: screenRotation = 270 Android의 경우: * Surface.ROTATION_0: screenRotation = 0 * Surface.ROTATION_90: screenRotation = 90 * Surface.ROTATION_180: screenRotation = 180 * Surface.ROTATION_270: screenRotation = 270

imageHorizontalFlip

image에 horizontal flipping이 필요한지 계산합니다. image 렌더링 시 먼저 회전한 다음 flipping합니다. cameraDeviceType이 front camera이면 flipping이 자동으로 수행됩니다. manualHorizontalFlip을 전달하면 그 위에 수동 flipping을 한 번 더 적용할 수 있습니다.

projection

virtual objects를 렌더링하는 데 필요한 perspective projection matrix를 계산하여 camera coordinate system의 점을 clip coordinate system ([-1, 1]^4)으로 변환합니다. z축 주위의 회전도 포함합니다. perspective projection matrix의 형식은 OpenGL과 동일합니다. matrix는 Direct3D처럼 왼쪽에서 곱하지 않고, 점의 동차 좌표 column vector에 오른쪽에서 곱합니다. 데이터는 row-major 순서로 배열되며 OpenGL의 column-major와 반대입니다. clip coordinate system 및 normalized device coordinate system의 정의는 OpenGL 기본값과 동일합니다.
