imageOrientation

Hitung sudut rotasi searah jarum jam yang diperlukan gambar untuk sejajar dengan layar. screenRotation adalah sudut rotasi gambar layar relatif terhadap orientasi alami searah jarum jam. Untuk iOS:

UIInterfaceOrientationLandscapeRight: screenRotation = 90
UIInterfaceOrientationPortraitUpsideDown: screenRotation = 180
UIInterfaceOrientationLandscapeLeft: screenRotation = 270 Untuk Android:
Surface.ROTATION_0: screenRotation = 0
Surface.ROTATION_90: screenRotation = 90
Surface.ROTATION_180: screenRotation = 180
Surface.ROTATION_270: screenRotation = 270

projection

Hitung matriks proyeksi perspektif untuk merender objek virtual, mentransformasikan titik dari sistem koordinat kamera ke sistem koordinat klip ([-1, 1]^4) (termasuk rotasi sumbu z). Bentuk matriks sama dengan OpenGL: matriks dikalikan di kanan vektor kolom koordinat homogen titik, bukan seperti Direct3D yang mengalikan di kiri. Namun susunan data adalah row-major, berlawanan dengan column-major OpenGL. Definisi sistem koordinat klip dan sistem koordinat perangkat ternormalisasi sama dengan default OpenGL.
