# CVOpenGLESTexture A texture-based image buffer that supplies source image data to OpenGL ES. ## Discussion Core Video OpenGL ES textures are texture-based image buffers the system uses to supply source image data to OpenGL. ## Topics ### Inspecting Textures The functions in this section operate on Core Video texture-based image buffers derived from the `CVOpenGLESTextureRef` type. [`func CVOpenGLESTextureGetTarget(CVOpenGLESTexture) -> GLenum`](/documentation/CoreVideo/CVOpenGLESTextureGetTarget(_:)) Returns the texture target for a `CVOpenGLESTextureRef`. [`func CVOpenGLESTextureGetName(CVOpenGLESTexture) -> GLuint`](/documentation/CoreVideo/CVOpenGLESTextureGetName(_:)) Returns the texture target name for a `CVOpenGLESTextureRef`. [`func CVOpenGLESTextureGetCleanTexCoords(CVOpenGLESTexture, UnsafeMutablePointer, UnsafeMutablePointer, UnsafeMutablePointer, UnsafeMutablePointer)`](/documentation/CoreVideo/CVOpenGLESTextureGetCleanTexCoords(_:_:_:_:_:)) Returns convenient normalized texture coordinates for the part of the image that should be displayed. [`func CVOpenGLESTextureIsFlipped(CVOpenGLESTexture) -> Bool`](/documentation/CoreVideo/CVOpenGLESTextureIsFlipped(_:)) Returns whether the image is flipped vertically or not. [`func CVOpenGLESTextureGetTypeID() -> CFTypeID`](/documentation/CoreVideo/CVOpenGLESTextureGetTypeID()) Returns the Core Foundation type identifier for a Core Video texture-based image buffer. ### Data Types [`typealias CVOpenGLESTexture`](/documentation/CoreVideo/CVOpenGLESTexture) A reference to a Core Video texture-based image buffer. --- Copyright © 2026 Apple Inc.
