# CVMetalTextureCache A cache used to create and manage Metal texture objects. ## Discussion A Core Video Metal texture cache creates and manages [`CVMetalTexture`](/documentation/CoreVideo/CVMetalTexture) textures. You use a [CVMetalTextureCache](/documentation/CoreVideo/cvmetaltexturecache-q3j) object to directly read from or write to GPU-based Core Video image buffers in rendering, or for sharing data with Metal kernels. For example, you can use a Metal texture cache to present live output from a device’s camera in a 3D scene rendered with Metal. ## Topics ### Functions [`CVMetalTextureCacheCreate(_:_:_:_:_:)`](/documentation/CoreVideo/CVMetalTextureCacheCreate(_:_:_:_:_:)) Creates a new texture cache. [`CVMetalTextureCacheCreateTextureFromImage(_:_:_:_:_:_:_:_:_:)`](/documentation/CoreVideo/CVMetalTextureCacheCreateTextureFromImage(_:_:_:_:_:_:_:_:_:)) Creates a Core Video Metal texture buffer from an existing image buffer. [`CVMetalTextureCacheFlush(_:_:)`](/documentation/CoreVideo/CVMetalTextureCacheFlush(_:_:)) Manually flushes the contents of the provided texture cache. [`CVMetalTextureCacheGetTypeID()`](/documentation/CoreVideo/CVMetalTextureCacheGetTypeID()) Returns the Core Foundation type identifier for a Core Video Metal texture cache. ### Data Types [`CVMetalTextureCache`](/documentation/CoreVideo/CVMetalTextureCache) A reference to a Core Video Metal texture cache. ### Constants [Cache Attributes](/documentation/CoreVideo/CVMetalTextureCache-cache-attributes) Attributes specifying texture cache behavior, used with the [`CVMetalTextureCacheCreate(_:_:_:_:_:)`](/documentation/CoreVideo/CVMetalTextureCacheCreate(_:_:_:_:_:)) function. ### Related Documentation --- Copyright © 2026 Apple Inc.
