# CVMetalTextureCache

A cache used to create and manage Metal texture objects.

## Overview

Overview A Core Video Metal texture cache creates and manages CVMetalTexture textures. You use a CVMetalTextureCache 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.
