Enumeration

MTLTextureUsage

The options that determine how a texture will be used.

Declaration

typedef enum MTLTextureUsage : NSUInteger {
    ...
} MTLTextureUsage;

Overview

You can combine multiple usage options if the texture serves multiple uses during its life cycle. The texture can be used only in the ways specified by its usage options; otherwise, an error occurs. Setting appropriate usage options allows Metal to optimize GPU operations for the texture.

Topics

Usage Options

MTLTextureUsageUnknown

An option that specifies that the texture usage is unknown.

MTLTextureUsageShaderRead

An option that enables reading or sampling from the texture.

MTLTextureUsageShaderWrite

An option that enables writing to the texture.

MTLTextureUsageRenderTarget

An option that enables using the texture as a color, depth, or stencil render target in a render pass descriptor.

MTLTextureUsagePixelFormatView

An option that enables using the texture to create texture views.
