shaderRead
An option for reading or sampling from the texture in a shader.
Declaration
static var shaderRead: MTLTextureUsage { get }Discussion
Set this option if you access the given texture with a read() or sample() function in any shader. This option enables the access::read and access::sample attributes for the texture. For more information about texture functions and access attributes, see Metal Shading Language Guide.
If the texture is a read-write texture that you also access with a write() function in the same shader, set the shaderWrite option to enable the access::read_write attribute.
