init(textureType:pixelFormat:width:height:depth:mipmapLevelCount:arrayLength:textureUsage:swizzle:)
Creates a texture descriptor with the specified texture type, pixel format, dimensions, mipmap count, array length, usage flags, and swizzle pattern.
Declaration
init(textureType: MTLTextureType = .type2D, pixelFormat: MTLPixelFormat = .invalid, width: Int = 0, height: Int = 0, depth: Int = 1, mipmapLevelCount: Int = 1, arrayLength: Int = 1, textureUsage: MTLTextureUsage = .unknown, swizzle: MTLTextureSwizzleChannels = .init(red: .red, green: .green, blue: .blue, alpha: .alpha))Parameters
- textureType:
The dimension and arrangement of texture image data. Defaults to
.type2D. - pixelFormat:
The size and bit layout of all pixels in the texture. Defaults to
.invalid. - width:
The width of the texture image for the base mipmap level, in pixels. Defaults to
0. - height:
The height of the texture image for the base mipmap level, in pixels. Defaults to
0. - depth:
The depth of the texture image for the base mipmap level, in pixels. Defaults to
1. - mipmapLevelCount:
The number of mipmap levels for the texture. Defaults to
1. - arrayLength:
The number of array elements for this texture. Defaults to
1. - textureUsage:
The options that determine how the texture can be used. Defaults to
.unknown. - swizzle:
The channel swizzle pattern the GPU applies when sampling the texture. Defaults to identity.
