C Specification

Possible values of the VkViewportSwizzleNV::x, y, z, and w members, specifying swizzling of the corresponding components of primitives, are:

// Provided by VK_NV_viewport_swizzle
typedef enum VkViewportCoordinateSwizzleNV {
    VK_VIEWPORT_COORDINATE_SWIZZLE_POSITIVE_X_NV = 0,
    VK_VIEWPORT_COORDINATE_SWIZZLE_NEGATIVE_X_NV = 1,
    VK_VIEWPORT_COORDINATE_SWIZZLE_POSITIVE_Y_NV = 2,
    VK_VIEWPORT_COORDINATE_SWIZZLE_NEGATIVE_Y_NV = 3,
    VK_VIEWPORT_COORDINATE_SWIZZLE_POSITIVE_Z_NV = 4,
    VK_VIEWPORT_COORDINATE_SWIZZLE_NEGATIVE_Z_NV = 5,
    VK_VIEWPORT_COORDINATE_SWIZZLE_POSITIVE_W_NV = 6,
    VK_VIEWPORT_COORDINATE_SWIZZLE_NEGATIVE_W_NV = 7,
} VkViewportCoordinateSwizzleNV;

Description

These values are described in detail in Viewport Swizzle.
