VkPipelineViewportSwizzleStateCreateInfoNV(3)

Name

VkPipelineViewportSwizzleStateCreateInfoNV - Structure specifying swizzle applied to primitive clip coordinates

C Specification

Each primitive sent to a given viewport has a swizzle and optional negation applied to its clip coordinates. The swizzle that is applied depends on the viewport index, and is controlled by the VkPipelineViewportSwizzleStateCreateInfoNV pipeline state:

// Provided by VK_NV_viewport_swizzle
typedef struct VkPipelineViewportSwizzleStateCreateInfoNV {
    VkStructureType                                sType;
    const void*                                    pNext;
    VkPipelineViewportSwizzleStateCreateFlagsNV    flags;
    uint32_t                                       viewportCount;
    const VkViewportSwizzleNV*                     pViewportSwizzles;
} VkPipelineViewportSwizzleStateCreateInfoNV;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is reserved for future use.

  • viewportCount is the number of viewport swizzles used by the pipeline.

  • pViewportSwizzles is a pointer to an array of VkViewportSwizzleNV structures, defining the viewport swizzles.

Description

Valid Usage

  • VUID-VkPipelineViewportSwizzleStateCreateInfoNV-viewportCount-01215
    viewportCount must be greater than or equal to the viewportCount set in VkPipelineViewportStateCreateInfo

Valid Usage (Implicit)

  • VUID-VkPipelineViewportSwizzleStateCreateInfoNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_PIPELINE_VIEWPORT_SWIZZLE_STATE_CREATE_INFO_NV

  • VUID-VkPipelineViewportSwizzleStateCreateInfoNV-flags-zerobitmask
    flags must be 0

  • VUID-VkPipelineViewportSwizzleStateCreateInfoNV-pViewportSwizzles-parameter
    pViewportSwizzles must be a valid pointer to an array of viewportCount valid VkViewportSwizzleNV structures

  • VUID-VkPipelineViewportSwizzleStateCreateInfoNV-viewportCount-arraylength
    viewportCount must be greater than 0
