## Name

VkPipelineViewportWScalingStateCreateInfoNV - Structure specifying parameters of a newly created pipeline viewport W scaling state

Loading… please wait.

## C Specification

The `VkPipelineViewportWScalingStateCreateInfoNV` structure is defined as:

    // Provided by VK_NV_clip_space_w_scaling
    typedef struct VkPipelineViewportWScalingStateCreateInfoNV {
        VkStructureType                sType;
        const void*                    pNext;
        VkBool32                       viewportWScalingEnable;
        uint32_t                       viewportCount;
        const VkViewportWScalingNV*    pViewportWScalings;
    } VkPipelineViewportWScalingStateCreateInfoNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `viewportWScalingEnable` controls whether viewport W scaling is enabled.

- `viewportCount` is the number of viewports used by W scaling, and must match the number of viewports in the pipeline if viewport W scaling is enabled.

- `pViewportWScalings` is a pointer to an array of VkViewportWScalingNV structures defining the W scaling parameters for the corresponding viewports. If the viewport W scaling state is dynamic, this member is ignored.

## Description

Valid Usage (Implicit)

- VUID-VkPipelineViewportWScalingStateCreateInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_VIEWPORT_W_SCALING_STATE_CREATE_INFO_NV`

- VUID-VkPipelineViewportWScalingStateCreateInfoNV-viewportCount-arraylength
  `viewportCount` must be greater than `0`
