VkPipelineViewportWScalingStateCreateInfoNV(3)

# VkPipelineViewportWScalingStateCreateInfoNV(3) Manual Page

## Name

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

## C Specification

The `VkPipelineViewportWScalingStateCreateInfoNV` structure is defined as:

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

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific 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)

- `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_VIEWPORT_W_SCALING_STATE_CREATE_INFO_NV`

- `viewportCount` must be greater than `0`
