# VkPipelineRasterizationStateCreateInfo(3) Manual Page

## Name

VkPipelineRasterizationStateCreateInfo - Structure specifying parameters of a newly created pipeline rasterization state

## C Specification

The `VkPipelineRasterizationStateCreateInfo` structure is defined as:

    typedef struct VkPipelineRasterizationStateCreateInfo {
        VkStructureType                            sType;
        const void*                                pNext;
        VkPipelineRasterizationStateCreateFlags    flags;
        VkBool32                                   depthClampEnable;
        VkBool32                                   rasterizerDiscardEnable;
        VkPolygonMode                              polygonMode;
        VkCullModeFlags                            cullMode;
        VkFrontFace                                frontFace;
        VkBool32                                   depthBiasEnable;
        float                                      depthBiasConstantFactor;
        float                                      depthBiasClamp;
        float                                      depthBiasSlopeFactor;
        float                                      lineWidth;
    } VkPipelineRasterizationStateCreateInfo;

## Members

- `sType` is the type of this structure.

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

- `flags` is reserved for future use.

- `depthClampEnable` controls whether to clamp the fragment’s depth values as described in Depth Test. If the pipeline is not created with VkPipelineRasterizationDepthClipStateCreateInfoEXT present then enabling depth clamp will also disable clipping primitives to the z planes of the frustrum as described in Primitive Clipping. Otherwise depth clipping is controlled by the state set in `VkPipelineRasterizationDepthClipStateCreateInfoEXT`.

- `rasterizerDiscardEnable` controls whether primitives are discarded immediately before the rasterization stage.

- `polygonMode` is the triangle rendering mode. See VkPolygonMode.

- `cullMode` is the triangle facing direction used for primitive culling. See VkCullModeFlagBits.

- `frontFace` is a VkFrontFace value specifying the front-facing triangle orientation to be used for culling.

- `depthBiasEnable` controls whether to bias fragment depth values.

- `depthBiasConstantFactor` is a scalar factor controlling the constant depth value added to each fragment.

- `depthBiasClamp` is the maximum (or minimum) depth bias of a fragment.

- `depthBiasSlopeFactor` is a scalar factor applied to a fragment’s slope in depth bias calculations.

- `lineWidth` is the width of rasterized line segments.

## Description

The application can also add a `VkPipelineRasterizationStateRasterizationOrderAMD` structure to the `pNext` chain of a `VkPipelineRasterizationStateCreateInfo` structure. This structure enables selecting the rasterization order to use when rendering with the corresponding graphics pipeline as described in Rasterization Order.

Valid Usage

- If the depth clamping feature is not enabled, `depthClampEnable` must be `VK_FALSE`

- If the non-solid fill modes feature is not enabled, `polygonMode` must be `VK_POLYGON_MODE_FILL` or `VK_POLYGON_MODE_FILL_RECTANGLE_NV`

- If the `https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#VK_NV_fill_rectangle` extension is not enabled, `polygonMode` must not be `VK_POLYGON_MODE_FILL_RECTANGLE_NV`

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PIPELINE_RASTERIZATION_STATE_CREATE_INFO`

- Each `pNext` member of any structure (including this one) in the `pNext` chain must be either `NULL` or a pointer to a valid instance of VkPipelineRasterizationConservativeStateCreateInfoEXT, VkPipelineRasterizationDepthClipStateCreateInfoEXT, VkPipelineRasterizationLineStateCreateInfoEXT, VkPipelineRasterizationStateRasterizationOrderAMD, or VkPipelineRasterizationStateStreamCreateInfoEXT

- The `sType` value of each struct in the `pNext` chain must be unique

- `flags` must be `0`

- `polygonMode` must be a valid VkPolygonMode value

- `cullMode` must be a valid combination of VkCullModeFlagBits values

- `frontFace` must be a valid VkFrontFace value
