## Name

VkPhysicalDeviceLineRasterizationFeatures - Structure describing the line rasterization features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceLineRasterizationFeatures` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDeviceLineRasterizationFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           rectangularLines;
        VkBool32           bresenhamLines;
        VkBool32           smoothLines;
        VkBool32           stippledRectangularLines;
        VkBool32           stippledBresenhamLines;
        VkBool32           stippledSmoothLines;
    } VkPhysicalDeviceLineRasterizationFeatures;

or the equivalent

    // Provided by VK_KHR_line_rasterization
    typedef VkPhysicalDeviceLineRasterizationFeatures VkPhysicalDeviceLineRasterizationFeaturesKHR;

or the equivalent

    // Provided by VK_EXT_line_rasterization
    typedef VkPhysicalDeviceLineRasterizationFeatures VkPhysicalDeviceLineRasterizationFeaturesEXT;

## Members

This structure describes the following features:

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

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

## Description

- `rectangularLines` indicates whether the implementation supports rectangular line rasterization.

- `bresenhamLines` indicates whether the implementation supports Bresenham-style line rasterization.

- `smoothLines` indicates whether the implementation supports smooth line rasterization.

- `stippledRectangularLines` indicates whether the implementation supports stippled line rasterization with `VK_LINE_RASTERIZATION_MODE_RECTANGULAR` lines.

- `stippledBresenhamLines` indicates whether the implementation supports stippled line rasterization with `VK_LINE_RASTERIZATION_MODE_BRESENHAM` lines.

- `stippledSmoothLines` indicates whether the implementation supports stippled line rasterization with `VK_LINE_RASTERIZATION_MODE_RECTANGULAR_SMOOTH` lines.

If the `VkPhysicalDeviceLineRasterizationFeatures` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceLineRasterizationFeatures`, it must add an instance of the structure, with the desired feature members set to `VK_TRUE`, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceLineRasterizationFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_LINE_RASTERIZATION_FEATURES`
