# VkPhysicalDeviceLineRasterizationFeaturesEXT(3) Manual Page

## Name

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

## C Specification

The `VkPhysicalDeviceLineRasterizationFeaturesEXT` structure is defined as:

    typedef struct VkPhysicalDeviceLineRasterizationFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           rectangularLines;
        VkBool32           bresenhamLines;
        VkBool32           smoothLines;
        VkBool32           stippledRectangularLines;
        VkBool32           stippledBresenhamLines;
        VkBool32           stippledSmoothLines;
    } VkPhysicalDeviceLineRasterizationFeaturesEXT;

## Members

The members of the `VkPhysicalDeviceLineRasterizationFeaturesEXT` structure describe the following features:

## 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_EXT` lines, or with `VK_LINE_RASTERIZATION_MODE_DEFAULT_EXT` lines if VkPhysicalDeviceLimits::`strictLines` is `VK_TRUE`.

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

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

If the `VkPhysicalDeviceLineRasterizationFeaturesEXT` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. `VkPhysicalDeviceLineRasterizationFeaturesEXT` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable the feature.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_LINE_RASTERIZATION_FEATURES_EXT`
