## Name

VkLineRasterizationModeEXT - Line rasterization modes

Loading… please wait.

## C Specification

Possible values of VkPipelineRasterizationLineStateCreateInfoEXT::`lineRasterizationMode` are:

    // Provided by VK_EXT_line_rasterization
    typedef enum VkLineRasterizationModeEXT {
        VK_LINE_RASTERIZATION_MODE_DEFAULT_EXT = 0,
        VK_LINE_RASTERIZATION_MODE_RECTANGULAR_EXT = 1,
        VK_LINE_RASTERIZATION_MODE_BRESENHAM_EXT = 2,
        VK_LINE_RASTERIZATION_MODE_RECTANGULAR_SMOOTH_EXT = 3,
    } VkLineRasterizationModeEXT;

## Description

- `VK_LINE_RASTERIZATION_MODE_DEFAULT_EXT` is equivalent to `VK_LINE_RASTERIZATION_MODE_RECTANGULAR_EXT` if VkPhysicalDeviceLimits::`strictLines` is `VK_TRUE`, otherwise lines are drawn as non-`strictLines` parallelograms. Both of these modes are defined in Basic Line Segment Rasterization.

- `VK_LINE_RASTERIZATION_MODE_RECTANGULAR_EXT` specifies lines drawn as if they were rectangles extruded from the line

- `VK_LINE_RASTERIZATION_MODE_BRESENHAM_EXT` specifies lines drawn by determining which pixel diamonds the line intersects and exits, as defined in Bresenham Line Segment Rasterization.

- `VK_LINE_RASTERIZATION_MODE_RECTANGULAR_SMOOTH_EXT` specifies lines drawn if they were rectangles extruded from the line, with alpha falloff, as defined in Smooth Lines.
