VkLineRasterizationModeKHR

Line rasterization modes

Possible values of VkPipelineRasterizationLineStateCreateInfoKHR::lineRasterizationMode are:

typedef enum VkLineRasterizationModeKHR {
    VK_LINE_RASTERIZATION_MODE_DEFAULT_KHR = 0,
    VK_LINE_RASTERIZATION_MODE_DEFAULT_EXT = VK_LINE_RASTERIZATION_MODE_DEFAULT_KHR,
    VK_LINE_RASTERIZATION_MODE_RECTANGULAR_KHR = 1,
    VK_LINE_RASTERIZATION_MODE_RECTANGULAR_EXT = VK_LINE_RASTERIZATION_MODE_RECTANGULAR_KHR,
    VK_LINE_RASTERIZATION_MODE_BRESENHAM_KHR = 2,
    VK_LINE_RASTERIZATION_MODE_BRESENHAM_EXT = VK_LINE_RASTERIZATION_MODE_BRESENHAM_KHR,
    VK_LINE_RASTERIZATION_MODE_RECTANGULAR_SMOOTH_KHR = 3,
    VK_LINE_RASTERIZATION_MODE_RECTANGULAR_SMOOTH_EXT = VK_LINE_RASTERIZATION_MODE_RECTANGULAR_SMOOTH_KHR,
} VkLineRasterizationModeKHR;

or the equivalent

#define VkLineRasterizationModeEXT VkLineRasterizationModeKHR
  • VK_LINE_RASTERIZATION_MODE_DEFAULT_KHR is equivalent to VK_LINE_RASTERIZATION_MODE_RECTANGULAR_KHR 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_KHR specifies lines drawn as if they were rectangles extruded from the line
  • VK_LINE_RASTERIZATION_MODE_BRESENHAM_KHR 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_KHR specifies lines drawn if they were rectangles extruded from the line, with alpha falloff, as defined in Smooth Lines.
