C Specification

Possible values of the VkPipelineRasterizationStateCreateInfo::polygonMode property of the currently active pipeline, specifying the method of rasterization for polygons, are:

// Provided by VK_VERSION_1_0
typedef enum VkPolygonMode {
    VK_POLYGON_MODE_FILL = 0,
    VK_POLYGON_MODE_LINE = 1,
    VK_POLYGON_MODE_POINT = 2,
} VkPolygonMode;

Description

  • VK_POLYGON_MODE_POINT specifies that polygon vertices are drawn as points.

  • VK_POLYGON_MODE_LINE specifies that polygon edges are drawn as line segments.

  • VK_POLYGON_MODE_FILL specifies that polygons are rendered using the polygon rasterization rules in this section.

These modes affect only the final rasterization of polygons: in particular, a polygon’s vertices are shaded and the polygon is clipped and possibly culled before these modes are applied.

The point size of the final rasterization of polygons when polygon mode is VK_POLYGON_MODE_POINT is implementation-dependent, and the point size may either be PointSize or 1.0.
