C Specification

Once the orientation of triangles is determined, they are culled according to the VkPipelineRasterizationStateCreateInfo::cullMode property of the currently active pipeline. Possible values are:

typedef enum VkCullModeFlagBits {
    VK_CULL_MODE_NONE = 0,
    VK_CULL_MODE_FRONT_BIT = 0x00000001,
    VK_CULL_MODE_BACK_BIT = 0x00000002,
    VK_CULL_MODE_FRONT_AND_BACK = 0x00000003,
} VkCullModeFlagBits;

Description

  • VK_CULL_MODE_NONE specifies that no triangles are discarded

  • VK_CULL_MODE_FRONT_BIT specifies that front-facing triangles are discarded

  • VK_CULL_MODE_BACK_BIT specifies that back-facing triangles are discarded

  • VK_CULL_MODE_FRONT_AND_BACK specifies that all triangles are discarded.

Following culling, fragments are produced for any triangles which have not been discarded.
