VkCullModeFlagBits(3)

# VkCullModeFlagBits(3) Manual Page

## Name

VkCullModeFlagBits - Bitmask controlling triangle culling

## 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:

    // Provided by VK_VERSION_1_0
    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.
