C Specification

To dynamically set the front face orientation, call:

// Provided by VK_VERSION_1_3
void vkCmdSetFrontFace(
    VkCommandBuffer                             commandBuffer,
    VkFrontFace                                 frontFace);

or the equivalent command

// Provided by VK_EXT_extended_dynamic_state
void vkCmdSetFrontFaceEXT(
    VkCommandBuffer                             commandBuffer,
    VkFrontFace                                 frontFace);

Parameters

  • commandBuffer is the command buffer into which the command will be recorded.

  • frontFace is a VkFrontFace value specifying the front-facing triangle orientation to be used for culling.

Description

This command sets the front face orientation for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_FRONT_FACE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineRasterizationStateCreateInfo::frontFace value used to create the currently active pipeline.

Valid Usage (Implicit)
  • VUID-vkCmdSetFrontFace-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdSetFrontFace-frontFace-parameter
    frontFace must be a valid VkFrontFace value

  • VUID-vkCmdSetFrontFace-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdSetFrontFace-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
