C Specification

To dynamically set the stencil operations, call:

// Provided by VK_EXT_extended_dynamic_state
void vkCmdSetStencilOpEXT(
    VkCommandBuffer                             commandBuffer,
    VkStencilFaceFlags                          faceMask,
    VkStencilOp                                 failOp,
    VkStencilOp                                 passOp,
    VkStencilOp                                 depthFailOp,
    VkCompareOp                                 compareOp);

Parameters

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

  • faceMask is a bitmask of VkStencilFaceFlagBits specifying the set of stencil state for which to update the stencil operation.

  • failOp is a VkStencilOp value specifying the action performed on samples that fail the stencil test.

  • passOp is a VkStencilOp value specifying the action performed on samples that pass both the depth and stencil tests.

  • depthFailOp is a VkStencilOp value specifying the action performed on samples that pass the stencil test and fail the depth test.

  • compareOp is a VkCompareOp value specifying the comparison operator used in the stencil test.

Description

This command sets the state for a given draw when the graphics pipeline is created with VK_DYNAMIC_STATE_STENCIL_OP_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates.
