vkCmdSetDepthCompareOp

Set depth comparison operator dynamically for a command buffer

To dynamically set the depth compare operator, call:

void vkCmdSetDepthCompareOpEXT(
    VkCommandBuffer commandBuffer,
    VkCompareOp depthCompareOp);
  • commandBuffer is the command buffer into which the command will be recorded.
  • depthCompareOp is a VkCompareOp value specifying the comparison operator used for the Depth Comparison step of the depth test.

This command sets the depth comparison operator for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_DEPTH_COMPARE_OP set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineDepthStencilStateCreateInfo::depthCompareOp value used to create the currently active pipeline.
