C Specification

To dynamically set the logical operation to apply for blend state:

// Provided by VK_EXT_extended_dynamic_state2
void vkCmdSetLogicOpEXT(
    VkCommandBuffer                             commandBuffer,
    VkLogicOp                                   logicOp);


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

  • logicOp specifies the logical operation to apply for blend state.


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

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

  • VUID-vkCmdSetLogicOpEXT-logicOp-parameter
    logicOp must be a valid VkLogicOp value

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

  • VUID-vkCmdSetLogicOpEXT-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
