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);

Parameters

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

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

Description

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.
