vkCmdSetLogicOpEXT(3)

C Specification

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

// 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 logical operation for blend state for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_LOGIC_OP_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineColorBlendStateCreateInfo::logicOp value used to create the currently active pipeline.
