vkCmdSetCoverageReductionModeNV

Specify the coverage reduction mode dynamically for a command buffer
primary / secondary
both
graphics
state

To dynamically set the coverageReductionMode state, call:

void vkCmdSetCoverageReductionModeNV(
    VkCommandBuffer commandBuffer,
    VkCoverageReductionModeNV coverageReductionMode);
  • commandBuffer is the command buffer into which the command will be recorded.
  • coverageReductionMode specifies the coverageReductionMode state.

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