vkCmdSetCoverageModulationTableNV

Specify the coverage modulation table dynamically for a command buffer
primary / secondary
both
graphics
state

To dynamically set the pCoverageModulationTable state, call:

void vkCmdSetCoverageModulationTableNV(
    VkCommandBuffer commandBuffer,
    uint32_t coverageModulationTableCount,
    const float* pCoverageModulationTable);
  • commandBuffer is the command buffer into which the command will be recorded.
  • coverageModulationTableCount specifies the number of elements in pCoverageModulationTable.
  • pCoverageModulationTable specifies the table of modulation factors containing a value for each number of covered samples.

This command sets the table of modulation factors for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_COVERAGE_MODULATION_TABLE_NV set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineCoverageModulationStateCreateInfoNV::coverageModulationTableCount, and VkPipelineCoverageModulationStateCreateInfoNV::pCoverageModulationTable values used to create the currently active pipeline.
