C Specification

To dynamically set the pCoverageModulationTable state, call:

// Provided by VK_EXT_extended_dynamic_state3 with VK_NV_framebuffer_mixed_samples, VK_EXT_shader_object with VK_NV_framebuffer_mixed_samples
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.

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

  • VUID-vkCmdSetCoverageModulationTableNV-pCoverageModulationTable-parameter
    pCoverageModulationTable must be a valid pointer to an array of coverageModulationTableCount float values

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

  • VUID-vkCmdSetCoverageModulationTableNV-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

  • VUID-vkCmdSetCoverageModulationTableNV-videocoding
    This command must only be called outside of a video coding scope

  • VUID-vkCmdSetCoverageModulationTableNV-coverageModulationTableCount-arraylength
    coverageModulationTableCount must be greater than 0

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
