# vkCmdSetCoverageModulationTableNV(3) Manual Page

## Name

vkCmdSetCoverageModulationTableNV - Specify the coverage modulation table dynamically for a command buffer

Loading… please wait.

## 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);

## Parameters

- `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.

## Description

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

- VUID-vkCmdSetCoverageModulationTableNV-None-09423
  At least one of the following must be true:

  - The `extendedDynamicState3CoverageModulationTable` feature is enabled

  - The `shaderObject` feature is enabled

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
