vkCmdSetCoverageModulationTableNV(3)

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.
