vkCmdSetCoverageModulationTableNV
Specify the coverage modulation table dynamically for a command buffer
To dynamically set the
pCoverageModulationTable state, call:
void vkCmdSetCoverageModulationTableNV(
VkCommandBuffer commandBuffer,
uint32_t coverageModulationTableCount,
const float* pCoverageModulationTable);
commandBufferis the command buffer into which the command will be recorded.coverageModulationTableCountspecifies the number of elements inpCoverageModulationTable.pCoverageModulationTablespecifies 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.
