getPhysicalDeviceSupportedFramebufferMixedSamplesCombinationsNV Source #

Arguments

:: forall io. MonadIO io
=> PhysicalDevice	`physicalDevice` is the physical device from which to query the set of combinations.
-> io (Result, "combinations" ::: Vector FramebufferMixedSamplesCombinationNV)

vkGetPhysicalDeviceSupportedFramebufferMixedSamplesCombinationsNV - Query supported sample count combinations

Description

If pCombinations is NULL, then the number of supported combinations for the given physicalDevice is returned in pCombinationCount. Otherwise, pCombinationCount must point to a variable set by the user to the number of elements in the pCombinations array, and on return the variable is overwritten with the number of values actually written to pCombinations. If the value of pCombinationCount is less than the number of combinations supported for the given physicalDevice, at most pCombinationCount values will be written pCombinations and INCOMPLETE will be returned instead of SUCCESS to indicate that not all the supported values were returned.

Valid Usage (Implicit)

physicalDevice must be a valid PhysicalDevice handle

pCombinationCount must be a valid pointer to a uint32_t value
If the value referenced by pCombinationCount is not 0, and pCombinations is not NULL, pCombinations must be a valid pointer to an array of pCombinationCount FramebufferMixedSamplesCombinationNV structures

Return Codes

Success

SUCCESS
INCOMPLETE

Failure

Members

The members of the PhysicalDeviceCoverageReductionModeFeaturesNV structure describe the following features:

Description

If the PhysicalDeviceCoverageReductionModeFeaturesNV structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. PhysicalDeviceCoverageReductionModeFeaturesNV can also be included in the pNext chain of DeviceCreateInfo to enable the feature.

Valid Usage (Implicit)

Description

If this structure is not present, or if the extension is not enabled, the default coverage reduction mode is inferred as follows:

If the VK_NV_framebuffer_mixed_samples extension is enabled, then it is as if the coverageReductionMode is COVERAGE_REDUCTION_MODE_MERGE_NV.
If the VK_AMD_mixed_attachment_samples extension is enabled, then it is as if the coverageReductionMode is COVERAGE_REDUCTION_MODE_TRUNCATE_NV.
If both VK_NV_framebuffer_mixed_samples and VK_AMD_mixed_attachment_samples are enabled, then the default coverage reduction mode is implementation-dependent.

Valid Usage (Implicit)

sType must be STRUCTURE_TYPE_PIPELINE_COVERAGE_REDUCTION_STATE_CREATE_INFO_NV

flags must be 0
coverageReductionMode must be a valid CoverageReductionModeNV value

Description

PipelineCoverageReductionStateCreateFlagsNV is a bitmask type for setting a mask, but is currently reserved for future use.

PhysicalDeviceCoverageReductionModeFeaturesNV
Fields coverageReductionMode :: Bool `coverageReductionMode` indicates whether the implementation supports coverage reduction modes. See Coverage Reduction.

PipelineCoverageReductionStateCreateInfoNV
Fields flags :: PipelineCoverageReductionStateCreateFlagsNV `flags` is reserved for future use. coverageReductionMode :: CoverageReductionModeNV `coverageReductionMode` is a `CoverageReductionModeNV` value controlling how color sample coverage is generated from pixel coverage.

pattern COVERAGE_REDUCTION_MODE_MERGE_NV :: CoverageReductionModeNV	`COVERAGE_REDUCTION_MODE_MERGE_NV` specifies that each color sample will be associated with an implementation-dependent subset of samples in the pixel coverage. If any of those associated samples are covered, the color sample is covered.
pattern COVERAGE_REDUCTION_MODE_TRUNCATE_NV :: CoverageReductionModeNV	`COVERAGE_REDUCTION_MODE_TRUNCATE_NV` specifies that for color samples present in the color attachments, a color sample is covered if the pixel coverage sample with the same sample index i is covered; other pixel coverage samples are discarded.
