Documentation

data PhysicalDeviceFragmentDensityMap2FeaturesEXT Source #

VkPhysicalDeviceFragmentDensityMap2FeaturesEXT - Structure describing additional fragment density map features that can be supported by an implementation

Members

The members of the PhysicalDeviceFragmentDensityMap2FeaturesEXT structure describe the following features:

Description

If the PhysicalDeviceFragmentDensityMap2FeaturesEXT structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. PhysicalDeviceFragmentDensityMap2FeaturesEXT can also be included in pNext chain of DeviceCreateInfo to enable the features.

Valid Usage (Implicit)

PhysicalDeviceFragmentDensityMap2FeaturesEXT
Fields fragmentDensityMapDeferred :: Bool `fragmentDensityMapDeferred` specifies whether the implementation supports deferred reads of fragment density map image views. If this feature is not enabled, `IMAGE_VIEW_CREATE_FRAGMENT_DENSITY_MAP_DEFERRED_BIT_EXT` must not be included in `ImageViewCreateInfo`::`flags`.

VkPhysicalDeviceFragmentDensityMap2PropertiesEXT - Structure describing additional fragment density map properties that can be supported by an implementation

Members

The members of the PhysicalDeviceFragmentDensityMap2PropertiesEXT structure describe the following implementation-dependent limits:

Valid Usage (Implicit)

If the PhysicalDeviceFragmentDensityMap2PropertiesEXT structure is included in the pNext chain of PhysicalDeviceProperties2, it is filled with the implementation-dependent limits and properties.

subsampledLoads :: Bool
subsampledLoads specifies if performing image data read with load operations on subsampled attachments will be resampled to the fragment density of the render pass
subsampledCoarseReconstructionEarlyAccess :: Bool
subsampledCoarseReconstructionEarlyAccess specifies if performing image data read with samplers created with flags containing SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT in fragment shader will trigger additional reads during PIPELINE_STAGE_VERTEX_SHADER_BIT
maxSubsampledArrayLayers :: Word32
maxSubsampledArrayLayers is the maximum number of ImageView array layers for usages supporting subsampled samplers
maxDescriptorSetSubsampledSamplers :: Word32
maxDescriptorSetSubsampledSamplers is the maximum number of subsampled samplers that can be included in a PipelineLayout
