VkDescriptorType - Specifies the type of a descriptor in a descriptor set
Description
DESCRIPTOR_TYPE_SAMPLER
specifies a sampler descriptor.
DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER
specifies a combined image sampler descriptor.DESCRIPTOR_TYPE_SAMPLED_IMAGE
specifies a sampled image descriptor.DESCRIPTOR_TYPE_STORAGE_IMAGE
specifies a storage image descriptor.DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
specifies a uniform texel buffer descriptor.DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER
specifies a storage texel buffer descriptor.DESCRIPTOR_TYPE_UNIFORM_BUFFER
specifies a uniform buffer descriptor.DESCRIPTOR_TYPE_STORAGE_BUFFER
specifies a storage buffer descriptor.DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC
specifies a dynamic uniform buffer descriptor.DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC
specifies a dynamic storage buffer descriptor.DESCRIPTOR_TYPE_INPUT_ATTACHMENT
specifies an input attachment descriptor.DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK
specifies an inline uniform block.DESCRIPTOR_TYPE_MUTABLE_EXT
specifies a descriptor of mutable type.DESCRIPTOR_TYPE_SAMPLE_WEIGHT_IMAGE_QCOM
specifies a sampled weight image descriptor.DESCRIPTOR_TYPE_BLOCK_MATCH_IMAGE_QCOM
specifies a block matching image descriptor.
When a descriptor set is updated via elements of
WriteDescriptorSet
, members of
pImageInfo
, pBufferInfo
and pTexelBufferView
are only accessed by
the implementation when they correspond to descriptor type being defined
- otherwise they are ignored. The members accessed are as follows for
each descriptor type:
- For
DESCRIPTOR_TYPE_SAMPLER
, only thesampler
member of each element ofWriteDescriptorSet
::pImageInfo
is accessed. - For
DESCRIPTOR_TYPE_SAMPLED_IMAGE
,DESCRIPTOR_TYPE_STORAGE_IMAGE
, orDESCRIPTOR_TYPE_INPUT_ATTACHMENT
, only theimageView
andimageLayout
members of each element ofWriteDescriptorSet
::pImageInfo
are accessed. - For
DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER
, all members of each element ofWriteDescriptorSet
::pImageInfo
are accessed. - For
DESCRIPTOR_TYPE_UNIFORM_BUFFER
,DESCRIPTOR_TYPE_STORAGE_BUFFER
,DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC
, orDESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC
, all members of each element ofWriteDescriptorSet
::pBufferInfo
are accessed. - For
DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER
orDESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER
, each element ofWriteDescriptorSet
::pTexelBufferView
is accessed.
When updating descriptors with a descriptorType
of
DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK
, none of the pImageInfo
,
pBufferInfo
, or pTexelBufferView
members are accessed, instead the
source data of the descriptor update operation is taken from the
WriteDescriptorSetInlineUniformBlock
structure in the pNext
chain of
WriteDescriptorSet
. When updating
descriptors with a descriptorType
of
DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR
, none of the pImageInfo
,
pBufferInfo
, or pTexelBufferView
members are accessed, instead the
source data of the descriptor update operation is taken from the
WriteDescriptorSetAccelerationStructureKHR
structure in the pNext
chain of
WriteDescriptorSet
. When updating
descriptors with a descriptorType
of
DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_NV
, none of the pImageInfo
,
pBufferInfo
, or pTexelBufferView
members are accessed, instead the
source data of the descriptor update operation is taken from the
WriteDescriptorSetAccelerationStructureNV
structure in the pNext
chain of
WriteDescriptorSet
.
