createBufferView

Arguments

:: forall io. MonadIO io

=> Device

device is the logical device that creates the buffer view.

-> BufferViewCreateInfo

pCreateInfo is a pointer to a BufferViewCreateInfo structure containing parameters to be used to create the buffer.

-> ("allocator" ::: Maybe AllocationCallbacks)

pAllocator controls host memory allocation as described in the Memory Allocation chapter.

-> io BufferView

vkCreateBufferView - Create a new buffer view object

Valid Usage (Implicit)

• device must be a valid Device handle

• pCreateInfo must be a valid pointer to a valid BufferViewCreateInfo structure
• If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
• pView must be a valid pointer to a BufferView handle

Return Codes

Success

• SUCCESS

Failure

• ERROR_OUT_OF_HOST_MEMORY
• ERROR_OUT_OF_DEVICE_MEMORY

withBufferView :: forall io r. MonadIO io => Device -> BufferViewCreateInfo -> Maybe AllocationCallbacks -> (io BufferView -> (BufferView -> io ()) -> r) -> r

A convenience wrapper to make a compatible pair of calls to createBufferView and destroyBufferView

To ensure that destroyBufferView is always called: pass bracket (or the allocate function from your favourite resource management library) as the first argument. To just extract the pair pass (,) as the first argument.

destroyBufferView

Arguments

:: forall io. MonadIO io

=> Device

device is the logical device that destroys the buffer view.

-> BufferView

bufferView is the buffer view to destroy.

-> ("allocator" ::: Maybe AllocationCallbacks)

pAllocator controls host memory allocation as described in the Memory Allocation chapter.

-> io ()

vkDestroyBufferView - Destroy a buffer view object

Valid Usage

• All submitted commands that refer to bufferView must have completed execution

• If AllocationCallbacks were provided when bufferView was created, a compatible set of callbacks must be provided here
• If no AllocationCallbacks were provided when bufferView was created, pAllocator must be NULL

Valid Usage (Implicit)

• device must be a valid Device handle

• If bufferView is not NULL_HANDLE, bufferView must be a valid BufferView handle
• If pAllocator is not NULL, pAllocator must be a valid pointer to a valid AllocationCallbacks structure
• If bufferView is a valid handle, it must have been created, allocated, or retrieved from device

Host Synchronization

• Host access to bufferView must be externally synchronized

data BufferViewCreateInfo

VkBufferViewCreateInfo - Structure specifying parameters of a newly created buffer view

Valid Usage

• offset must be less than the size of buffer

• If range is not equal to WHOLE_SIZE, range must be greater than 0
• If range is not equal to WHOLE_SIZE, range must be an integer multiple of the texel block size of format
• If range is not equal to WHOLE_SIZE, range divided by the texel block size of format, multiplied by the number of texels per texel block for that format (as defined in the Compatible Formats table), must be less than or equal to PhysicalDeviceLimits::maxTexelBufferElements
• If range is not equal to WHOLE_SIZE, the sum of offset and range must be less than or equal to the size of buffer
• buffer must have been created with a usage value containing at least one of BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT or BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT
• If buffer was created with usage containing BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT, format must be supported for uniform texel buffers, as specified by the FORMAT_FEATURE_UNIFORM_TEXEL_BUFFER_BIT flag in FormatProperties::bufferFeatures returned by getPhysicalDeviceFormatProperties
• If buffer was created with usage containing BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT, format must be supported for storage texel buffers, as specified by the FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_BIT flag in FormatProperties::bufferFeatures returned by getPhysicalDeviceFormatProperties
• If buffer is non-sparse then it must be bound completely and contiguously to a single DeviceMemory object
• If the texelBufferAlignment feature is not enabled, offset must be a multiple of PhysicalDeviceLimits::minTexelBufferOffsetAlignment
• If the texelBufferAlignment feature is enabled and if buffer was created with usage containing BUFFER_USAGE_STORAGE_TEXEL_BUFFER_BIT, offset must be a multiple of the lesser of PhysicalDeviceTexelBufferAlignmentPropertiesEXT::storageTexelBufferOffsetAlignmentBytes or, if PhysicalDeviceTexelBufferAlignmentPropertiesEXT::storageTexelBufferOffsetSingleTexelAlignment is TRUE, the size of a texel of the requested format. If the size of a texel is a multiple of three bytes, then the size of a single component of format is used instead
• If the texelBufferAlignment feature is enabled and if buffer was created with usage containing BUFFER_USAGE_UNIFORM_TEXEL_BUFFER_BIT, offset must be a multiple of the lesser of PhysicalDeviceTexelBufferAlignmentPropertiesEXT::uniformTexelBufferOffsetAlignmentBytes or, if PhysicalDeviceTexelBufferAlignmentPropertiesEXT::uniformTexelBufferOffsetSingleTexelAlignment is TRUE, the size of a texel of the requested format. If the size of a texel is a multiple of three bytes, then the size of a single component of format is used instead

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_BUFFER_VIEW_CREATE_INFO

• pNext must be NULL
• flags must be 0
• buffer must be a valid Buffer handle
• format must be a valid Format value

Constructors

BufferViewCreateInfo

Fields

• flags :: BufferViewCreateFlags

  flags is reserved for future use.

• buffer :: Buffer

  buffer is a Buffer on which the view will be created.

• format :: Format

  format is a Format describing the format of the data elements in the buffer.

• offset :: DeviceSize

  offset is an offset in bytes from the base address of the buffer. Accesses to the buffer view from shaders use addressing that is relative to this starting offset.

• range :: DeviceSize

  range is a size in bytes of the buffer view. If range is equal to WHOLE_SIZE, the range from offset to the end of the buffer is used. If WHOLE_SIZE is used and the remaining size of the buffer is not a multiple of the texel block size of format, the nearest smaller multiple is used.
