VkImageViewSlicedCreateInfoEXT - Specify the subset of 3D slices of an image view

Description

When this structure is chained to ImageViewCreateInfo the sliceOffset field is treated as a Z-offset for the sliced view and sliceCount specifies the range. Shader accesses using a Z coordinate of 0 will access the depth slice corresponding to sliceOffset in the image, and in a shader, the maximum in-bounds Z coordinate for the view is sliceCount - 1.

A sliced 3D view must only be used with a single mip level. The slice coordinates are integer coordinates within the subresourceRange.baseMipLevel used to create the image view.

The effective view depth is equal to extent.depth used to create the image for this view adjusted by subresourceRange.baseMipLevel as specified in Image Mip Level Sizing.

Shader access to this image view is only affected by ImageViewSlicedCreateInfoEXT if it uses a descriptor of type DESCRIPTOR_TYPE_STORAGE_IMAGE. For access using any other descriptor type, the contents of ImageViewSlicedCreateInfoEXT are ignored; instead, sliceOffset is treated as being equal to 0, and sliceCount is treated as being equal to REMAINING_3D_SLICES_EXT.

Valid Usage

• sliceOffset must be less than the effective view depth as specified in Image Mip Level Sizing

• If sliceCount is not REMAINING_3D_SLICES_EXT, it must be non-zero and sliceOffset + sliceCount must be less than or equal to the effective view depth as specified in Image Mip Level Sizing

• image must have been created with imageType equal to IMAGE_TYPE_3D

• viewType must be IMAGE_VIEW_TYPE_3D

• The image view must reference exactly 1 mip level

• The imageSlicedViewOf3D feature must be enabled

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_IMAGE_VIEW_SLICED_CREATE_INFO_EXT

VkPhysicalDeviceImageSlicedViewOf3DFeaturesEXT - Structure describing whether slice-based views of 3D images can be used in storage image descriptors

Members

The members of the PhysicalDeviceImageSlicedViewOf3DFeaturesEXT structure describe the following features:

Description

If the PhysicalDeviceImageSlicedViewOf3DFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceImageSlicedViewOf3DFeaturesEXT, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
