## Name

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

Loading… please wait.

## C Specification

The range of 3D slices for the created image view can be restricted to a subset of the parent image’s Z range by adding a `VkImageViewSlicedCreateInfoEXT` structure to the `pNext` chain of VkImageViewCreateInfo.

The `VkImageViewSlicedCreateInfoEXT` structure is defined as:

    // Provided by VK_EXT_image_sliced_view_of_3d
    typedef struct VkImageViewSlicedCreateInfoEXT {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           sliceOffset;
        uint32_t           sliceCount;
    } VkImageViewSlicedCreateInfoEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `sliceOffset` is the Z-offset for the first 3D slice accessible to the image view.

- `sliceCount` is the number of 3D slices accessible to the image view.

## Description

When this structure is chained to VkImageViewCreateInfo 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 `VkImageViewSlicedCreateInfoEXT` if it uses a descriptor of type VK_DESCRIPTOR_TYPE_STORAGE_IMAGE. For access using any other descriptor type, the contents of `VkImageViewSlicedCreateInfoEXT` are ignored; instead, `sliceOffset` is treated as being equal to 0, and `sliceCount` is treated as being equal to VK_REMAINING_3D_SLICES_EXT.

Valid Usage

- VUID-VkImageViewSlicedCreateInfoEXT-sliceOffset-07867
  `sliceOffset` must be less than the effective view depth as specified in Image Mip Level Sizing

- VUID-VkImageViewSlicedCreateInfoEXT-sliceCount-07868
  If `sliceCount` is not VK_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

- VUID-VkImageViewSlicedCreateInfoEXT-image-07869
  `image` must have been created with `imageType` equal to VK_IMAGE_TYPE_3D

- VUID-VkImageViewSlicedCreateInfoEXT-viewType-07909
  `viewType` must be VK_IMAGE_VIEW_TYPE_3D

- VUID-VkImageViewSlicedCreateInfoEXT-None-07870
  The image view must reference exactly 1 mip level

- VUID-VkImageViewSlicedCreateInfoEXT-None-07871
  The imageSlicedViewOf3D feature must be enabled

Valid Usage (Implicit)

- VUID-VkImageViewSlicedCreateInfoEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_IMAGE_VIEW_SLICED_CREATE_INFO_EXT
