C Specification

The VkAttachmentDescription2 structure is defined as:

Warning
 This functionality is superseded by Vulkan Version 1.4. See Legacy Functionality for more information. 
// Provided by VK_VERSION_1_2
typedef struct VkAttachmentDescription2 {
    VkStructureType                 sType;
    const void*                     pNext;
    VkAttachmentDescriptionFlags    flags;
    VkFormat                        format;
    VkSampleCountFlagBits           samples;
    VkAttachmentLoadOp              loadOp;
    VkAttachmentStoreOp             storeOp;
    VkAttachmentLoadOp              stencilLoadOp;
    VkAttachmentStoreOp             stencilStoreOp;
    VkImageLayout                   initialLayout;
    VkImageLayout                   finalLayout;
} VkAttachmentDescription2;
// Provided by VK_KHR_create_renderpass2
// Equivalent to VkAttachmentDescription2
typedef VkAttachmentDescription2 VkAttachmentDescription2KHR;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is a bitmask of VkAttachmentDescriptionFlagBits specifying additional properties of the attachment.

  • format is a VkFormat value specifying the format of the image that will be used for the attachment.

  • samples is a VkSampleCountFlagBits value specifying the number of samples of the image.

  • loadOp is a VkAttachmentLoadOp value specifying how the contents of color and depth components of the attachment are treated at the beginning of the subpass where it is first used.

  • storeOp is a VkAttachmentStoreOp value specifying how the contents of color and depth components of the attachment are treated at the end of the subpass where it is last used.

  • stencilLoadOp is a VkAttachmentLoadOp value specifying how the contents of stencil components of the attachment are treated at the beginning of the subpass where it is first used.

  • stencilStoreOp is a VkAttachmentStoreOp value specifying how the contents of stencil components of the attachment are treated at the end of the last subpass where it is used.

  • initialLayout is the layout the attachment image subresource will be in when a render pass instance begins.

  • finalLayout is the layout the attachment image subresource will be transitioned to when a render pass instance ends.

Description

Parameters defined by this structure with the same name as those in VkAttachmentDescription have the identical effect to those parameters.

If the separateDepthStencilLayouts feature is enabled, and format is a depth/stencil format, initialLayout and finalLayout can be set to a layout that only specifies the layout of the depth aspect.

If the pNext chain includes a VkAttachmentDescriptionStencilLayout structure, then the stencilInitialLayout and stencilFinalLayout members specify the initial and final layouts of the stencil aspect of a depth/stencil format, and initialLayout and finalLayout only apply to the depth aspect. For depth-only formats, the VkAttachmentDescriptionStencilLayout structure is ignored. For stencil-only formats, the initial and final layouts of the stencil aspect are taken from the VkAttachmentDescriptionStencilLayout structure if present, or initialLayout and finalLayout if not present.

If format is a depth/stencil format, and either initialLayout or finalLayout does not specify a layout for the stencil aspect, then the application must specify the initial and final layouts of the stencil aspect by including a VkAttachmentDescriptionStencilLayout structure in the pNext chain.

loadOp and storeOp are ignored for fragment shading rate attachments. No access to the shading rate attachment is performed in loadOp and storeOp. Instead, access to VK_ACCESS_FRAGMENT_SHADING_RATE_ATTACHMENT_READ_BIT_KHR is performed as fragments are rasterized.
