C Specification

The VkAttachmentSampleLocationsEXT structure is defined as:

// Provided by VK_EXT_sample_locations
typedef struct VkAttachmentSampleLocationsEXT {
    uint32_t                    attachmentIndex;
    VkSampleLocationsInfoEXT    sampleLocationsInfo;
} VkAttachmentSampleLocationsEXT;

Members

  • attachmentIndex is the index of the attachment for which the sample locations state is provided.

  • sampleLocationsInfo is the sample locations state to use for the layout transition of the given attachment from the initial layout of the attachment to the image layout specified for the attachment in the first subpass using it.

Description

If the image referenced by the framebuffer attachment at index attachmentIndex was not created with VK_IMAGE_CREATE_SAMPLE_LOCATIONS_COMPATIBLE_DEPTH_BIT_EXT then the values specified in sampleLocationsInfo are ignored.

Valid Usage

  • VUID-VkAttachmentSampleLocationsEXT-attachmentIndex-01531
    attachmentIndex must be less than the attachmentCount specified in VkRenderPassCreateInfo the render pass specified by VkRenderPassBeginInfo::renderPass was created with

Valid Usage (Implicit)

  • VUID-VkAttachmentSampleLocationsEXT-sampleLocationsInfo-parameter
    sampleLocationsInfo must be a valid VkSampleLocationsInfoEXT structure
