# VkPhysicalDeviceDescriptorBufferDensityMapPropertiesEXT(3) Manual Page

## Name

VkPhysicalDeviceDescriptorBufferDensityMapPropertiesEXT - Structure describing descriptor buffer density map properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDescriptorBufferDensityMapPropertiesEXT` structure is defined as:

    // Provided by VK_EXT_descriptor_buffer
    typedef struct VkPhysicalDeviceDescriptorBufferDensityMapPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        size_t             combinedImageSamplerDensityMapDescriptorSize;
    } VkPhysicalDeviceDescriptorBufferDensityMapPropertiesEXT;

## Members

- `sType` is the type of this structure.

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

- `combinedImageSamplerDensityMapDescriptorSize` indicates the size in bytes of a `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER` descriptor when creating the descriptor with `VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT` set.

## Description

If the `VkPhysicalDeviceDescriptorBufferDensityMapPropertiesEXT` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDescriptorBufferDensityMapPropertiesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DESCRIPTOR_BUFFER_DENSITY_MAP_PROPERTIES_EXT`
