## Name

VkPhysicalDeviceShaderTileImagePropertiesEXT - Structure containing information about tile image support for a physical device

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderTileImagePropertiesEXT` structure is defined as:

    // Provided by VK_EXT_shader_tile_image
    typedef struct VkPhysicalDeviceShaderTileImagePropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderTileImageCoherentReadAccelerated;
        VkBool32           shaderTileImageReadSampleFromPixelRateInvocation;
        VkBool32           shaderTileImageReadFromHelperInvocation;
    } VkPhysicalDeviceShaderTileImagePropertiesEXT;

## Members

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

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

- `shaderTileImageCoherentReadAccelerated` is a boolean that will be `VK_TRUE` if coherent reads of tile image data is accelerated.

- `shaderTileImageReadSampleFromPixelRateInvocation` is a boolean that will be `VK_TRUE` if reading from samples from a pixel rate fragment invocation is supported when VkPipelineMultisampleStateCreateInfo::`rasterizationSamples` > 1.

- `shaderTileImageReadFromHelperInvocation` is a boolean that will be `VK_TRUE` if reads of tile image data from helper fragment invocations result in valid values.

## Description

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

These are properties of the tile image information of a physical device.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceShaderTileImagePropertiesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_TILE_IMAGE_PROPERTIES_EXT`
