VkPhysicalDeviceSampleLocationsPropertiesEXT

The VkPhysicalDeviceSampleLocationsPropertiesEXT structure is defined as:

typedef struct VkPhysicalDeviceSampleLocationsPropertiesEXT {
    VkStructureType sType;
    void* pNext;
    VkSampleCountFlags sampleLocationSampleCounts;
    VkExtent2D maxSampleLocationGridSize;
    float sampleLocationCoordinateRange[2];
    uint32_t sampleLocationSubPixelBits;
    VkBool32 variableSampleLocations;
} VkPhysicalDeviceSampleLocationsPropertiesEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• sampleLocationSampleCounts is a bitmask of VkSampleCountFlagBits indicating the sample counts supporting custom sample locations.
• maxSampleLocationGridSize is the maximum size of the pixel grid in which sample locations can vary that is supported for all sample counts in sampleLocationSampleCounts.
• sampleLocationCoordinateRange[2] is the range of supported sample location coordinates.
• sampleLocationSubPixelBits is the number of bits of subpixel precision for sample locations.
• variableSampleLocations specifies whether the sample locations used by all pipelines that will be bound to a command buffer during a subpass must match. If set to VK_TRUE, the implementation supports variable sample locations in a subpass. If set to VK_FALSE, then the sample locations must stay constant in each subpass.

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