C Specification
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;
Members
The members of the VkPhysicalDeviceSampleLocationsPropertiesEXT
structure describe the following implementation-dependent limits:
Description
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to an extension-specific 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 insampleLocationSampleCounts
. -
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 toVK_TRUE
, the implementation supports variable sample locations in a subpass. If set toVK_FALSE
, then the sample locations must stay constant in each subpass.
If the VkPhysicalDeviceSampleLocationsPropertiesEXT
structure is
included in the pNext
chain of VkPhysicalDeviceProperties2, it
is filled with the implementation-dependent limits.
