pattern VK_DYNAMIC_STATE_SAMPLE_LOCATIONS_EXT :: VkDynamicState

VK_DYNAMIC_STATE_SAMPLE_LOCATIONS_EXT specifies that the sampleLocationsInfo state in VkPipelineSampleLocationsStateCreateInfoEXT will be ignored and must be set dynamically with vkCmdSetSampleLocationsEXT before any draw or clear commands. Enabling custom sample locations is still indicated by the sampleLocationsEnable member of VkPipelineSampleLocationsStateCreateInfoEXT.

The sample locations in pSampleLocations specify sampleLocationsPerPixel number of sample locations for each pixel in the grid of the size specified in sampleLocationGridSize.

data VkPhysicalDeviceSampleLocationsPropertiesEXT

VkPhysicalDeviceSampleLocationsPropertiesEXT - Structure describing sample location limits that can be supported by an implementation

Members

The members of the VkPhysicalDeviceSampleLocationsPropertiesEXT structure describe the following implementation-dependent limits:

Description

• 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.

Valid Usage (Implicit)

• sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SAMPLE_LOCATIONS_PROPERTIES_EXT

If the VkPhysicalDeviceSampleLocationsPropertiesEXT structure is included in the pNext chain of VkPhysicalDeviceProperties2, it is filled with the implementation-dependent limits.
