public class VkSampleLocationsInfoEXT extends org.lwjgl.system.Struct<VkSampleLocationsInfoEXT> implements org.lwjgl.system.NativeResource
Structure specifying a set of sample locations.
Description

This structure can be used either to specify the sample locations to be used for rendering or to specify the set of sample locations an image subresource has been last rendered with for the purposes of layout transitions of depth/stencil images created with IMAGE_CREATE_SAMPLE_LOCATIONS_COMPATIBLE_DEPTH_BIT_EXT.

The sample locations in pSampleLocations specify sampleLocationsPerPixel number of sample locations for each pixel in the grid of the size specified in sampleLocationGridSize. The sample location for sample i at the pixel grid location (x,y) is taken from pSampleLocations[(x + y × sampleLocationGridSize.width) × sampleLocationsPerPixel + i].

If the render pass has a fragment density map, the implementation will choose the sample locations for the fragment and the contents of pSampleLocations may be ignored.

Valid Usage
  • sampleLocationsPerPixel must be a valid VkSampleCountFlagBits value that is set in VkPhysicalDeviceSampleLocationsPropertiesEXT::sampleLocationSampleCounts
  • sampleLocationsCount must equal sampleLocationsPerPixel × sampleLocationGridSize.width × sampleLocationGridSize.height
Valid Usage (Implicit)
