## C Specification

The VkSampleLocationEXT structure is defined as:

// Provided by VK_EXT_sample_locations
typedef struct VkSampleLocationEXT {
float    x;
float    y;
} VkSampleLocationEXT;

## Members

• x is the horizontal coordinate of the sample’s location.

• y is the vertical coordinate of the sample’s location.

## Description

The domain space of the sample location coordinates has an upper-left origin within the pixel in framebuffer space.

The values specified in a VkSampleLocationEXT structure are always clamped to the implementation-dependent sample location coordinate range [sampleLocationCoordinateRange[0],sampleLocationCoordinateRange[1]] that can be queried using VkPhysicalDeviceSampleLocationsPropertiesEXT.
