# VkCoarseSampleOrderTypeNV(3) Manual Page

## Name

VkCoarseSampleOrderTypeNV - Shading rate image sample ordering types

Loading… please wait.

## C Specification

The type VkCoarseSampleOrderTypeNV specifies the technique used to order coverage samples in fragments larger than one pixel, and is defined as:

    // Provided by VK_NV_shading_rate_image
    typedef enum VkCoarseSampleOrderTypeNV {
        VK_COARSE_SAMPLE_ORDER_TYPE_DEFAULT_NV = 0,
        VK_COARSE_SAMPLE_ORDER_TYPE_CUSTOM_NV = 1,
        VK_COARSE_SAMPLE_ORDER_TYPE_PIXEL_MAJOR_NV = 2,
        VK_COARSE_SAMPLE_ORDER_TYPE_SAMPLE_MAJOR_NV = 3,
    } VkCoarseSampleOrderTypeNV;

## Description

- VK_COARSE_SAMPLE_ORDER_TYPE_DEFAULT_NV specifies that coverage samples will be ordered in an implementation-dependent manner.

- VK_COARSE_SAMPLE_ORDER_TYPE_CUSTOM_NV specifies that coverage samples will be ordered according to the array of custom orderings provided in either the `pCustomSampleOrders` member of `VkPipelineViewportCoarseSampleOrderStateCreateInfoNV` or the `pCustomSampleOrders` member of vkCmdSetCoarseSampleOrderNV.

- VK_COARSE_SAMPLE_ORDER_TYPE_PIXEL_MAJOR_NV specifies that coverage samples will be ordered sequentially, sorted first by pixel coordinate (in row-major order) and then by sample index.

- VK_COARSE_SAMPLE_ORDER_TYPE_SAMPLE_MAJOR_NV specifies that coverage samples will be ordered sequentially, sorted first by sample index and then by pixel coordinate (in row-major order).
