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).
