VkPhysicalDeviceOpacityMicromapPropertiesKHR(3)

C Specification

The VkPhysicalDeviceOpacityMicromapPropertiesKHR structure is defined as:

// Provided by VK_KHR_opacity_micromap
typedef struct VkPhysicalDeviceOpacityMicromapPropertiesKHR {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           maxOpacity2StateSubdivisionLevel;
    uint32_t           maxOpacity4StateSubdivisionLevel;
    uint32_t           maxOpacityLossy4StateSubdivisionLevel;
    uint64_t           maxMicromapTriangles;
} VkPhysicalDeviceOpacityMicromapPropertiesKHR;

Members

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
maxOpacity2StateSubdivisionLevel is the maximum allowed subdivisionLevel when format is VK_OPACITY_MICROMAP_FORMAT_2_STATE_KHR.
maxOpacity4StateSubdivisionLevel is the maximum allowed subdivisionLevel when format is VK_OPACITY_MICROMAP_FORMAT_4_STATE_KHR and the micromap is not built with VK_BUILD_ACCELERATION_STRUCTURE_MICROMAP_LOSSY_BIT_KHR.
maxOpacityLossy4StateSubdivisionLevel is the maximum allowed subdivisionLevel when format is VK_OPACITY_MICROMAP_FORMAT_4_STATE_KHR and the micromap is built with VK_BUILD_ACCELERATION_STRUCTURE_MICROMAP_LOSSY_BIT_KHR.
maxMicromapTriangles limits the number of triangles allowed to be specified when building a micromap

Description

If the VkPhysicalDeviceOpacityMicromapPropertiesKHR structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

VUID-VkPhysicalDeviceOpacityMicromapPropertiesKHR-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_OPACITY_MICROMAP_PROPERTIES_KHR

Structure Chaining
