VkPhysicalDeviceOpacityMicromapFeaturesEXT

Structure describing the ray tracing opacity micromap features that can be supported by an implementation

The VkPhysicalDeviceOpacityMicromapFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceOpacityMicromapFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 micromap;
    VkBool32 micromapCaptureReplay;
    VkBool32 micromapHostCommands;
} VkPhysicalDeviceOpacityMicromapFeaturesEXT;

This structure describes the following feature:

  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • micromap indicates whether the implementation supports the micromap array feature.
  • micromapCaptureReplay indicates whether the implementation supports capture and replay of addresses for micromap arrays.
  • micromapHostCommands indicates whether the implementation supports host side micromap array commands.

If the VkPhysicalDeviceOpacityMicromapFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceOpacityMicromapFeaturesEXT, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)
