VkPhysicalDevicePipelineOpacityMicromapFeaturesARM(3)

# VkPhysicalDevicePipelineOpacityMicromapFeaturesARM(3) Manual Page

## Name

VkPhysicalDevicePipelineOpacityMicromapFeaturesARM - Structure describing features supported by VK_ARM_pipeline_opacity_micromap

## C Specification

The VkPhysicalDevicePipelineOpacityMicromapFeaturesARM structure is defined as:

    // Provided by VK_ARM_pipeline_opacity_micromap
    typedef struct VkPhysicalDevicePipelineOpacityMicromapFeaturesARM {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           pipelineOpacityMicromap;
    } VkPhysicalDevicePipelineOpacityMicromapFeaturesARM;

## Members

This structure describes the following features:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

## Description

- `pipelineOpacityMicromap` indicates if a pipeline can declare if it can be used with an acceleration structure referencing an opacity micromap, or not.

If the `VkPhysicalDevicePipelineOpacityMicromapFeaturesARM` 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 `VkPhysicalDevicePipelineOpacityMicromapFeaturesARM`, 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)

- VUID-VkPhysicalDevicePipelineOpacityMicromapFeaturesARM-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PIPELINE_OPACITY_MICROMAP_FEATURES_ARM

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
