# VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM(3) Manual Page

## Name

VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM - Structure describing the data graph optical flow features supported by the implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM` structure is defined as:

    // Provided by VK_ARM_data_graph_optical_flow
    typedef struct VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           dataGraphOpticalFlow;
    } VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM;

## Members

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. * `dataGraphOpticalFlow` indicates whether the implementation supports optical flow graph pipelines.

If the `VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM` 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 `VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM`, 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.

## Description

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDataGraphOpticalFlowFeaturesARM-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DATA_GRAPH_OPTICAL_FLOW_FEATURES_ARM
