# VkPhysicalDeviceTransformFeedbackFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceTransformFeedbackFeaturesEXT - Structure describing transform feedback features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceTransformFeedbackFeaturesEXT` structure is defined as:

    typedef struct VkPhysicalDeviceTransformFeedbackFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           transformFeedback;
        VkBool32           geometryStreams;
    } VkPhysicalDeviceTransformFeedbackFeaturesEXT;

## Members

The members of the `VkPhysicalDeviceTransformFeedbackFeaturesEXT` structure describe the following features:

## Description

- `transformFeedback` indicates whether the implementation supports transform feedback and shader modules can declare the `TransformFeedback` capability.

- `geometryStreams` indicates whether the implementation supports the `GeometryStreams` SPIR-V capability.

If the `VkPhysicalDeviceTransformFeedbackFeaturesEXT` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. `VkPhysicalDeviceTransformFeedbackFeaturesEXT` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TRANSFORM_FEEDBACK_FEATURES_EXT`
