## Name

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

Loading… please wait.

## C Specification

The `VkPhysicalDeviceTransformFeedbackFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_transform_feedback
    typedef struct VkPhysicalDeviceTransformFeedbackFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           transformFeedback;
        VkBool32           geometryStreams;
    } VkPhysicalDeviceTransformFeedbackFeaturesEXT;

## Members

This structure describes the following features:

## Description

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

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

- `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 the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. `VkPhysicalDeviceTransformFeedbackFeaturesEXT` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceTransformFeedbackFeaturesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TRANSFORM_FEEDBACK_FEATURES_EXT`
