# VkPhysicalDeviceVertexAttributeDivisorFeatures(3) Manual Page

## Name

VkPhysicalDeviceVertexAttributeDivisorFeatures - Structure describing if fetching of vertex attribute may be repeated for instanced rendering

Loading… please wait.

## C Specification

The `VkPhysicalDeviceVertexAttributeDivisorFeatures` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDeviceVertexAttributeDivisorFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           vertexAttributeInstanceRateDivisor;
        VkBool32           vertexAttributeInstanceRateZeroDivisor;
    } VkPhysicalDeviceVertexAttributeDivisorFeatures;

or the equivalent

    // Provided by VK_KHR_vertex_attribute_divisor
    typedef VkPhysicalDeviceVertexAttributeDivisorFeatures VkPhysicalDeviceVertexAttributeDivisorFeaturesKHR;

or the equivalent

    // Provided by VK_EXT_vertex_attribute_divisor
    typedef VkPhysicalDeviceVertexAttributeDivisorFeatures VkPhysicalDeviceVertexAttributeDivisorFeaturesEXT;

## 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

- `vertexAttributeInstanceRateDivisor` specifies whether vertex attribute fetching may be repeated in the case of instanced rendering.

- `vertexAttributeInstanceRateZeroDivisor` specifies whether a zero value for VkVertexInputBindingDivisorDescriptionEXT::`divisor` is supported.

If the `VkPhysicalDeviceVertexAttributeDivisorFeatures` 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. `VkPhysicalDeviceVertexAttributeDivisorFeatures` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceVertexAttributeDivisorFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VERTEX_ATTRIBUTE_DIVISOR_FEATURES`
