Description

This extension is based on the VK_EXT_vertex_attribute_divisor extension. The only difference is the new property supportsNonZeroFirstInstance, which indicates support for non-zero values in firstInstance. This allows the extension to be supported on implementations that have traditionally only supported OpenGL ES.

New Structures

• VkVertexInputBindingDivisorDescriptionKHR
• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
  • VkPhysicalDeviceVertexAttributeDivisorFeaturesKHR
• Extending VkPhysicalDeviceProperties2:
  • VkPhysicalDeviceVertexAttributeDivisorPropertiesKHR
• Extending VkPipelineVertexInputStateCreateInfo:
  • VkPipelineVertexInputDivisorStateCreateInfoKHR

New Enum Constants

• VK_KHR_VERTEX_ATTRIBUTE_DIVISOR_EXTENSION_NAME
• VK_KHR_VERTEX_ATTRIBUTE_DIVISOR_SPEC_VERSION
• Extending VkStructureType:
  • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VERTEX_ATTRIBUTE_DIVISOR_FEATURES_KHR
  • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VERTEX_ATTRIBUTE_DIVISOR_PROPERTIES_KHR
  • VK_STRUCTURE_TYPE_PIPELINE_VERTEX_INPUT_DIVISOR_STATE_CREATE_INFO_KHR

Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4 with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
