Description

This extension enables tighter array and struct packing to be used with uniform buffers.

It modifies the alignment rules for uniform buffers, allowing for tighter packing of arrays and structures. This allows, for example, the std430 layout, as defined in GLSL to be supported in uniform buffers.

Promotion to Vulkan 1.2

All functionality in this extension is included in core Vulkan 1.2, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

New Structures

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

New Enum Constants

• KHR_UNIFORM_BUFFER_STANDARD_LAYOUT_EXTENSION_NAME

• KHR_UNIFORM_BUFFER_STANDARD_LAYOUT_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_UNIFORM_BUFFER_STANDARD_LAYOUT_FEATURES_KHR
