This extension has the same goal as the OpenGL ES GL_OVR_multiview extension. Multiview is a rendering technique originally designed for VR where it is more efficient to record a single set of commands to be executed with slightly different behavior for each “view”.

It includes a concise way to declare a render pass with multiple views, and gives implementations freedom to render the views in the most efficient way possible. This is done with a multiview configuration specified during render pass creation with the VkRenderPassMultiviewCreateInfo passed into VkRenderPassCreateInfo::pNext.

This extension enables the use of the SPV_KHR_multiview shader extension, which adds a new ViewIndex built-in type that allows shaders to control what to do for each view. If using GLSL there is also the GL_EXT_multiview extension that introduces a highp int gl_ViewIndex; built-in variable for vertex, tessellation, geometry, and fragment shaders.

Promotion to Vulkan 1.1

All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
