Parties desiring to implement the Specification and make use of Khronos trademarks in relation to that implementation, and receive reciprocal patent license protection under the Khronos Intellectual Property Rights Policy must become Adopters and confirm the implementation as conformant under the process defined by Khronos for this Specification; see https://www.khronos.org/adopters. endif::ratified_core_spec[] // Specifications that include non-ratified extensions ifndef::ratified_core_spec[] ifndef::VKSC_VERSION_1_0[] :apinameCR: Vulkan :apiUrlCore: https://registry.khronos.org/vulkan/specs/1.3/html/vkspec.html :apiUrlKHR: https://registry.khronos.org/vulkan/specs/1.3-khr-extensions/html/vkspec.html endif::VKSC_VERSION_1_0[] ifdef::VKSC_VERSION_1_0[] :apinameCR: Vulkan SC :apiUrlCore: https://registry.khronos.org/vulkansc/specs/1.0/html/vkspec.html :apiUrlKHR: https://registry.khronos.org/vulkansc/specs/1.0-khr-extensions/html/vkspec.html endif::VKSC_VERSION_1_0[] This document contains extensions which are not ratified by Khronos, and as such is not a ratified Specification, though it contains text from (and is a superset of) the ratified {apinameCR} Specification. The ratified versions of the {apinameCR} Specification can be found at {apiUrlCore} (core only) ifndef::VKSC_VERSION_1_0[] and {apiUrlKHR} (core with all ratified extensions) endif::VKSC_VERSION_1_0[] . endif::ratified_core_spec[] // "Successor Specification" section This Specification contains substantially unmodified functionality from, and is a successor to, Khronos specifications including ifdef::VKSC_VERSION_1_0[Vulkan, OpenGL SC] OpenGL, OpenGL ES and OpenCL. // "Normative Wording" section The Khronos Intellectual Property Rights Policy defines the terms 'Scope', 'Compliant Portion', and 'Necessary Patent Claims'. Some parts of this Specification are purely informative and so are EXCLUDED the Scope of this Specification. The <> section of the <> defines how these parts of the Specification are identified. Where this Specification uses <>, defined in the <> or otherwise, that refer to enabling technologies that are not expressly set forth in this Specification, those enabling technologies are EXCLUDED from the Scope of this Specification. For clarity, enabling technologies not disclosed with particularity in this Specification (e.g. semiconductor manufacturing technology, hardware architecture, processor architecture or microarchitecture, memory architecture, compiler technology, object oriented technology, basic operating system technology, compression technology, algorithms, and so on) are NOT to be considered expressly set forth; only those application program interfaces and data structures disclosed with particularity are included in the Scope of this Specification. For purposes of the Khronos Intellectual Property Rights Policy as it relates to the definition of Necessary Patent Claims, all recommended or optional features, behaviors and functionality set forth in this Specification, if implemented, are considered to be included as Compliant Portions. // "Normative References" section Where this Specification identifies specific sections of external references, only those specifically identified sections define <> functionality. The Khronos Intellectual Property Rights Policy excludes external references to materials and associated enabling technology not created by Khronos from the Scope of this Specification, and any licenses that may be required to implement such referenced materials and associated technologies must be obtained separately and may involve royalty payments.

The non-ratified section includes links to the ratified // Vulkan 1.3 Specifications in the Vulkan Registry. // - The "Successor Specification" section cites OpenGL, OpenGL ES, and // OpenCL. // - The "Normative Wording" section links to the Vulkan Specification // introduction instead of the "[Document Conventions]" placeholder, and // links to sections describing technical terminology and the glossary. // - The "Normative References" section links to the "Normative References" // section of the Specification. // - The trademarks section cites only those trademarks relevant to Vulkan.
