Khronos grants a conditional copyright license to use and reproduce the
unmodified Specification for any purpose, without fee or royalty, EXCEPT no
licenses to any patent, trademark or other intellectual property rights are

Khronos makes no, and expressly disclaims any, representations or
warranties, express or implied, regarding this Specification, including,

Under no circumstances will Khronos, or any of its Promoters, Contributors

This Specification has been created under the Khronos Intellectual Property
Rights Policy, which is Attachment A of the Khronos Group Membership
Agreement available at www.khronos.org/files/member_agreement.pdf, and which
defines the terms 'Scope', 'Compliant Portion', and 'Necessary Patent Claims'.
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.

This Specification contains substantially unmodified functionality from, and is a
successor to, Khronos specifications including OpenGL, OpenGL ES and OpenCL.

Some parts of this Specification are purely informative and so are EXCLUDED from
the Scope of this Specification. The <<introduction-conventions>> section of the
<<introduction>> defines how these parts of the Specification are identified.

Where this Specification uses <<introduction-technical-terminology,technical
terminology>>, defined in the <<glossary>> 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.

Where this Specification includes <<introduction-normative-references,
normative references to external documents>>, only the specifically
identified sections of those external documents are INCLUDED in the Scope of
this Specification. If not created by Khronos, those external documents may
contain contributions from non-members of Khronos not covered by the Khronos
Intellectual Property Rights Policy.
