+    OpenGL Extension #538

+    OpenGL ES Extension #319

+

+Dependencies

+

+    OpenGL 4.0 or OpenGL ES 3.2 are required.

+

+    This extension is written against the OpenGL 4.6 specification

+    (Core Profile) (February 2, 2019) and OpenGL ES 3.2 specification

+    (February 2, 2019).

+

+    This extension is written against the OpenGL ES Shading Language 3.20.05

+    specification and OpenGL Shading Language 4.60.6 specification.

+    

+    This extension interacts with OVR_multiview2.

+    

+    OVR_multiview is required.

+

+Overview

+

+    OVR_multiview introduced multiview rendering to OpenGL and OpenGL ES.

+    

+    This extension removes one of the limitations of the OVR_multiview 

+    extension by allowing the use of tessellation control, tessellation 

+    evaluation, and geometry shaders during multiview rendering. 

+    OVR_multiview by itself forbids the use of any of these shader types.

+    

+    When using tessellation control, tessellation evaluation, and geometry 

+    shaders during multiview rendering, any such shader must use the 

+    "num_views" layout qualifier provided by the matching shading language 

+    extension to specify a view count. The view count specified in these 

+    shaders must match the count specified in the vertex shader. Additionally, 

+    the shading language extension allows these shaders to use the 

+    gl_ViewID_OVR built-in to handle tessellation or geometry shader processing 

+    differently for each view.

+    

+    OVR_multiview2 extends OVR_multiview by allowing view-dependent values

+    for any vertex attributes instead of just the position. This new extension

+    does not imply the availability of OVR_multiview2, but if both are available,

+    view-dependent values for any vertex attributes are also allowed in 

+    tessellation control, tessellation evaluation, and geometry shaders.

+    

+    

+New Tokens

+

+    None.

+

+    

+New Procedures and Functions

+

+    None.

+    

+    

+Modifications to Chapter 9 of the OpenGL ES 3.2 Specification as well as

+Chapter 9 of the OpenGL 4.6 Specification (Framebuffers and Framebuffer 

+Objects) 

+    

+    Modify the subsection 9.2.2.2 (Multiview Images) which has been added by 

+    OVR_multiview:

+    

+    Remove from the list of restrictions ("In this mode there are several 

+    restrictions:") the following items:

+

+    "- no tessellation control or evaluation shaders (section 11.1.3.11)

+    - no geometry shader (section 11.1.3.11)"

+        

+    effectively allowing the usage of multiview rendering with tessellation and

+    geometry shaders.

+    

+    In the same list replace

+        "- in fragment shader the contents of gl_Layer are undefined"

+    with

+        "- reads and writes of gl_Layer by any shaders are undefined".

+    

+    

+Modifications to Chapter 11 of the OpenGL ES 3.2 Specification as well

+as Chapter 11 of the OpenGL 4.6 Specification (Programmable Vertex Processing)

+

+    Modify section 11.1.3.11 (Validation) by removing the following condition

+    from the list of reasons that may result in an INVALID_OPERATION error

+    being generated by any command that transfers vertices to the GL

+    (added by OVR_multiview) after

+    "Any attachment of the draw framebuffer is multiview (section 9.2.8)

+      and any of the following conditions are true:":

+

+    "- There is an active program for tessellation control, tessellation

+      evaluation, or geometry stages, or".

+    

+    

+    Modify section 11.1.3.11 (Validation) by adding the following 

+    item to the bullet point list of conditions generating an INVALID_OPERATION:

+        "The active program for the vertex, tessellation control, tessellation 

+        evaluation, or geometry shader stages contains an executable that declared 

+        a multiview view count using the "num_views" layout qualifier, but the 

+        active program for another one of these stages includes an executable that 

+        declared a different view count or failed to declare any view count."

+

+    

+Modifications to The OpenGL ES Shading Language Specification, Version 3.20.05

+and The OpenGL Shading Language Specification, Version 4.60.6:

+

+    Including the following line in a tessellation control, tessellation evaluation, 

+    or geometry shader can be used to control the language features described in 

+    this extension:

+

+      #extension GL_EXT_multiview_tessellation_geometry_shader : <behavior>

+

+    where <behavior> is as specified in section 3.5.

+

+    A new preprocessor #define is added to the OpenGL ES Shading Language

+    as well as the OpenGL Shading Language for those shaders:

+

+      #define GL_EXT_multiview_tessellation_geometry_shader 1

+    

+    In section "Input Layout Qualifiers" a new paragraph was added by OVR_multiview

+    (section 4.3.8.1 in the OpenGL ES Shading Language Specification, version 3.00.04,

+    which moved to section 4.4.1 in version 3.20.05 of the OpenGL ES Shading Language 

+    Specification and version 4.60.6 of the OpenGL Shading Language Specification).

+    

+    In this new paragraph replace

+        "Vertex shaders also allow the following layout qualifier on 'in' only"

+    with

+        "Vertex, tessellation control, tessellation evaluation and geometry shaders 

+        also allow the following layout qualifier on 'in' only".

+    

+    In the following paragraph of the same addition by OVR_multiview replace

+        "If multiple vertex shaders attached to a

+        single program object declare num_views, the declarations must be

+        identical; otherwise a link-time error results."

+    with

+        "If multiple shaders of the same type attached to a

+        single program object declare num_views, the declarations must be

+        identical; otherwise a link-time error results.

+        

+        If any vertex, tessellation control, tessellation evaluation, or 

+        geometry shader in a single program object declares a view count using 

+        'num_views', at least one shader of each type present in the program must 

+        declare a view count and all such declarations must match. If there is a 

+        missing or mismatched view count declaration, a link-time error results."

+    

+

+Modifications to Section 7.1 "Built-in Language Variables"

+    

+    Replace the following paragraph added by OVR_multiview

+        "Add the following to the list of built-in variables that are intrinsically

+        declared in the vertex and fragment shading languages:

+

+            in mediump uint gl_ViewID_OVR;"

+    with

+        "Add the following to the list of built-in variables that are intrinsically

+        declared in the vertex, tessellation control, tessellation evaluation 

+        geometry and fragment shading languages:

+

+            [[ If implemented in the OpenGL ES Shading Language ]]

+            in mediump uint gl_ViewID_OVR;

+            

+            [[ If implemented in the OpenGL Shading Language ]]

+            in uint gl_ViewID_OVR;"

+    

+

+Interactions with OVR_multiview2:

+

+    If OVR_multiview2 is supported the restriction from OVR_multiview that only

+    gl_Position is allowed to depend on gl_ViewID_OVR is also lifted from the 

+    tessellation control, tessellation evaluation, and geometry 

+    shaders.

+    

+    

+Issues

+

+    (1) This extension is based on an OVR extension, why call it EXT?

+    

+    While started as a single vendor extension, OVR_multiview and OVR_multiview2

+    are already supported by multiple vendors. This new extension also has the 

+    support from multiple vendors to be specified as EXT.

+    

+    (2) Should the functions and tokens introduced by OVR_multiview be renamed

+    to have EXT suffixes?

+    

+    No. While it is unusual to mix a vendor suffix with EXT in this "family" of

+    extensions, the main goal of this extension is to remove restrictions of 

+    OVR_multiview while keeping source code compatibiliy where possible. It is 

+    up to a successor of OVR_multiview to change the names (e.g. to revisit 

+    the unusual second underscore in gl_ViewID_OVR). The intent of this extension 

+    is to change the functionality while "inheriting" the names of the base 

+    multiview extension. 

+

+    (3) Are separable program objects with multiview allowed?

+    

+    Yes. Note that when using separable program objects, each program object 

+    can have its own multiview view count declared with the "num_views" layout 

+    qualfiier. When using separable programs, a draw-time error will occur if 

+    the view count for the programs used by the vertex, tessellation control,

+    tessellation evaluation, and geometry stages don't match.

+    OpenGL 4.0 or OpenGL ES 3.2 are required.

+

+    This extension is written against the OpenGL 4.6 specification

+    (Core Profile) (February 2, 2019) and OpenGL ES 3.2 specification

+    (February 2, 2019).

+

+    OVR_multiview is required.

+

+Overview

+

+    OVR_multiview introduced multiview rendering to OpenGL and OpenGL ES.

+    

+    This extension removes one of the limitations of the OVR_multiview 

+    extension by allowing the use of multisample textures during multiview rendering.

+    

+    This is one of two extensions that allow multisampling when using 

+    OVR_multiview. Each supports one of the two different approaches to 

+    multisampling in OpenGL and OpenGL ES:

+    

+        Core OpenGL and OpenGL ES 3.1+ have explicit support for multisample 

+        texture types, such as TEXTURE_2D_MULTISAMPLE. Applications can access 

+        the values of individual samples and can explicitly "resolve" the 

+        samples of each pixel down to a single color.

+        

+        The extension EXT_multisampled_render_to_texture provides support for 

+        multisampled rendering to non-multisample texture types, such as 

+        TEXTURE_2D. The individual samples for each pixel are maintained 

+        internally by the implementation and can not be accessed directly 

+        by applications. These samples are eventually resolved implicitly to 

+        a single color for each pixel.

+        

+    This extension supports the first multisampling style with multiview 

+    rendering; the OVR_multiview_multisampled_render_to_texture extension 

+    supports the second style. Note that support for one of these multiview 

+    extensions does not imply support for the other.

+    

+    

+New Tokens

+

+    None.

+

+    

+New Procedures and Functions

+

+    None.

+    

+    

+Modifications to Chapter 9 of the OpenGL ES 3.2 Specification as well as

+Chapter 9 of the OpenGL 4.6 Specification (Framebuffers and Framebuffer 

+Objects) 

+    

+Modifications to all sections added and/or modified by OVR_multiview

+

+    Where OVR_multiview references a "two-dimensional array texture", replace 

+    this with "two-dimensional array texture or two-dimensional multisample 

+    array texture" to explicitly allow rendering to multisampled textures.

+    

+    The following is an explicit list of these changes:

+    

+    In subsection 9.2.2.2 (introduced by OVR_multiview) replace

+        "Finally, multiple layers of two-dimensional array textures can be

+        attached to an attachment point."

+    with

+        "Finally, multiple layers of two-dimensional array textures or 

+        two-dimensional multisample array textures can be

+        attached to an attachment point."

+    

+    In the additions to section 9.2.3 (Framebuffer Object Queries) replace

+        "If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_NUM_VIEWS_OVR and the value

+        of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a two-dimensional array texture..."

+    with

+        "If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_NUM_VIEWS_OVR and the value

+        of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a two-dimensional array texture

+        or a two-dimensional multisample array texture..."

+    

+    Also replace

+        "If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_BASE_VIEW_INDEX_OVR and the

+        value of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a two-dimensional array

+        texture..."

+    with

+        "If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_BASE_VIEW_INDEX_OVR and the

+        value of FRAMEBUFFER_ATTACHMENT_OBJECT_NAME is a two-dimensional array

+        texture or a two-dimensional multisample array texture..."

+    

+    In the addition to the end of section 9.2.8 (Attaching Textures to a Framebuffer)

+    replace

+        "Multiple layers of a two-dimensional array texture can be

+        attached as one of the logical buffers of a framebuffer object with the

+        commands"

+    with

+        "Multiple layers of a two-dimensional array texture or a two-dimensional 

+        multisample array texture can be

+        attached as one of the logical buffers of a framebuffer object with the

+        commands"

+    

+    Later in that section under "Errors" replace

+        "An INVALID_VALUE error is generated if:

+        - <texture> is a two-dimensional array texture and <baseViewIndex> +

+Issues

+

+    (1) This extension is based on an OVR extension, why call it EXT?

+    

+    While started as a single vendor extension, OVR_multiview and OVR_multiview2

+    are already supported by multiple vendors. This new extension also has the 

+    support from multiple vendors to be specified as EXT.

+    

+    (2) Can this extension be used together with 

+    OVR_multiview_multisampled_render_to_texture if both are supported?

+    

+    The two extensions can be used together in the same application, but not in 

+    the same framebuffer. OVR_multiview_multisampled_render_to_texture is based 

+    on EXT_multisampled_render_to_texture, which explicitly does not permit a 

+    single framebuffer to contain explicit multisample texture types (from 

+    OpenGL ES 3.1 and core OpenGL) and "multisampled" bindings of non-multisample 

+    texture types.

+

+    OpenGL Extension #536

+    OpenGL ES Extension #317

+

+Dependencies

+

+    OpenGL 4.0 or OpenGL ES 3.2 are required.

+

+    This extension is written against the OpenGL 4.6 specification

+    (Core Profile) (February 2, 2019) and OpenGL ES 3.2 specification

+    (February 2, 2019).

+

+    OVR_multiview is required.

+

+Overview

+

+    OVR_multiview introduced multiview rendering to OpenGL and OpenGL ES.

+    This extension removes one of the limitations of the OVR_multiview 

+    extension by allowing the use of timer queries during multiview rendering. 

+    OVR_multiview does not specify defined behavior for such usage

+    (if implemented in OpenGL or if EXT_disjoint_timer_query is present).

+    

+    

+New Tokens

+

+    None.

+

+    

+New Procedures and Functions

+

+    None.

+    

+    

+Modifications to Chapter 4 of the OpenGL 4.6 Specification (Event Model)

+

+    Remove the following error from section 4.3 (Time Queries) which has

+    been added by OVR_multiview:

+    

+    "Queries where BeginQuery or EndQuery is called with a target of

+    TIME_ELAPSED, or a if QueryCounter is called with a target of TIMESTAMP

+    return undefined values if the draw framebuffer is multiview at any

+    point during their execution."

+    

+    

+Modifications to Chapter 9 of the OpenGL ES 3.2 Specification as well as

+Chapter 9 of the OpenGL 4.6 Specification (Framebuffers and Framebuffer 

+Objects) 

+    

+    Modify the subsection 9.2.2.2 (Multiview Images) which has been added by 

+    OVR_multiview:

+    

+    Remove from the list of restrictions ("In this mode there are several 

+    restrictions:") the following item:

+

+    "- no timer queries (section 4.3)".

+

+    OpenGL Extension #535
+
+Dependencies
+
+    Requires GLX_ARB_create_context.
+
+    This extension is written against the text of the GLX 1.4 specification.
+
+Overview
+
+    This extension allows a GLXContext to be created with a priority
+    hint. It is possible that an implementation will not honour the
+    hint, especially if there are constraints on the number of high
+    priority contexts available in the system, or system policy limits
+    access to high priority contexts to appropriate system privilege
+    level. A query is provided to find the real priority level assigned
+    to the context after creation.

+
+    New attribute values accepted in the <attrib_list> argument

+
+        GLX_CONTEXT_PRIORITY_HIGH_EXT           0x3101

+        GLX_CONTEXT_PRIORITY_LOW_EXT            0x3103
+
+Additions to the GLX_ARB_create_context specification
+
+    Add to the text of attributes supported by glXCreateContextAttribsARB:
+
+        "GLX_CONTEXT_PRIORITY_LEVEL_EXT determines the priority level of
+        the context to be created. This attribute is a hint, as an
+        implementation may not support multiple contexts at some
+        priority levels and system policy may limit access to high
+        priority contexts to appropriate system privilege level. The
+        default value for GLX_CONTEXT_PRIORITY_LEVEL_EXT is
+        GLX_CONTEXT_PRIORITY_MEDIUM_EXT."
+
+Additions to the GLX 1.4 specification
+
+    To Table 3.5 "Context attributes" add the row:
+
+    Attribute                       Type    Description
+    GLX_CONTEXT_PRIORITY_LEVEL_EXT  int     Context priority level
+
+Issues
+
+    Refer to the issues in EGL_IMG_context_priority for further background.
+
+    1) What enumerant values should we use here?
+
+    RESOLVED: Reuse the enums from EGL_IMG_context_priority. The window
+    system binding APIs have trended towards sharing enumerant space. The
+    range is not otherwise assigned for GLX, and Imagination have consented
+    to its reuse in GLX.
