Modifications to the OpenGL Shading Language Specification, Version 4.50
Including the following line in a shader can be used to control the
language features described in this extension:
#extension GL_EXT_multiview : <behavior>
where <behavior> is as specified in section 3.3
New preprocessor #defines are added to the OpenGL Shading Language:
#define GL_EXT_multiview 1
Modify Section 7.1 (Built-In Language Variables), p. 118
Add to the list of vertex, tessellation control, tessellation
evaluation, geometry, and fragment shader built-ins:
highp int gl_ViewIndex;
Add the following description for gl_ViewIndex:
The input variable gl_ViewIndex is available in vertex, tessellation,
geometry, and fragment shading languages and corresponds to the
ViewIndex SPIR-V input. See the Vulkan API specification for how this
value is interpreted.
