A new shader built-in output @ViewportMaskNV@ -- is provided, which allows a single primitive to be output to multiple -- viewports simultaneously. Also, a new SPIR-V decoration is added to -- control whether the effective viewport index is added into the variable -- decorated with the @Layer@ built-in decoration. These capabilities allow -- a single primitive to be output to multiple layers simultaneously. -- -- This extension allows variables decorated with the @Layer@ and -- @ViewportIndex@ built-ins to be exported from vertex or tessellation -- shaders, using the @ShaderViewportIndexLayerNV@ capability. -- -- This extension adds a new @ViewportMaskNV@ built-in decoration that is -- available for output variables in vertex, tessellation evaluation, and -- geometry shaders, and a new @ViewportRelativeNV@ decoration that can be -- added on variables decorated with @Layer@ when using the -- @ShaderViewportMaskNV@ capability. -- -- When using GLSL source-based shading languages, the @gl_ViewportMask@[] -- built-in output variable and @viewport_relative@ layout qualifier from -- @GL_NV_viewport_array2@ map to the @ViewportMaskNV@ and -- @ViewportRelativeNV@ decorations, respectively. Behaviour is described -- in the @GL_NV_viewport_array2@ extension specificiation. -- -- Note -- -- The @ShaderViewportIndexLayerNV@ capability is equivalent to the -- @ShaderViewportIndexLayerEXT@ capability added by -- @VK_EXT_shader_viewport_index_layer@. -- -- == New Enum Constants -- -- - 'NV_VIEWPORT_ARRAY2_EXTENSION_NAME' -- -- - 'NV_VIEWPORT_ARRAY2_SPEC_VERSION' -- -- - 'NV_VIEWPORT_ARRAY_2_EXTENSION_NAME' -- -- - 'NV_VIEWPORT_ARRAY_2_SPEC_VERSION' -- -- == New or Modified Built-In Variables -- -- - (modified) -- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#interfaces-builtin-variables-layer Layer> -- -- - (modified) -- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#interfaces-builtin-variables-viewportindex ViewportIndex> -- -- - <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#interfaces-builtin-variables-viewportmask ViewportMaskNV> -- -- == New Variable Decoration -- -- - <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#interfaces-builtin-variables-layer ViewportRelativeNV in Layer> -- -- == New SPIR-V Capabilities -- -- - <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#spirvenv-capabilities-table-ShaderViewportIndexLayerNV ShaderViewportIndexLayerNV> -- -- - <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#spirvenv-capabilities-table-ShaderViewportMaskNV ShaderViewportMaskNV> -- -- == Version History -- -- - Revision 1, 2017-02-15 (Daniel Koch) -- -- - Internal revisions -- -- == See Also -- -- No cross-references are available -- -- == Document Notes -- -- For more information, see the -- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#VK_NV_viewport_array2 Vulkan Specification> -- -- This page is a generated document.
