Description
This extension adds support for the following SPIR-V extension in Vulkan:
SPV_NV_viewport_array2
which allows a single primitive to be broadcast to multiple viewports
and/or multiple layers. 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
.
