Class EXTShaderViewportIndexLayer


  • public final class EXTShaderViewportIndexLayer
    extends java.lang.Object
    This extension adds support for the ShaderViewportIndexLayerEXT capability from the SPV_EXT_shader_viewport_index_layer extension in Vulkan.

    This extension allows variables decorated with the Layer and ViewportIndex built-ins to be exported from vertex or tessellation shaders, using the ShaderViewportIndexLayerEXT capability.

    When using GLSL source-based shading languages, the gl_ViewportIndex and gl_Layer built-in variables map to the SPIR-V ViewportIndex and Layer built-in decorations, respectively. Behaviour of these variables is extended as described in the GL_ARB_shader_viewport_layer_array (or the precursor GL_AMD_vertex_shader_layer, GL_AMD_vertex_shader_viewport_index, and +GL_NV_viewport_array2 extensions+).

    Note

    The ShaderViewportIndexLayerEXT capability is equivalent to the ShaderViewportIndexLayerNV capability added by VK_NV_viewport_array2.
