Description

ViewIndex

The ViewIndex decoration can be applied to a shader input which will be filled with the index of the view that is being processed by the current shader invocation.

If multiview is enabled in the render pass, this value will be one of the bits set in the view mask of the subpass the pipeline is compiled against. If multiview is not enabled in the render pass, this value will be zero.

Valid Usage

  • VUID-ViewIndex-ViewIndex-04401
    The ViewIndex decoration must be used only within the MeshEXT, Vertex, Geometry, TessellationControl, TessellationEvaluation or Fragment Execution Model

  • VUID-ViewIndex-ViewIndex-04402
    The variable decorated with ViewIndex must be declared using the Input Storage Class

  • VUID-ViewIndex-ViewIndex-04403
    The variable decorated with ViewIndex must be declared as a scalar 32-bit integer value
