# MeshViewIndicesNV(3) Manual Page

## Name

MeshViewIndicesNV - Indices of views processed by a mesh or task shader

Loading… please wait.

## Description

`MeshViewIndicesNV`

  Decorating a variable with the `MeshViewIndicesNV` built-in decoration will make that variable contain the mesh view indices. The mesh view indices is an array of values where each element holds the view number of one of the views being processed by the current mesh or task shader invocations. The values of array elements with indices greater than or equal to `MeshViewCountNV` are undefined. If the value of `MeshViewIndicesNV`[i] is j, then any outputs decorated with `PerViewNV` will take on the value of array element i when processing primitives for view index j.

Valid Usage

- VUID-MeshViewIndicesNV-MeshViewIndicesNV-04290
  The `MeshViewIndicesNV` decoration must be used only within the `MeshNV` or `TaskNV` `Execution` `Model`

- VUID-MeshViewIndicesNV-MeshViewIndicesNV-04291
  The variable decorated with `MeshViewIndicesNV` must be declared using the `Input` `Storage` `Class`

- VUID-MeshViewIndicesNV-MeshViewIndicesNV-04292
  The variable decorated with `MeshViewIndicesNV` must be declared as an array of scalar 32-bit integer values
