# PrimitivePointIndicesEXT(3) Manual Page

## Name

PrimitivePointIndicesEXT - Indices of point primitives in a mesh shader

Loading… please wait.

## Description

`PrimitivePointIndicesEXT`

  Decorating a variable with the `PrimitivePointIndicesEXT` decoration will make that variable contain the output array of vertex index values for point primitives.

Valid Usage

- VUID-PrimitivePointIndicesEXT-PrimitivePointIndicesEXT-07041
  The `PrimitivePointIndicesEXT` decoration must be used only within the `MeshEXT` `Execution` `Model`

- VUID-PrimitivePointIndicesEXT-PrimitivePointIndicesEXT-07042
  The `PrimitivePointIndicesEXT` decoration must be used with the `OutputPoints` `Execution` `Mode`

- VUID-PrimitivePointIndicesEXT-PrimitivePointIndicesEXT-07043
  The variable decorated with `PrimitivePointIndicesEXT` must be declared using the `Output` `Storage` `Class`

- VUID-PrimitivePointIndicesEXT-PrimitivePointIndicesEXT-07044
  The variable decorated with `PrimitivePointIndicesEXT` must be declared as an array of scalar 32-bit integer values

- VUID-PrimitivePointIndicesEXT-PrimitivePointIndicesEXT-07045
  All index values of the array decorated with `PrimitivePointIndicesEXT` must be in the range [0, N-1], where N is the value specified by the `OutputVertices` `Execution` `Mode`

- VUID-PrimitivePointIndicesEXT-PrimitivePointIndicesEXT-07046
  The size of the array decorated with `PrimitivePointIndicesEXT` must match the value specified by `OutputPrimitivesEXT`
