## Name

PrimitiveLineIndicesEXT - Indices of line primitives in a mesh shader

Loading… please wait.

## Description

`PrimitiveLineIndicesEXT`

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

Valid Usage

- VUID-PrimitiveLineIndicesEXT-PrimitiveLineIndicesEXT-07047
  The `PrimitiveLineIndicesEXT` decoration must be used only within the `MeshEXT` `Execution` `Model`

- VUID-PrimitiveLineIndicesEXT-PrimitiveLineIndicesEXT-07048
  The `PrimitiveLineIndicesEXT` decoration must be used with the `OutputLinesEXT` `Execution` `Mode`

- VUID-PrimitiveLineIndicesEXT-PrimitiveLineIndicesEXT-07049
  The variable decorated with `PrimitiveLineIndicesEXT` must be declared using the `Output` `Storage` `Class`

- VUID-PrimitiveLineIndicesEXT-PrimitiveLineIndicesEXT-07050
  The variable decorated with `PrimitiveLineIndicesEXT` must be declared as an array of two component vector 32-bit integer values

- VUID-PrimitiveLineIndicesEXT-PrimitiveLineIndicesEXT-07051
  All index values of the array decorated with `PrimitiveLineIndicesEXT` must be in the range [0, N-1], where N is the value specified by the `OutputVertices` `Execution` `Mode`

- VUID-PrimitiveLineIndicesEXT-PrimitiveLineIndicesEXT-07052
  The size of the array decorated with `PrimitiveLineIndicesEXT` must match the value specified by `OutputPrimitivesEXT`
