## Name

TileOffsetQCOM - Tile offset of a shader invocation

Loading… please wait.

## Description

`TileOffsetQCOM`

  The `TileOffsetQCOM` decoration can be applied to a shader input which will be filled with the framebuffer coordinates of the active tile.

  When per-tile execution model is enabled, for the current shader invocation x and y components of `TileOffsetQCOM` reflect the framebuffer integer coordinates of the top-left texel of the tile corresponding to the shader invocation.

  Otherwise, the x and y components of `TileOffsetQCOM` are filled with (0,0).

Valid Usage

- VUID-TileOffsetQCOM-TileOffsetQCOM-10626
  The `TileOffsetQCOM` decoration must be used only within the `Fragment` `Execution` `Model` or `GLCompute` `Execution` `Model`

- VUID-TileOffsetQCOM-TileOffsetQCOM-10627
  The variable decorated with `TileOffsetQCOM` must be declared using the `Input` `Storage` `Class`

- VUID-TileOffsetQCOM-TileOffsetQCOM-10628
  The variable decorated with `TileOffsetQCOM` must be declared as a two-component vector of 32-bit integer values
