### `Optional`applyGlobeMatrix[](#applyglobematrix)

applyGlobeMatrix?: boolean

Set to true if the globe matrix should be applied (i.e. when rendering globe)

### `Optional`applyTerrainMatrix[](#applyterrainmatrix)

applyTerrainMatrix?: boolean

Set to true if the terrain matrix should be applied (i.e. when rendering terrain)

### overscaledTileID[](#overscaledtileid)
