# setTileIntersectionFunctionTable(_:bufferIndex:)

Assigns an intersection function table to an entry in the tile shader argument table.

## Declaration

```swift
func setTileIntersectionFunctionTable(_ intersectionFunctionTable: (any MTLIntersectionFunctionTable)?, bufferIndex: Int)
```

## Parameters

- `intersectionFunctionTable`: An doc://com.apple.metal/documentation/Metal/MTLIntersectionFunctionTable instance the command assigns to an entry in the tile shader argument table for intersection function tables.
- `bufferIndex`: An integer that represents the entry in the tile shader argument table for intersection function tables that stores a record of intersectionFunctionTable.

## Discussion
