# setIntersectionFunctionTable(_:bufferIndex:)

Binds an intersection function table to the buffer argument table, making it callable in your Metal shaders.

```

## Parameters

- `intersectionFunctionTable`: The doc://com.apple.metal/documentation/Metal/MTLIntersectionFunctionTable to bind.
- `bufferIndex`: The index in the buffer argument table the intersection function table binds to.
