# setIntersectionFunctionTables(_:range:)

Encodes references to an array of ray-tracing intersection-function tables into the argument buffer.

## Declaration

```swift
func setIntersectionFunctionTables(_ intersectionFunctionTables: [(any MTLIntersectionFunctionTable)?], range: Range<Int>)
```

## Parameters

- `intersectionFunctionTables`: An array of intersection-function tables the method encodes.
- `range`: A range of indices within the argument buffer for each element in intersectionFunctionTables. The values correspond to either the index IDs of declarations in Metal Shading Language (MSL) or the doc://com.apple.metal/documentation/Metal/MTLArgumentDescriptor/index property of doc://com.apple.metal/documentation/Metal/MTLArgumentDescriptor instances.
