# setVertexIntersectionFunctionTables(_:bufferRange:)

Assigns multiple intersection function tables to a range of entries in the vertex shader argument table.

## Declaration

```swift
func setVertexIntersectionFunctionTables(_ functionTables: [(any MTLIntersectionFunctionTable)?], bufferRange: Range<Int>)
```

## Parameters

- `functionTables`: An array of doc://com.apple.metal/documentation/Metal/MTLIntersectionFunctionTable instances the command assigns to entries in the vertex shader argument table for intersection function tables.
- `bufferRange`: A span of integers that represent the entries in the vertex shader argument table for intersection function tables. Each entry stores a record of the corresponding element in functionTables.

## Discussion

Discussion By default, the intersection function table at each index is nil. note: The Objective-C version of this method is setVertexIntersectionFunctionTables:withBufferRange:.
