# setIntersectionFunctionTables(_:bufferRange:) Binds multiple intersection function tables to the buffer argument table, allowing you to call their functions on the GPU. ``` func setIntersectionFunctionTables(_ intersectionFunctionTables: [(any MTLIntersectionFunctionTable)?], bufferRange: Range) ``` ## Parameters `intersectionFunctionTables` An array of [`MTLIntersectionFunctionTable`](/documentation/Metal/MTLIntersectionFunctionTable) instances to bind. `bufferRange` The argument buffer table indices to bind each of the `intersectionFunctionTables` to, in the order they appear. ## Discussion> Warning: > This method requires that the number of instances in `visibleFunctionTables` be the same as the length of `bufferRange`. --- Copyright © 2026 Apple Inc.
