intersectionFunctionTableOffset
An offset into the intersection-function table for ray tracing, which applies to the next acceleration-structure motion instance you create with the descriptor.
Declaration
var intersectionFunctionTableOffset: UInt32Discussion
By default, after Metal finds an intersection between a ray and a primitive, it runs your specified intersection function to determine whether the ray actually hit the primitive. To determine which function in the intersection table to call, Metal adds this property to the value specified in the instance’s intersectionFunctionTableOffset, and looks up the entry at that index.
