Class MTLIntersectionFunctionSignature

  • public final class MTLIntersectionFunctionSignature
extends java.lang.Object
    Signature defining what data is provided to an intersection function. The signature must match across the shading language declaration of the intersection function table, intersection functions in the table, and the intersector using the table. API-Since: 14.0
