Which of these expressions would be more efficient when replicating?

Question

I am assuming that an EventVariable driven exponentiation is likely to be heavier than a SmallTalk constructed lookup. But I may be wrong! Perhaps SSC could confirm the best practice when replicating...

Example 1: "Realtime exponentiation"
!resonance clipTo01 ** 1.8

 

Example 2: "Interpolated lookup into 10 points"

| resLookUp |

resLookUp := (0 to: 1 by: 0.1) collect: [:i |  ( i @ ( i ** 1.8 ) ) ].
!resonance clipTo01 into: resLookUp

 

Answer 1

The lookup is probably more efficient. You can also drop the clipTo01 for the lookup example, since the into: will do that internally.
