Hi.
Your function
f[a_, b_, c_] := a + b + c
Create your list of points.
Tuples[{0, 1}, 3]
{{0, 0, 0}, {0, 0, 1}, {0, 1, 0}, {0, 1, 1}, {1, 0, 0}, {1, 0, 1}, {1,
1, 0}, {1, 1, 1}}
And here is the requested evaluation
f@@@lst
{0,1,1,2,1,2,2,3}
Cheers
Dimitris

f@@@lst is the operator form of Apply[f,lst,{1}]
