Hi Becky!
The question of yours I was referring to was

Given a model of M vertices, M ∈ I := {0....M-1} you want to encode into a
d-dimensional texture, you have to define a an (injective, "one-on-one")
function
I := {0....M-1} ⊂ {ℕ+ ∪ {0}}
f: I -> ℝ^d
and store and retrieve vertex data according to that mapping.
With kind regards,
S.
