I was stating that from the perspective that such would be "an algorithmic
process" rather than a function {}.
What you're proposing seems awfully similar to how slope and aoi already work,
no? Perhaps there's a way to piggyback on those in SDL, or repurpose that
already-written source code for the normal perturbation?
Thinking about this some more today reminded me that I am not at all clear about
how a scalar function perturbs a normal vector. Maybe this got covered in the
quilted pattern thread - I will have to look. It would be nice if this was
covered in the docs somehow.
It also caused me to wonder if there is a way to define a pattern in SDL that
has an rgb output, such that the .r .g and .b could be used. The average {}
pattern?
If so, then could we in theory have "vector functions" by rolling 3 pigment
{function {}} statements into an average{} block, and then using function
{pigment{}} ?
