Of course, I still have to get a CPAN reg, work this out with the necessary parties, etc., but I'd like to have a working module first, then worry about whether I'm allowed to put it on CPAN.
I just managed to get the auto-centroiding working; by generating them according to simple-and-usually-followed rules, it saves having to input them. It seemed like the kind of thing that a 'Simple' namespace would imply. (Which is to say, it automatically does what you need 70-90% of the time, and the rest of the time lets more feature-full modules be useful.)
The very real problem is that I have no clue how Kosko did the bounded-sum calculation (combining two triangles to provide a curve approximation) nor do I have the faintest idea how to fake it. Instead, I'm doing something dumber and cruder -- turning overlapping triangles into a quadrilateral and calculating it as if it's a curve -- until I can figure out the bounded-sum calculation.
Other than these issues, things are going well for the module. Were I really optimistic, I'd say that I could have it finished tomorrow; probably, though, it'll get finished later this week.
