GLSL doesn't allow recursion.

Dammit, forked lightning texture would be so frigging easy if I could do it recursively, but now I have to do it iterative.

Do you have any idea how much code it takes to iterate a fractal?

I'd try to cheese it and alternate two identical functions, but it only takes bottom-up function hierarchy and doesn't let you prototype either  >=[

I dearly, dearly wish I knew what you were saying, @Bee...

alternate two identical functions

I almost understood this

but wouldn't identical functions be

identical

Eh, recursion does not make sense on a gpu anyway. I think it depends on the fractal and how it recurses to figure out how much code it takes to do it non recursively.

It's just forked lightning down to about depth 4.  I'd call recursion a couple extra times if it needs to UV tile, but it's nothing stack-blowing.  So I get to hardcode four layers of for-loops and keep track of four layers worth of iterative parameters.  Joy.

snowbull: that's the cheap workaround if it doesn't allow strict recursion, yeah :P

It doesn't let you call f(x) = stuff with f(x), so my next idea was f(x) = stuff with g(x), g(x) = same stuff with f(x).  But since it doesn't allow prototyping either, only one of those functions is low enough on the page to know the other exists.

recursive functions are the work of the devil

maybe they realized that
