while trying to figure out perlin noise I came up with this
_UNBELIEVABLY EXPENSIVE_
function

Code: [Select]

@n1=sin(2*(:x:)*PI) + sin(2*(:y:)*PI)/2
@n2=(sin(4*(:x:+:n1:)*PI) + sin(4*(:y:+:n1:)*PI))/4
@n3=(sin(8*(:x:+:n2:)*PI) + sin(8*(:y:+:n2:)*PI))/8
@n4=(sin(16*(:x:+:n3:)*PI) + sin(16*(:y:+:n3:)*PI))/16
@n5=(sin(32*(:x:+:n4:)*PI) + sin(32*(:y:+:n4:)*PI))/32
@n6=(sin(64*(:x:+:n5:)*PI) + sin(64*(:y:+:n5:)*PI))/64
@n7=(sin(128*(:x:+:n6:)*PI) + sin(128*(:y:+:n6:)*PI))/128
@n8=(sin(256*(:x:+:n7:)*PI) + sin(256*(:y:+:n7:)*PI))/256


@H=:r:/8

@S=0

@L=1-(:n1:+:n2:+:n3:+:n4:+:n5:+:n6:+:n7:+:n8:)*.8

I think I'm going to start over useing wxwidgets, the basic framework is simple so it shouldn't take too long to rebuild, and I'll make use to make an actual image handleing class this time, then I'll be able to do layers, and THEN it'd be easy to do things like perlin noise, on a plus it'd also be an absolute snap to get loading of images, then you could do manipulation of exsisting textures. the variable code is off in it's own little world so I can still develop it in the exsisting project without haveing to worry about porting issues.

Wait... could this tool create tileable water animations?

That would be great!

Does your generator support random (rnd) numbers?

[Bobboau]

yes and yes

[Bobboau]

well I learned a lot about wxwidgets the last few days, maybe I can put that to use on wxfred.
anyway, this is the new interface, note the whole layer system (and the tumbnail views), it's prety unstable (cause I don't seem to fully understand the list control totaly) but you should be able to get a jist of what I've got in mind.

That proximus effect is the most organic, awesome looking and usable one you've yet devised. There's no hint of the spirograph look from some of the others, it is killer. 

[Bobboau]

that is from the new layering system, you can make perlineque noise and use that for later use you can add it to a spyrography looking thing then use that for a sine function and get cool turbulence effects.

not going to be able to work on this much for a few days, but here is a better example of fractal noise at work

still haven't been able to do any work on this, but here is something I made just a little while ago
