New Flame Paper

It's been a long time coming but Erik and I are prereleasing a new and updated version of the fractal flame paper. You can download it here. This is the definitive explanation of all aspects of the visual language that's the basis for Apophysis and Electric Sheep.

Can't download new paper...

I have been trying to download the new paper but the download stalls.
I am using Firefox, WinXP. Is there some kind of limiter in this file?

i just tried the link to the

i just tried and it downloaded fine in about a minute.

I still can not download

I still can not download this file. Anyone else have trouble with it?

Is this how it works?

Ok so I am really trying to understand how the numbers in IFS work for fractals, but I'm only a senior in high school so there is still a lot I need to learn in the way of math. The notation is half my problem.

this is how I understand how it works:

to make the Sierpinski triangle first a point is chosen (I still don't understand how the initial point is chosen)
Then a random function is chosen F1, F2, or F3

F1 = input is the previous point and output is halfway to (0,0)
F2 = input is the previous point and output is halfway to (1,0)
F3 = input is the previous point and output is halfway to (0,1)

for each pixel there is a counter, when the point falls into the area of the pixel it's counter goes up one.
the new point is the input of the next random function.
this repeats thousands of times (or more).
the pixels with its counter greater than zero are colored in. the ones that aren't are transparent. the ones with the largest count are completely opaque and the ones with less count are slightly transparent.
all of these things things come together to make an image (not including the other enhancements Flam3 has.)

Is this how it works or am I completely off?

Initial points

There is more than one initial point. The initial points are randomly disbursed throughout the biunit square (the square that covers x from -1 to 1 and y from -1 to 1). I am confused as to whether all these points are transformed in parallel (all at once) by the same randomly (well with a certain probability) chosen function, or if a different function is used for each point. My guess is that probably the later happens.

I believe so

It's been a while since doing Sierpinski's triangle, but that sounds right. Each point is chosen randomly from inside the triangle and then moved halfway to one of the vertices. This is repeated until you have the image. It would make sense that the pixels with the greatest counts are opaque and the ones that don't have any are transparent.

Nice work! That Xform list

Nice work! That Xform list was in bad need of updating. :-)

Hole in NGon (variation 38) documentation

The documentation for NGon seems to have a couple of lines that accidently got deleted. t2 (and presumably t1) are not defined anywhere.

Thx for the catch

t2 should actually be p2 in that calculation. I've fixed that and sent the correction to spot.

NGon docs

In that case, why is there only t3 and t4? What happened to t1 and t2? Given that all the other xforms have inside functions listed as t1, t2, t3... it might be a good idea to change this to avoid confusion.
