Fractal Fr0st

Fractal Fr0st - 0.1

Description

Fr0st allows you to visualize the results of an iterated funcion system as it is rendered. This is a very early version of it, with lots of planned funcionality missing. The only controls so far are moving the mouse to change the location of the active transform and the left and right keys to switch between transforms. It's hard to explain in non-technical terms, just try it out. If you know how to use Apophysis, you can let your own flame be rendered by Frost.

This is really good. Great work!
So I see you found blitting a 1x1 surface to be faster than setting pixels? That's interesting, lol

Ok, thanks. I got my flame rendered.
Interesting project.

Well, you just need to save the flame as sample.flame in the parameters folder. However, Frost does not render the flame in any way similar to apophysis, it is not meant to be a replacement.

How can I render Apophysis flames in this program?

I've refactored the parsing since 0.1 release, it's much more compact now, but still uses the same ugly flag setting approach.

I find that bug rather strange (doesn't happen to me). Thinking about it, it might be that line ends are getting included in the gradient object, so I would need to call a strip after reading each line.

Thanks for the feedback!

Ooh... very colourful and patterny. Them's scientific words :D

I had one problem,

File "Fractal Fr0st fullscreen.py", line 76, in get_gradient
gradient.append([int(hex_gradient[i:i+2],16),int(hex_gradient[i+2:i+4],16),int(hex_gradient[i+4:i+6],16)]) #converts FFFFFF to (255,255,255)
ValueError: invalid literal for int():

I put a try/except wrapper around it to make it ignore the error (I really could not work out why the error occurs, but it's probably something to do with how you're reading the data from file.. there might be a null character at the end or something strange) Try using hex_gradient=hex_gradient.strip() before that loop?

Apart from that, it worked fine.

I also noticed that you used a 'black.png' which was a big png filled with 1.5% black throughout. You can use this too:

background = pygame.Surface(size)
background.set_alpha(4)

which would be the same (surfaces are initialised to black)

Lastly, your parsing of XML was crude. :P Sounds like something *I'd* do. I know parsing XML trees is annoying. I had to do some for the maps in my game.

Ha ha, I'd love to play with this on acid :)
