Milkdrop and fractals (Seeking input from Martin) - Page 2

mfbscs · 26th June 2012, 03:00

Guys,

I have the Dr. Orion Lawlor real-time fractal flames code to a point where I am ready to start getting help and collaborating with it. It's nowhere close to being in a release state, but at least it's to a point where it can begin getting worked on. I know MD isn't the place to discuss it, so I just thought I'd make a last post here to note that I replied to my original post at the ES site http://www.electricsheep.org/node/4261

Thanks again for all of the replies.

PS - See you there Flexi?

sounds good! I have inspected the code and the runnable software, but i had found only one "preset" that worked fast enough (25+fps, below 20 is no fun) for a true realtime animation only my old PC - that's one reason why i left it again. I'm very curious anyway!

I had also missed this post by Scott Draves himself:

Flexi, would you be interested in looking at this? I would like to post the code online in a public repository.

Btw, I am using a GeForce GTX 460 with 1GB of RAM, which seems to give decent frame rates. This stuff is admittedly not something that is backward looking in terms of hardware, which is why it's only recently being done.

I've played with Fractron and inspected the code as well. Pretty cool, and written in C# !

But note that Fractron uses the usual forward, direct method. What's cool about Orion Lawlor's method is that it uses the inverses of the functions. However, it does have some serious drawbacks.

I'd be game. But i keep track of a few other hobby projects too and I'm a busy guy...

mfbscs · 6th July 2012, 20:04

Ok, I'll let you know when I get it uploaded. It will be posted on Google code.

I dont want to open a new topic and since youre already talking about presets functions I just ask here. Is there any difference between

shape_0_init1=t1 = rand(100)*0.01;

and

shape_0_init1=t1 = int(rand(100))*0.01;

?

Im sorting and found some nearly identical presets except theses difference and just got interested.

Nitorami · 7th August 2012, 15:11

Yes

rand(100) yields a float, which means the result can be any value between 0 and 100

int(rand(100)) rounds this to whole numbers only, i.e. 0,1,2....99.

Rapisho · 7th August 2012, 17:21

Is there a reason why there are duplicates of presets where int is added?

Nitorami · 7th August 2012, 21:57

Well, I guess the author had a reason to change it. Maybe to maintain compatibility of the preset with the actual milkdrop version. I remember that in a very old version the rand() function always delivered whole (integer) numbers, so the preset may not have worked properly with a newer version, where rand() was changed to float. Adding the int() function would maintain backwards compatibility.

Rapisho · 8th August 2012, 01:29

So it is be better if I keep the ones with int() to avoid problems in the future? Actually I thought the original versions were better.

Nitorami · 8th August 2012, 08:05

There is no reason why a future milkdrop version should change the handling of rand() again, so simply keep the ones you like best.

Rapisho · 8th August 2012, 10:20

One more question (for now

): the preset that I have attached fails sometimes or at least for the first few seconds, is it possible to fix this?

Nitorami · 8th August 2012, 17:27

I don't know what you mean by "fails" - it works fine for me except ocasionally it tends to be overbright / white. Is that what you mean ?

Rapisho · 8th August 2012, 18:38

Yes, for me its often just white with a few colored outlines and parts.

€: I did some testing and noticed it happens only when switching to next preset by pressing space or when it loads automatically, not when browsing through the list.

Nitorami · 8th August 2012, 20:49

Yes I see... here is a quick fix, not perfect but should avoid the white screen. I won't do any more, I find it really a pain to think into another person's code, even if it is as simple as this one.

Rapisho · 8th August 2012, 22:38

Thx its way better now.

carmatic · 18th February 2013, 03:55

sorry for digging up this old thread, but wouldnt it be cool if milkdrop could do something like this in realtime ...

Rapisho · 18th February 2013, 12:10

These presets have some similarities though they dont have much beat detection.

carmatic · 18th February 2013, 13:26

ah thank you for sharing them, these presets look quite impressive

Nitorami · 19th February 2013, 19:45

The above are mashups of my original mandelbox code

And I can say with quite some confidence this is the most you can get out of milkdrop when it comes to 3D fractals.
