2 more!

While watching the stats for the last year, I noticed there were much less posts than I wanted or could have made. This will change. Here are 2 more images from the all-formula project. All the images are named after the formula that originated the fractal, and I will be telling when the formula is from a new formula collection if needed, maybe not. I guess letting too many guesses about how they are made makes the game not as funny. Click the image to see them larger as usual.

The mega formula project, image 1

There are a bunch of images already made. I’ll be posting them one at a time instead of inside galleries. This one is called “Bolla”. As usual, click on the image to see it larger.

Mandalas Gallery 01

Sorry for the long time without any posts but this is not a daily job, is it? OK, enough rantings.

As I said in the previous post I tried the Mandala Project or something. I opened all my UPRs one by one (well not all yet) and applied a kaleidoscope transformation on each layer to create the mandala-like images. Some images work better than others, some images don’t work at all, some give birth to a lot of new images and so on.

For the creation process, I didn’t change any of the original image’s fractal parameters, I just applied the kaleidoscope on the layers and that was it. In very few cases, I did some extra zooming when I thought I could find something more interesting a little deeper, but this wasn’t the case with all images. Of course, lots of panning work was a must to find good images, but there are some images that are just the original image with the transformation without any panning, applied to the image with its original coordinates. Also, I made the “mandalas” in the same order as I made the original images, I started with my very first (saved) image, and went on from there. I’m not sure where I am at this point now (I have about 50 images already made), but I think I’ve tried at least a whole year of images or maybe half a year of UPRs. And this is… still 2002? I think so.

For me, it’s a bit easier to spot the original image that was transformed, but sometimes there aren’t much hints and the new image is a bit different, although it still can be recognizable maybe from its colour scheme. Some “mandalas” kept some parts (or visual characteristics) of the original images a bit intact, like mandelbrot shapes, etc. etc. and this was done on purpose sometimes.

This project is something I’m doing just for fun, while I don’t have enough new images to be added to new fractal galleries.

Here are the first gallery, with 15 images (I guess 16 will look better… maybe I’ll change that):

As some people with some a good attention span might have noticed, the watermark now shows “www.mundofractal.com”. I could grab this domain name and now you can use both the .net or the .com extensions. Hopefully Google won’t get pissed at me for redirecting a domain to this URL.

Some more on fractal movies

I’ve moved the animation that I had saved to a faster computer, but it refused to render, it wasn’t rendering even the very first frame. Time to think a little why it was happening. Maybe some folder permission error, not really a software bug.

In Mandelbulb 3D, in the animation window, you have the option to send back the saved keyframes to the main window (useless feature? Not at all!), so this is what I did. Sent them back, re-rendered each and send them back to the animation timeline, and saved this animation under a new name and in a different folder just to be sure. And it worked.

It’s currently rendering right now with a couple more frames added towards the end of the previous version (but I’ve reduced the number of frames between keyframes from 50 to 25 to see what happens, therefore the movie should be shorter this time) and 150 frames out of a total of 250 are already finished in 18 minutes. Quite an improvement. I think that I can even raise the size of the animations to some sort of “semi-HD” quality. I’ll have to check first if these fractals used here are also faster than others, sometimes when adding a Julia calculation or a “Cutting” things get a bit slower. Anyway, this is much much faster than rendering it in the other computer, that has half of the memory of this one, but the processor is a Celeron while in this other one it’s a quadcore… it’s not RAM that makes the difference here, but the processor. And maybe the video card (I have a Radeon something in the faster computer), but I’m not sure as it doesn’t really help in other softwares like Ultra Fractal to have a faster video card, these cards are more useful with games and… well, 3D processing. Definitely fractals aren’t for slow computers.

One thing that I’ve noticed though even in the preview animation window is that for some reason (or maybe it’s not really happening) is that the keyframes I had already used and all the frames inbetween these are rendered a bit faster than the new added keyframes. Sometimes deeper zooms render a bit slower too, this might be what’s happening as it’s a little deeper in these new frames.

Another thing I’ve noticed that seems to happen at least in this image is that in areas that have a certain depth of field, showing parts of the “sky” (or of a background image), the render gets much slower. The more sky/background, the slower it gets. If the image is filled with just the fractal parts, it goes much faster. The elements that are closer to the camera for example, are rendered much faster in an image that has “sky” parts even though they look much more complex than the plain blue sky behind them. I guess it’s due to the 3D, it has to calculate the distances from for example the border of the fractal to the “horizon” or the “sky”, which is quite far from the camera (I guess this calculation is limited by the iterations as well, it tells the software where the “sky” – the end of the image – is). The difference is brutal. Frames with about 30-40% of “sky” areas can take up to 20 mins to be rendered, maybe more (just one frame!), while others with minimal open areas are rendered in 40 seconds. So a good tip for a fractal animation using Mandelbrot 3D is… avoid these open areas, focus on the fractal details. Which is the most interesting part anyway.

Update: it is really getting slower. Last frames past the #200 are taking 7 mins to be rendered and it’s getting considerably slower from there. Maybe it’s really the zoom, the frame #207 for example has a zoom of 1599946.7something while the very first one is 1x I think or near that. This combined with the lights, shading, etc. make it go slower. And I just found that I’m using the Julia mode and the cutting in this one. Also it seems that the more colours an image have, the more complicated it gets to be rendered. Images that are too colourful like the “Beatle Sugar Cube” below seem to be slower because of the different colours. But sometimes the images need to be that vivid. OK if you like a plain pink shade all over your image, I don’t.

I will try to make some more tests and for example disable the cutting when/if it won’t make a difference in certain keyframes. I think that it works for me more like a guideline if I want to find a Mandelbrot shape inside that mess, for example, or to reveal certain areas of “solid” fractals to see if they have something interesting inside. I’m not sure if I can really reach these internal areas just by zooming in without cutting them first, probably I can’t.

I have read that the common timeframe people spend rendering these animations are “weeks”, so I guess I’m just starting… if I want to add a soundtrack for example, it wouldn’t work if the animation is too short. At 24 frames per second, 2 of these keyframes with the settings I’m using for this new test (25 frames inbetween keyframes) will give me a 2 seconds animation. Do the math.
