The Black Hole Modofication
by Niekamp 22 Jan '15

22 Jan '15

To emphasize what I have said about fractals and art yesterday I have added one more item to the Black Hole folder: It illustrates the possibilities of artistic modification. All 3 parts are warped independently and separately and can be modified as such: Compression and Function. The compression modifies the color but also the structure, how much depends on the frm used for that part. The function primarily alters the structure but also - to a certain degree - the colors. Which one you use first or both simultaneously is up to you. Anyway the Fractint evolver plays a big part in this game. As it is a single image each modification influences the other parts too, so at the end you have a result that is your own work of art but still is a fractal with all it´s possibilities. It takes some time of course but which work of art is composed in some minutes?

Good News from Dropbox: They have increased the online security - I noticed some days before. To access your account on their homepage you have to sign in, always. If you have an account they need a confirmation of your email address on first visit, just like in a forum. And that is an improvement. So I´m taking the opportunity to release my site again - that means all previous items are available for download, even the images back to 2012, but not the soundfiles. If there is interest I´ll publish a link too. Of course it´s a oneway release. Hopefully I´ll stay secure. Here is the link for the archives: https://www.dropbox.com/sh/rzymsbt18j4fw13/AABG0h4mImmkSKmc0Chqitxla?dl=0 ; The 2015 links remain. ; Petta

The Black Hole
by Niekamp 21 Jan '15

21 Jan '15

now filled....... The latest update which avoids most of the function conflicts has multiplied the already infinite MFR_13 possibilities. The Bugfix 2 days ago has shown that many sofar incompatible MFR_10 and MFR_12 images can now be loaded for modification, so they have multiplied once more. The shaping and coloring possibilities create a lot of space for artistic ideas so in the end you have a mixture of mathematics and art that Jim has talked about. ; A long time ago creative members were the majority of the Fractint users - I miss Lee Skinner - where have they gone? Have they become lazy with age? For me it´s just the opposite - the creation of new and maybe unequaled works keeps you alive and is a thrilling adventure. Of course it´s complicated and needs time to get acquainted with, but learning starts with doing it on a small scale. ; This is an invitation to ask yourself if it is worth the efforts to begin becoming creative again and have an alternative to just sitting on the couch and watching what others accomplish. Think about it. ; The combination is not new but now shows what´s in it! https://www.dropbox.com/sh/xkczlqn8p20rkqq/AABBtpIEL5ERnsOE8G61DisOa?dl=0 ; Petta ; ----------------------------------Start Par------------------------------- 35100-19 { ; Circus Fractalus ; Bees-ManyMods-Secant ; Time 0.03.34.21 Reso 1280/1024 ; ROY map - Shape+Outside warped reset=2004 type=formula formulafile=mfr_13.frm formulaname=multifractal_13 function=sin/cos/exp/sin passes=t center-mag=-46.17554682862955000/-3.31373861156948100/223.8728/1/174.999\ 999999913683/1.21433967048556468e-010 params=-0.05825983458967864/0.3785210730307932/35100.645957671/45235.491\ 1030602/152048.0404808048/24.1604894048/1.00482000594999/256.1000003001/\ 512.1000003001/768.1000003001 float=y maxiter=3071 inside=maxiter outside=tdis periodicity=0 rseed=-2436 colors=000SU0<8>OQ0NQ0NP0MO0<13>EH0DG0DG0<16>350240140<3>010000000<58>X0\ 0X00X00Y00Y00<22>fE0fF0fG0<16>jP0jQ0jQ0jQ0<21>lZ0l_0k_0<4>k`0k`0ka0<17>h\ c0hc0hc0<17>ba0ba0aa0<16>VX0VW0UW0UV0TV0TV0 } 35100-14 { ; The Black Hole ; Bees-ManyMods-Secant ; Time 0.02.01.11 Reso 1280/1024 ; -now filled.

Maya Mandala

This image is the solution for a longtime problem - a conflict between Manymods used as main structure (shape) and the warp effect because they use(d) the same function. It has no influence on generated images but you should replace your version for future images. The result ist striking - judge yourself! The folder is the Round Trip II folder, it uses the same basic image. ; https://www.dropbox.com/sh/f1izwfgpny3kv6a/AABsUBjkycfNpmR0kCg8Rgqha?dl=0 ; Petta ; PS: removed "Rseed=2436" from the par as Jonathan said.

An important practical aspect of anti-aliasing
by Hal Lane 20 Jan '15

20 Jan '15

JackOfTradeZ, et al, I forgot to mention an important practical aspect of anti-aliasing-type image manipulation! If you start with a 256 value color table-type image (like a GIF) and resize it, then if your image manipulation program uses an internal image format the same as that original image (color table-type, for a GIF in my image program) and/or you write out a color table-type image, the results of your anti-aliasing will be quite poor. The 'averaging'/filtering of neighboring pixels' color values during resizing will essentially always result in a color value *not* in the source image's color table. If the resizing algorithm or output image is required to use the original input image's color table colors only, the algorithm can't use its calculated color values that are 'between' the values in that image's color table -- as is necessary to provide anti-aliasing. I work around this problem by first converting my .GIF images to JPG format, and then resizing *these* images down in size to start my anti-aliasing process. The 24 million color format of JPG can then better represent the output of the resizing filter. And I also write out the resulting final resized image in .JPG format to preserve the algorithm's use of the wider range of colors. Note that converting the original input GIFs to the same-sized JPG images retains the identical colors as are in the original GIFs. Also, the JPG 24 million color format gives the ability to represent the needed 'in-between' colors that are not in the original GIF's color table. These 'in-between' colors are created when the averaging/filtering algorithm calculates them during the resizing. I have some more material about anti-aliasing on the bottom of my home page: http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html One of the most important things I figured out about anti-aliasing was this... Excerpt: "One thing that anti-aliasing can do to a fractal is shift the overall brightness of the color of an area that has many single, contrasting pixels in it. Initially, I was unhappy that this happened, since the original colors of the single pixels had been altered, thus shifting the appearance of the area's overall color noticeably. However, on closer investigation I realized that this decrease in contrast of scattered single pixels in an anti-aliased image actually displays the underlying fractal more accurately. Here's why -- quite often the feature in the fractal that's being shown as a single bright pixel is much smaller than that pixel. So, displaying that tiny feature as an entire pixel of that one bright color gives that tiny feature a visual emphasis much greater than it should actually have. As an example, if a feature is in a color that contrasts with that area's background color, and is approximately one tenth the area of a single pixel on the display Â but, by chance that tiny feature is sampled by Fractint Â then that entire pixel would show that contrasting color. The nine tenths of the fractal in the pixel that are of the background color are not seen when this happens. Anti-aliasing adjusts the pixel's color towards the background color, to better reflect the tiny feature's true impact on the pixel that it's displayed in." Another way to say what's going on is: Averaging or filtering a tiny feature's color with its neighbors correctly de-emphasizes that feature. When that tiny feature is displayed as a single pixel, it's being shown as an area much larger than it actually is in the underlying fractal. Note that the single, isolated contrasting pixel color in the original image is not an incorrect color value for that exact location in the fractal. The regularly spaced sampling of the underlying fractal in a raster pattern for each pixel has simply hit a tiny (much smaller than a pixel) bright feature within a larger, darker area by chance. > I made an animation at 2048x2048 recently - 1st time > at that resolution, using the Disk-video mode. > > When I compile the frames to video at lower resolution, > now the video looks much "cleaner" One can choose how many neighboring pixels are used in the resizing used for anti-aliasing. [The factor by which one reduces the size of the image.] It's a personal choice, rather than what's 'correct.' If I recall correctly, different people in this forum use nine, 16 and 25 neighboring pixels -- and different filters. I use 16 neighboring pixels and the Lanczos filter, and I'm pretty happy with my results. This means that I have to calculate my images four times larger in both X and Y to get my 16 pixels, so 4k x 3k pixels will produce a final image of 1k x 768 pixels downsized/filtered by a factor of 4. Note that downward resizing can have a 'softening' effect on the fractal's features due to the removal of high spatial frequencies. I counter this by following my resizing with a *very* slight sharpening of the image. I choose a value that's not visually noticeable, but does remove the original slight fuzziness of the resized image. - Hal Lane ######################## # hallane(a)earthlink.net ######################## --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com

by Hal Lane 20 Jan '15

20 Jan '15

Petta, I was looking forward to the variations on your "The Other Reality" image -- and I was not disappointed. I especially like your 35100-69.GIF -- which is very much like your 35100s49.Gif -- "The Other Reality" image, with a different color map. I may try to make an anti-aliased version of 35100-69.GIF at 1920/1080. In order to not change the aspect ratio of the image and distort the circular figure in the fractal, I'll have to try to adjust the locations of the corners of the image to include a little more area of the fractal on the left and right sides... Wish me luck! - Hal Lane ######################## # hallane(a)earthlink.net ######################## --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com

The rumors are exaggerated!
by Jim Muth 20 Jan '15

20 Jan '15

Fractal visionaries and enthusiasts: The rumors of my departure are grossly exaggerated! Though the world situation grows more discouraging and disgusting, it seems every day, the fractals and I are still here at FC, along with FL. Since the last FOTD was posted, I have found a couple fractal images marginally worth posting to the list, which I might pass along in a couple days. But my energies are now turning to creating images the old way, without a computer. My hand drawing and coloring skills have grown stale in the past 20 or so years I have produced art on computers, but they are not gone, merely sleeping. And my ideas are richer than ever. Hopefully, I will soon be creating real creative fractal art, a combination of fractals and hand drawn scenes. There is still much to be worked out, so stay tuned to see how things develop. Meanwhile, the trio of fractal cats is getting along fine. Until next time, take care, and where did that bright side go? JIM
