FOTD 23-11-02 (Fiery Terraces [5])
by Jim Muth 23 Nov '02

23 Nov '02

FOTD -- November 23, 3002 (Rating 5) Fractal visionaries and enthusiasts: The fractal adventures today are still taking place in the giant claw, this time on the biting edge of the upper claw, where, a short distance inland, I found a two-way symmetry which told me that a Mandelbrot atom was near. Often, these surface symmetries lead to what I call 'dry lakes', where the symmetry ends in a blank, but in this case, a midget was indeed waiting at the bottom of the pit. It's not an outstanding midget, only an average one, with most of the impact coming from the strong color palette. Instead of coloring the outside with the normal equal-iteration bands, I have colored it with the < tdis > option, which creates the fiery terraces surrounding the midget, and explains the name "Fiery Terraces". I have already described the image as average, and that is the way I rated it. The time from parameter file to finished image is 8 minutes on my aging P200 machine. The time required to download the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> is less than half the render time. The dense fog early Friday lifted by late morning, leading to a cloudy day with occasional sprinkles of rain. The temperature of 49F 9.5C was not enough to make up for the wet grass, leaving the fractal cats with a boring indoor day. A mid-afternoon treat of turkey eased their irritation, but the day was not yet finished. A high wind arose at nightfall, which insured a skittish evening. As for me, I've got a bit of work to do before taking it easy for the rest of the day. I'm departing now, but I'll be back in 24 hours with another (hopefully) awe-inspiring fractal from the great beyond (wherever that is). Until that glorious moment, take care, and what's wrong with the philofractal list?

It is largely determined by the wave length of the light striking the retina of the eye. But the situation is not so simple. The sensation of color can also be produced by a white light that flickers on and off at the proper rate. I have seen strong color by staring at a white sky through the blades of a rotating exhaust fan. And we have all seen those disks with black and white patterns on them that create the impression of color when spun at the proper rate. In these cases, the color most certainly exists only in the mind. Jim M.

I think I figured out what is going on here. John's messages are coming through (to me, anyway) as UU encoded. This is a method of encoding binary files using only letters and numbers so they can be sent via text-based email. I ran it through an old DOS UU decoder and it came through fine. John, is there a setting in your email program that might be doing this? I'm probably the only person having problems because I'm using the Lotus Notes email client, which is absolutely the worst email program in the world. Most likely, all other email programs recognize UU encoded messages and automatically decode them. Nick

Re: (fractint) Spanky Fractal Database

Hi Damien, Noel Giffin here. I have had to move the rsync server for the spanky fractal database to a new machine. I've set up the identical server and access rights on the eclipse.triumf.ca 142.90.112.35 ip-node. When you have a little time, could you switch over to this one and cancel the rsync calls to sundog.triumf.ca. That node will disappear behind a firewall in a week or so. Cheers, Noel

FOTD 22-11-02 (Forever Amber [6])
by Jim Muth 22 Nov '02

22 Nov '02

FOTD -- November 22, 2002 (Rating 6) Fractal visionaries and enthusiasts: I've seen the topic of the nature of color being tossed around on the Fractint list lately. One of the questions being discussed is whether the sensation one person experiences when he observes red is identical to the sensation someone else experiences when he observes the same bundle of wave lengths. When I ponder this question, the topic of artistic painting (and fractals) comes immediately to mind. Different people always have different opinions of the same work of art (or the same fractal). Could this be because they actually experience the colors differently? The sensation that is red to one person might appear as blue to another person, (though he would consider it red), while to a third person, the first person's sensation of red might be totally unknown. Perhaps different people actually experience the same work of visual art in different ways, and what is pleasing to one person is truly disgusting to another. There is an old saying that goes, "beauty is in the eye of the beholder". This might be more true than we realize. And could the same thing also be true of the non-visual arts such as music and literature? Another question also comes to mind, this one also of a philo- sophical nature. Since the sensation of colors we see in the world around us does not appear until the information from without reaches the mind, what do the actual external objects actually look like? We cannot say they look like a black-and- white photograph, since shades of gray are also color sensations that arise in the mind. We can only dismiss the question as a meaningless waste of energy, saying that the actual shades and colors of the outer world is an abstract something that we can never know, and try to be satisfied with the non-answer. It is far more convenient to project the inner sensation of color onto the outer world and consider color to be an objective reality. But I can never forget that by doing this we are merely fooling ourselves. Today's fractal rates a 6, and that's in my opinion. I enjoy the color amber. Someone who does not enjoy amber might experience amber as puce, and rate the image at only a 3. The scene is located once again in the giant claw fractal, this time just beyond the shoreline of the largest bud in the nascent Mandeloid near the hinge of the claw. I have named the image "Forever Amber", not after a naughty novel that appeared about a half-century ago, but because of the intensely amber network of intertwined filaments surrounding the central midget. With a render time of a little under 6 minutes, the parameter file is a bit slow. The more efficient way of viewing the image is to download it from the web site of Paul at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Heavy clouds and occasional light sprinkles of rain kept things too wet for the dynamic cat duo Thursday. The temperature of 45F 7C failed to help things. As a result, the duo became sulky, and needed several treats to restore their spirits. Today is starting foggy and wet, promising to be little better. I have a bit of work to accomplish before I can think of what kind of treat to give the duo. Until tomorrow, take care, and make a fractal an every-day event.

I have always thought so, based on a mechanistic view of the systems involved. The "normal" human eye has three types of cones with peak sensitivities spaced on the visible spectrum to provide "optimal" human color vision. There are two main types of color blindness: dichromat and shifted trichromat. I don't know if there are many truly color blind (grey scale only) people, and most of these are probably related to brain defect/injury or albinism (complete lack of pigment). Dichromats have only two types of cones, so their internal reconstruction of colors is substantially less sensitive. Shifted trichromats have one or more types with peak sensitivities shifted so that two are closer together on the spectrum, and consequently provide less resolution in that part of the spectrum. (The cones are sensitive to bell-curve distributions rather than discrete wavelengths, which is how we perceive colors between and beyond the peaks.) Severity of degradation varies with the amount of frequency shift. I have a mild case of red/green color blindness, which means my low energy sensors are closer together than normal; but I have absolutely no trouble with anything other than the really subtle color test cards. I have done my share of resistor color code reading, have properly balanced photographic color prints, and am able to discern the difference between copper and gold. Since we are, by the nature of our 98+% shared DNA, wired basically identically, one can argue that our optico-neural wiring, and hence function, is basically the same. In mammals, certain functions such as clear stereographic vision and motion detection require sensory stimulation to train (rewire) the neural net in the visual area of the occipital lobe. But I see no reason to doubt that color vision is hard-wired from the start.

But it does not describe the creation of color. It describes how the *frequency* of electromagnetic radiation in the visual range is affected by relativistic effects in atoms. Color itself is a subjective sensation in the mind. It does not exist until the radiation reaches the mind via the eyes, optic nerve, and visual cortex. Jim (always subjective) Muth
