You could 'raytrace' from the points to the centre of a sphere and then project the intersections with the sphere onto a plane to give a 'human eye' view sort of thing. Your framerates would drop to less than 1.

(I use raytrace in inverted commas since I've always called that solving a vector equation or finding a point of intersection, but raytracing seems to be the accepted term in the world of computers)


Also, in a way, you are promoting math as the knowledge of coolness. Now that IS magic! RESPECT^2
Does that make me cool because I am doing a maths degree and can do things in my head that most people would need a sheet of paper and a calculator for?

Definetly!!! Now that world can see that math is useful for creating fancy plots correlated to the music of their choice, it will not take long before girls will prefer mathematicians before physicians (med. doctors).

/Spetz - Very cool (M.Sc. Eng. Phys.)

PS. How cool is a M.Sc. that missed to discover the x/z=x2/1 relation? 🙂 DS.

Wow, I'm going for an MSci at the moment, in maths.

I see maths everywhere, it is used everywhere. Personally I think that the coolness of maths isn't just visible in AVS, or computer programming in general, but the fact that it is built into the human brain, into nature and into the things that we construct.

Take a look at anything and there is some maths present. Right angles, pi, root 2, phi, e, etc... These numbers crop up in everything, from A4 paper to the pyramids. In fact the ratio of the sides of a sheet of A4 paper is the same as the ratio of the sides of the rectangular rock surface on which the pyramids were constructed.

'Everything around us can be represented and understood through numbers'. That is because mathematics was created to help us to understand the universe, and to define its fundamental laws, to bring simplicity to the chaotic real world around us and make it easier to explain.

hehehe im a freashmen in high school i dont even get math till next term witch sux i love math and im pretty shure i wont get algrabra 1
then cause im in sbh for my opisitional diffient dissorder and socil angcity dissorder i cant handel the regular classes caus there is far to many people (about thirty) but i read books like the lord of the rings and the silmarilion witch i can follow better than most adults
but i we work on the soler system in sience bah i learnd about that in 3rd grade but unlike the others in my class i memorized it the first time i heard it cause it was cool but the people in my class can hardly read they dont read on site they over use phonics and have 30-50 word vocabs(<-- they probly cant define vocabularey much less say it).


Whoops ultimate run on sentance there not my best spelling either!
I tend to ramble on the net since i hate being in the near people (see above) much less vocalising with them.LOL,well i didnt memorize my times tables but i loze my math but our suck school has only 4 periods a day and i didnt get to pick my electives (they were chosen for me by my counsoler) since i missed the registration day cause my father was killed one week before school(god i miss him)


Whoops there i did it again well i guese i better press submit befor i start again (oww carple tunnel).

Actually, most people's subconcious is way smarter than the concious mind. It does things extremly complex very quickly, yet there is no direct communication towards the concious mind. Like for example, if you imagine an object and rotate it, your mind is doing all the 3D stuff and all you see is the picture created, not the numbers behind it. We can imagine huge, complex, atomically-accurate worlds and universes, yet we can barely divide 2 floating point numbers by thinking.

The mind works in mysterious ways...
jheriko#
In computer terms I think that the best way to explain the complex maths that the brain does to do day to day things (like depth perpception) is that it is hard-wired into the brain, but there is no hard wired division because it isn't a brain function which evolution favoured during our development. As a result we have to do 'software' maths to do division, our minds partly act as emulators to do things like maths using other functions, like memory and logic, which are hard-wired, resulting in a slower performance. It's like using software rendering to run Quake II because you don't have a 3D accelerator card, the brain doesn't have any simple maths acceleration built in to it.
Zevensoft#
I'd say it's more like having hardware acceleration built-in, but not knowing how to access it, and resorting to software methods.

Hehe, taking a step further! 🙂

New DM: T goes to a constant of about 0.8, a better line would be something like this (this is just random-ness):
frame:
t1=t1+0.06;
t=1.1*sin(t1);
t2=t*cos(pow(t1,P=1.2));
beat:
t1=t1-1;
pixel:
d=(asin(1.05*d)-sigmoid(t2,t))/2;
Atero, I took the liberty to take a closer look on parts of the iterative function above. The variable t2 doesn't just oscilates. Because of the power term P="1.2" not being equal to "1" it has changing (over time) spectral signature. It is slightly noticible for values of "1.2", but higher values will change the spectral signature more rapidly. Try the matlab code below (if you have matlab, hehe):
--------------------------------------------------------
clear all;
t=0; t1=0; t2=0; i=1; P=1.6

t=t+0.06;
t1=1.1*sin(t);
t2=t1*cos(t^P);
while (i < 16384),

t(i+1)=t(i)+0.06;
t1(i+1)=1.1*sin(t(i));
t2(i+1)=t1(i)*cos(t(i)^P);

i=i+1; %simulating beat, mod(i,40) approximates 60 bmp
if mod(i,40)==0
t=t-1;
end

end

figure; plot(t);
figure; plot(t1);
figure; plot(t2);

f1=fft(t2(1: (end/2)));
figure; plot(abs(f1(1:end)));

f2=fft(t2(end/2:end));
figure; plot(abs(f2(1:end)));

f3=fft(t2);
figure; plot(abs(f3));

sound(t2);
----------------------------------------------

Try to set P to 1, 1.2, ..., 1.6, ..., 2.0. You can even listen to t2, if you don't want to do the fft-transform. Keep the loop spining 2^n (2^13 = 8192) times, then the fft runs faster, but you probably know that.
When P is 1, you have 1 harmonic in the t2, when t is increased t2 stops having a constant harmonic but becomes spectraly non-constant, t2 gets different spectral signatures depending when in time the spectra is estimated, just listen to t2 🙂

Yes, especially since I don't have matlab. Besides, note the comment 'just random blah-ness,' meaning it was random coding (much like what you see in 'i don't know what i'm doing but i guess if i look confusing i can look cool' presets 😉 )


Still no one comments on how uber-1337 my spiral is 😛

Atero,

your spiral is uber!!!

Yes, especially since I don't have matlab.

Why haven't you pulled the plug yet? Life is nothing with out matlab, pitty it (MATLAB 5.1) crashes on my XP-mashine all the time. (Any one: can I fix that in some way, or do I need newer MATLAB?)

LOL, there are lot of dudes out there having those lines above as their principal design mantra when making new presets... Our presets may be ugly, at least (we think) we know what we are doing 🙂

i TOTALLY concur w/ spetz

its such a rush to see what you wanted to happen happinging

even if the presets look stupid.

chain reaction...

Older windows = WIN98 ---> WIN98 = constant crashes ---> constant crashes = unworkable system ---> unworkable system = no fun using the PC 😢
dirkdeftly#
Win98 is more stable than XP, and much more useable, unless you're a goddamn techie that needs everything to be the newest no matter how much better the old versions are *cough* WA3 *cough*
jheriko#
Windows 2000 is far and away the most stable windows version ever. I've had zero crashes since using windows 2000, no more illegal operations and fatal errors. The worst that happens is that the software crashes, my screen goes blank and deals with it for a second or two then Win2K resumes its normal operation with all of my other apps none the wiser.

Win2K rocks my world.

Hi,

win98 is a joke... Sorry... refuses to shutdown, hangs, acts strange etc. Win2K is good but I had problems running couple of games I have (gta3-total crashes pc, nhl2002-graphical issues, etc) so I switched to XP, everything works now (except that winamp crushes sometimes when I run avs, MATLAB crashes and some flash heavy sites on the net crash on me too.) 🙂 However I have found XP coolest so I stick with it.

The preset is alright but a spiral isn't technically impressing and you should use a perspective projection for your 3d code, it makes it look more far more 3 dimensional. Something like:



x=x1/(1+z1*0.5);

x=y1/(1+z1*0.5);
If you want to see some really awesome avs (and rip them apart to learn, but don't steal code) here are some eye-bleeders, and there are plenty more out there too.

Nice selection, UnConeD, Duo, EL-VIS, AVS-King, Danjoe, You and me! 😁 Thanks for including my pack.

I had to include you skupers, a lot of your presets are really cool. You have a much better grasp of dynamic movement than a lot of other artists have. (Personally I hate DM cos I haven't mastered it to a similar degree as my favorite artists yet)

Well then it was your comp, not the OS. You weren't by any chance using a Compaq? 😉

GTA3 is a joke. If I was making a computer game and it got into the same state as that, I wouldn't release it. Anyone who makes a game which doesn't use OpenGL or at least D3D for its graphics is asking for trouble, thats why GTA3 runs like a pile of dog crap.

Why do game deveolpers insist on releasing games before they are finished and optimised, and why do they do things the hard way if it is only *guaranteed* to make their game much worse?

GTA rocked my world. GTA2 has crap graphics but was fun. GTA3 was a cool idea but was made far too late and it was far to unfinished and unprofessionally made.

No, I never buy branded computers from compaq, HP, siemens, fujutsu, IMB etc. Poor expansion possibilities, less value, non-standard solutions, etc. They are allt b.s. products. I have built my own pc, and it is stable with hours of 3d-gaming with out the slightest error or crash. I have a p4-1.8Ghz (1800/100/400), but I am running it OCed @ 2400/133(memory @ 178)/533. 🙂

Intel build their processors to safely run at 137% of the stated clock speed. You could still clock it up by another 66MHz 😁
dirkdeftly#
Well that could also be your problem: you fucked up with the installation. In any case it's an isolated problem, 98 doesn't do that if it's properly run, XP still sux, as well as anything other than 98/2k. Of course, MacOS is the BEST, but I'm not going to go into that 😉

Meh. Liunx is not a desktop operating system. To finicky if you want to do anything. I, personally, don't wan't to have to manually recompile my kernal everytime I make a change to my system.

Bah, use Commodore Basic 2.5



load "winamp3.exe",8,1

loading winamp3.exe



ready

I tried installing red hat on three different *REALLY* standard boxes and xwindows worked on none of them under linux. it was the cd that came with 'red hat linux for dummies' and i definately am not a computer dummy, i've built three boxes and made countless utilities and programs and I've never had a problem with windows or unix that I couldn't handle. The only people I know that have got linux running are three really lucky dimwits and a man with a PhD in computer science who spent three entire days forcing it to work.

Now tell me that Linux is more reliable than windows.

Besides Win2K is as stable as a rock. I've been running a win2k adv server for over a year now, i've only had to reformat once and it was for a virus.
