Lots of fun making images out of sin and cos functions

[Shockwave]

Really cool, Here's one I made

Code Select Expand


(sin(x*y*y)-sin(x*x/y)+(cos(y*y/x)/y)-(x/y))*(sin(x*y*y)-sin(x*x/y))


(View in high quality, it gives a kind of warped chessboard merged with keftales).

[Shockwave]

QUite cool too.

Code Select Expand

x+y/r*sin(g)+(x*y/r*sin(r))

[Rbz]

Fire effect:

Code Select Expand

r*2+g+pow(y/1.8+sin(x),1.0)+(sin(x*1.5)*sin(y))

[Shockwave]

X marks the spot...

Code Select Expand


x+y*3*sin(x/y)


Amazing fire btw!

[rdc]

Cool stuff.

[Shockwave]

My own attempt at fire...

Code Select Expand


(r*3+(x+y)+x*sin((y+90)*pi)-x*cos((y)*pi))-(b*2+(x-y)+x*sin((y+90)*pi)-x*cos((x)*pi))


Diamond shaped atm

texture:

Code Select Expand

r+g*sin(x)+cos(y)*sin((x*y)/pi)

Looks a nifty find.
not to be thick but what are you supposed to do with those formulas?
obviously r,g,b are the colours and I take it, in 0-255.

The formula is explained in the website, you have r,g,b,x,y varialbe to play with and all the trig you can throw at it.

Play with the formulas, if it doesnt evaluate, the site will tell you.

very nice site! have to check how to reproduce it with own code...
here are some results i have created:

sin(x)*64+cos(y)*64

sin(x)*64+cos(y)*32

sin(x)*1

sin(x)*64

sin(x)*64+cos(y)*32+floor(x*y)

r+g*sin(x)+atan(y)*sin((x+y)/pi)

r+g*sin(x)+atan(y)*sin((x+y)/cos(b))

it makes so much fun!

[Shockwave]

Rgb plasma thing...

Code Select Expand

(sin(r+x)*cos(g+y)*atan(b+(x-y)))

[spitfire]

awesome, so when will you guys write a tutorial for me about this stuf f:)

[benny!]

Thats a very cool site indeed.

And cool formulas posted here, too!

[spitfire]

heres my two

I like that you managed to write something on one of them

[va!n]

here is my newest texture for your dreams of confectionery

r+(g/4)*sin(x/4)+atan(y/4)*sin((x+y*b)/cos(b))


next i will try to make a small DBF sign advert there

[benny!]

here is my newest texture for your dreams of confectionery

r+(g/4)*sin(x/4)+atan(y/4)*sin((x+y*b)/cos(b))

Sweet!

[va!n]

Yeah... just a small DBF sign on the site

(1)if((y+6<11.5)and(floor((x)*3)%80,floor((y+10)*2)%80)in((1,1),(1,2),(1,3),(1,4),(1,5),(2,1),(2,5),(3,1),(3,5),(4,2),(4,3),(4,4),(6,1),(6,2),(6,3),(6,4),(6,5),(7,1),(7,5),(8,1),(8,3),(8,5),(9,2),(9,4),(11,1),(11,2),(11,3),(11,4),(11,5),(12,1),(12,3),(13,1),(13,3),(14,1)))else(-1)

Next i will try to combine a texture with this sign

[Shockwave]

K+

Here's my (feeble) attempt with your sign..

Code Select Expand


((1)if((y+6<11.5)and(floor((x)*3)%80,floor((y+10)*2)%80)in((1,1),(1,2),(1,3),(1,4),(1,5),(2,1),(2,5),(3,1),(3,5),(4,2),(4,3),(4,4),(6,1),(6,2),(6,3),(6,4),(6,5),(7,1),(7,5),(8,1),(8,3),(8,5),(9,2),(9,4),(11,1),(11,2),(11,3),(11,4),(11,5),(12,1),(12,3),(13,1),(13,3),(14,1)))else(-1))+(sin(x*y)-cos(x*y*x))
