Lots of fun making images out of sin and cos functions

Shockwave · « **Reply #1 on:** August 01, 2009 »

Really cool, Here's one I made

Code: [Select]

(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 · « **Reply #2 on:** August 01, 2009 »

QUite cool too.

Code: [Select]

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

rbz · « **Reply #3 on:** August 01, 2009 »

Fire effect:

Code: [Select]

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

X marks the spot...

Code: [Select]

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

Amazing fire btw!

Cool stuff.

Shockwave · « **Reply #6 on:** August 01, 2009 »

My own attempt at fire...

Code: [Select]

(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]

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.

Shockwave · « **Reply #9 on:** August 01, 2009 »

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.

va!n · « **Reply #10 on:** August 02, 2009 »

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 · « **Reply #11 on:** August 02, 2009 »

Rgb plasma thing...

Code: [Select]

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

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

benny! · « **Reply #13 on:** August 02, 2009 »

Thats a very cool site indeed.

And cool formulas posted here, too!

spitfire · « **Reply #14 on:** August 02, 2009 »

heres my two

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

va!n · « **Reply #16 on:** August 02, 2009 »

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

Sweet!

va!n · « **Reply #18 on:** August 02, 2009 »

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 · « **Reply #19 on:** August 02, 2009 »

K+

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

Code: [Select]

((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))
