I play with my code all the time to show other designs and motions that can come from it. This piece has been my favorite to remix so far && this pen demonstrates the effect very basic numeric changes can have. So much more can be done beyond this, but below are values that I think are the most fun to play with - without getting too in depth. Over there is a spiral design I made using this pen...
The x value on line 23 is controlling size,
so we'll leave that alone and play with y.
We're at line 24:
y = x * Math.sin(i +
l
* t + x / 50) /
m
;
Playful
l and m
are going to effect speed, angles && movement; the results of which are heavily influenced by line 34. Current values are shown; you may input new values below.
*/
...(i +
...x / 50) /
;
/*
b
is important, it's used in lines 25 && 26 to manipulate our _x, _y points. We define its value at line 34, where the real magic is:
b = ( j *
n
) * Math.PI /
o
;
j = loop counter from line 21 which we are multiplying by
n
; consider
n
our theta value. You can use
any
number.
*/
( j *
)
/*
o = our pi divider. We're going to muliply the result of ( j*
n
) by Math.PI, divided by some number
o
.
You don't have to "know" what number to divide by.
Play with it.
*/
Math.PI /
/*
Bonus:
var
i
= num of layers. We use this as a counter on line 17:
(var i = 0; i <
k
; i++)
We want i to be less than some number
k
. Best results between .1 && 5
*/
i <
;
/*
Bonus 2: You can adjust the width of the lines by entering a value for var
lw
on line 20:
$.lineWidth =
lw
;
Keep in mind that we are using the stroke(), which tends to hurt performance; sacrificing perf for width/line thickness. Keeping it below 2 is generally safe.
*/
$.lineWidth =
;
/*
Bonus 3: We have little circles at the meeting of each angle. We can adjust the size of them by editing var
r
within the arc() on line 34. For no circles, enter 0:
$.arc(w / 2 + _x, h / 2 + _y,
r
, 0, 2 * Math.PI);
*/
$.arc(... + _y,
, ...);
/*
Bonus 4: May as well mess with the color alpha; .01 to 1, line 22.
$.strokeStyle = 'hsla('+(u*2)+',100%,60%,'+
a
+')';
u
= our color update var; init @ 0 && incremented on line 40. We'll just play with the alpha value
a
.
