有人用html就写了一朵漂亮的玫瑰,是不是有点太骚气了。纯javascipt就弄出了玫瑰花,再次显示了html5的威力
警告:传说ie6内核是无法看到的,建议用chrome或者firefox。
玫瑰花效果:
实现代码:
复制代码代码如下:
lovevar b = document.body;
var c = document.getelementsbytagname('canvas')[0];
var a = c.getcontext('2d');
document.body.clientwidth;
// start of submission //
with (m = math) c = cos, s = sin, p = pow, r = random; c.width = c.height = f = 500; h = -250; function p(a, b, c) { if (c > 60) return [s(a * 7) * (13 + 5 / (.2 + p(b * 4, 4))) - s(b) * 50, b * f + 50, 625 + c(a * 7) * (13 + 5 / (.2 + p(b * 4, 4))) + b * 400, a * 1 - b / 2, a]; a = a * 2 - 1; b = b * 2 - 1; if (a * a + b * b < 1) { if (c > 37) { n = (j = c & 1) ? 6 : 4; o = .5 / (a + .01) + c(b * 125) * 3 - a * 300; w = b * h; return [o * c(n) + w * s(n) + j * 610 - 390, o * s(n) - w * c(n) + 550 - j * 350, 1180 + c(b + a) * 99 - j * 300, .4 - a * .1 + p(1 - b * b, -h * 6) * .15 - a * b * .4 + c(a + b) / 5 + p(c((o * (a + 1) + (b > 0 ? w : -w)) / 25), 30) * .1 * (1 - b * b), o / 1e3 + .7 - o * w * 3e-6] } if (c > 32) { c = c * 1.16 - .15; o = a * 45 - 20; w = b * b * h; z = o * s(c) + w * c(c) + 620; return [o * c(c) - w * s(c), 28 + c(b * .5) * 99 - b * b * b * 60 - z / 2 - h, z, (b * b * .3 + p((1 - (a * a)), 7) * .15 + .3) * b, b * .7] } o = a * (2 - b) * (80 - c * 2); w = 99 - c(a) * 120 - c(b) * (-h - c * 4.9) + c(p(1 - b, 7)) * 50 + c * 2; z = o * s(c) + w * c(c) + 700; return [o * c(c) - w * s(c), b * 99 - c(p(b, 7)) * 50 - c / 3 - z / 1.35 + 450, z, (1 - b / 1.2) * .9 + a * .1, p((1 - b), 20) / 4 + .05] } } setinterval('for(i=0;i<1e4;i++)if(s=p(r(),r(),i%46/.74)){z=s[2];x=~~(s[0]*f/z-h);y=~~(s[1]*f/z-h);if(!m[q=y*f+x]|m[q]>z)m[q]=z,a.fillstyle="rgb("+~(s[3]*h)+","+~(s[4]*h)+","+~(s[3]*s[3]*-80)+")",a.fillrect(x,y,1,1)}', 0)
