领导:阿仁,有个很重要的任务需要你去执行。
阿仁:什么任务这么重要?
领导:最近我们有个新园区开张,还请了一个写手写了篇软文来炒作,《云破月来花弄影-SVG多种技术组合实现》,可惜这个写手除了长得帅,文章一点都不好,根本没有阅读量,所以决定派你卧底去这个园区,打探一下。
阿仁:这个园区有啥问题吗,是有黑帮在那里做交易,还是有境外势力在那边有基地?
领导:比这些重要。主要是园区人气太差,希望你假扮一个游客,帮忙了解下其他游客的想法,另外多说说我们园区的好处,鼓动游客参与,活跃气氛。
阿仁:领导,这个工作其实不叫卧底,有个更熟悉的名字
领导:是吗,啥名字?
阿仁:线上这个叫水军,线下叫托儿...
领导:你不愿意去?
阿仁:领导,我堂堂计算机专业毕业,干这个...
领导:请你用十条理由来说服所有的程序员,PHP是世界上最好的语言。
阿仁:领导,你这个园区叫啥名字?
领导:叫SVG园区。

1、啤酒节霓虹灯

阿仁经过一番乔装打扮(主要是换掉了格子衫,背了斜肩的挎包),来到了SVG园区。巧的很,一眼就看到了园区的霓虹灯牌子,正在举办啤酒节。

啤酒节霓虹灯的代码是这样的

对于做霓虹灯的文章,大家可以看我之前的文章《堕落糜烂的光芒-CSS+SVG实现霓虹灯效果》和《亮瞎你的氪金眼-CSS+SVG实现霓虹灯动画》,这里主要讲之前没有用过一些知识点。

css动画效果,通过opacity让啤酒瓶突然消失
@keyframes flicker {
            0% {
                opacity: 0;
            }

            49% {
                opacity: 0;
            }

            50% {
                opacity: 1;
            }

            100% {
                opacity: 1;
            }
        }

......
svg动画效果,通过rotate让啤酒瓶突然倾斜70度
<animateTransform attributeName="transform" id="f1" attributeType='XML' begin='0s;t1.end' dur='2s'
                        type="rotate" from="0 0 0" to="0 0 0" />
                    <animateTransform attributeName="transform" id="s1" attributeType='XML' begin='f1.end' dur='0.1s'
                        type="rotate" from="0 64 64" to="70 64 64" />
                    <animateTransform attributeName="transform" id="t1" attributeType='XML' begin='s1.end' dur='2s'
                        type="rotate" from="70 64 64" to="70 64 64" />

 

一般css动画和svg动画都是平滑运动的,但为了展现霓虹灯瞬间切换的效果,我设置了在关键帧突然切换,所以在49%的时候还没有变化,而在50%的时候突然显示,再配合svg的动画效果,在某个时间点快速的旋转一个角度,就造成了啤酒瓶突然切换倒酒的霓虹灯效果。啤酒杯的泡沫出现和消失的原理也是一样的。

“SVG园区啤酒节”则是使用了svg里面的“textPath”

<path id="beerpath" d="M -20.501285,20 A 97.750643,50 0 0 0 175,20" />

先画好一个path,它的实际样子是这样的

“SVG园区啤酒节”就会沿着它的路径排列好,不过排列是从左上角开始的,所以我们用startOffset参数来调整文字起始的位置,最终调整好的代码是

<text id="beerday" fill-opacity="0.4" stroke="white" stroke-width="1" fill="none" font-size="25">
                <textPath xlink:href="#beerpath" startOffset="40">SVG园区啤酒节</textPath>
            </text>

调整位置还有一种方法,就是修改text的坐标,给text的x设置一个数值也能够调整文字的位置

<text id="beerday" fill-opacity="0.4" stroke="white" stroke-width="1" fill="none" font-size="25" x="40">
                <textPath xlink:href="#beerpath" >SVG园区啤酒节</textPath>
            </text>

这块单独的效果,可以在这里在线看到:请看

2、WC标识

阿仁为了完成领导的任务,带头喝起了啤酒,炒热了游客的气氛,在啤酒节气氛达到最高潮的时候,阿仁突然感觉到了啤酒的反扑,尿意汹涌的铺了上来,远处正好有堵墙,上面写着WC的标志,阿仁扶着墙踉跄的走了过去。

为了做旧,我把WC做了了处理,让标识显的残破,代码如下:

<svg id="wc" t="1565534122398" class="icon" viewBox="0 0 1024 1024" version="1.1"
                xmlns="http://www.w3.org/2000/svg" p-id="5989" width="32" height="32">
                <path stroke="black" stroke-width="25" stroke-dasharray="910,324"
                    d="M326.8 408.7c-22.1 79.5-44.2 159-66.2 238.6-16.4 59.3-16.3 59.3-83.6 54.6C143.9 577.3 110.4 451.4 75.9 322h62.4c23.5 103.4 47.1 206.8 72.4 318.2 21.7-82 41.5-156.9 61.3-231.9 3.2-12 5.9-24 9-36 14.5-55.6 14.5-55.6 78.6-50.3 27.7 104.2 55.7 209.8 86.4 325.6 22.1-100.7 41.5-190.7 61.7-280.5 11.3-50.6 11.8-50.5 71.3-44.3-33.6 126.6-66.9 252.3-100 377-61.1 9.4-61 9.3-75.5-44.8-22-82.1-44.3-164.1-66.4-246.1-3.4 0-6.8-0.1-10.3-0.2zM170 278.5h-53.6c0-46.7-3.7-92.5 1.1-137.4 4.3-39.7 41.2-69.9 81.3-75.9 15.8-2.4 32.1-3.1 48.1-3.2 180.8-0.2 361.7-0.3 542.5-0.1 99 0.2 134.1 35.7 134.1 134.4v82.1h-57.1c0-31.9 0.5-62.5-0.1-93-0.9-47.1-16.4-63.7-62-63.8-190.7-0.4-381.5-0.4-572.2 0-45.5 0.1-61.2 17-62 63.8-0.5 29.6-0.1 59.2-0.1 93.1zM112.9 745.1H170c0 31.9-0.4 62.5 0.1 93 0.8 46.8 16.5 63.8 62 63.9 190.7 0.4 381.5 0.4 572.2 0 45.6-0.1 61-16.7 62.2-63.8 0.7-28.4 0.9-56.9 1.4-85.3 0-1.2 0.7-2.3 2.1-6.4h50.1c0 45.3 3.6 91.1-1.1 136-4.1 39.4-41 69.8-81.4 75.9-17.1 2.6-34.5 3.2-51.8 3.2-178.3 0.2-356.7 0.3-535 0.1-103.9-0.1-137.8-34.3-137.8-138.2-0.1-25.7-0.1-51.4-0.1-78.4zM898.7 569.2c17.5 4.3 33.8 8.3 49.7 12.1-0.4 59.4-46.1 111.1-109.8 122.9-69.4 12.9-136.4 4.5-183.4-52.5-54.9-66.7-58.1-145.2-30.2-224.9 24.4-69.7 86.5-111.7 163.1-113.3 73.7-1.6 131.3 37.8 162 114.1-17.4 4.9-34.3 9.7-53.3 15-3.4-5.6-7-10.2-9.3-15.4-17.7-40.5-49.7-62.6-92.7-63.2-45.9-0.7-80.6 23-101.2 63.9-27 53.7-29.5 109.2-6.7 165.2 18.2 44.9 57.7 73 102.2 73.4 45.3 0.4 81.7-26.5 100.5-74.5 2.6-6.6 5.3-13.3 9.1-22.8z"
                    p-id="5990" fill="none"></path>
            </svg>

主要是用stroke-dasharray,具体的看这里

另外一个残破的对象是那个手指的标识,为了体现没固定好,在风中摇摆的样子,用了动画效果,代码如下:

<use id="finger" xlink:href="#finger">
                    <animateTransform attributeName="transform" id="first1" begin="0s;second1.end" dur="0.5s"
                        type="rotate" from="80" to="100"></animateTransform>
                    <animateTransform attributeName="transform" id="second1" begin="first1.end" dur="0.8s" type="rotate"
                        from="100" to="80"></animateTransform>
                </use>

这个用的animateTransform。在svg的动画里面,核心是三剑客:animate,animateTransform和animateMotion;

  • animate主要用于元素数值属性的变化,比如width,height和颜色啥的
  • animateTransform主要用于元素变换属性的变化,主要和Transform属性搭配,做一些放大缩小,斜切旋转的变化,这个例子就是用于旋转(rotate)的
  • animateMotion主要做路径变化,下面有案例会详细讲。

3、尿意浓

阿仁被WC的标志搞糊涂了,不知道这个手指箭头的意思,看着这个晃悠的指向地面的手指,他恍然大悟,原来这是个露天厕所,指示牌的意思是让他就在这里解决,下体的告急已经不容他多想,他解开了拉链...

这个其实我最先想的是用之前在《天边一朵云-徒手用html生成一朵云,很真的那种》里面用到的filter组合,feTurbulence+feDisplacementMap,它们通过噪点,扭曲变形来改变图形,但是效果嘛,一言难尽啊。这是原始的尿路图:

 

是我在inkscap工具里一挥而就的,一看就是有生活经验的人画出来的,这个弧度,这个波浪感,没有几十年站着尿尿的经验怎么可能做到。然后就用filter加animate效果做出来了第一版


<filter id="filter-suibian" width="350%" height="250%" x="-100%" y="-100%">
                    <feTurbulence type="fractalNoise" baseFrequency="0.015" numOctaves="1" seed="1" />
                    <feDisplacementMap in="SourceGraphic" scale="0">
                        <animate attributeName="scale" id="first2" begin="0s;second2.end" from="5" to="15" dur="0.5s">
                        </animate>
                        <animate attributeName="scale" id="second2" begin="first2.end" from="15" to="5" dur="1s"></animate>
                    </feDisplacementMap>
                </filter>
...
        <use xlink:href="#suibian" filter="url(#filter-suibian)"/>

最终效果如下:

这个效果相当的诡异,看的久了,感觉我还是需要去广州男子医院去一趟,解决下泌尿科的问题,在下半身的强烈不适下,我放弃了,决定上第二版。

<filter id="shock2">
                <feTurbulence type="fractalNoise" baseFrequency="0.1" numOctaves="1" seed="2" result="noise" id="noise">
                    <animate attributeType="XML" attributeName="seed" from="2" to="120" dur="10s"
                        repeatCount="indefinite" />
                </feTurbulence>
                <feMorphology id="morph3" in="SourceGraphic" operator="dilate" radius="1" result="morph1" />
                <feMorphology id="morph4" in="morph1" operator="erode" radius="1" result="morph2" />
                <feComposite operator="out" in="morph2" in2="morph1" result="strokeText" />
                <feDisplacementMap xChannelSelector="R" yChannelSelector="G" in="strokeText" in2="noise"
                    result="displacementMap" color-interpolation-filters="auto" scale="10" />
                <feGaussianBlur stdDeviation="1" result="coloredBlur" />
                <feMerge>
                    <feMergeNode in="coloredBlur" />
                    <feMergeNode in="displacementMap" />
                </feMerge>
            </filter>
<filter id="blur-suibian">
                <feGaussianBlur in="SourceGraphic" stdDeviation="2" />
            </filter>
            <g id="suibian1">
                <use xlink:href="#suibian" width="310"  filter="url(#blur-suibian)" />
            </g>
<use xlink:href="#suibian1" filter="url(#shock2)" />

这个filter的组合,其实不是用在这里的,大家看过我《亮瞎你的氪金眼-CSS+SVG实现霓虹灯动画》文章的人就知道,这个filter是用来做霓虹灯效果的,我再加上一些高斯模糊(feGaussianBlur ),尝试了一下(呸呸,没有尝试)。不试不知道,试过后嘛....

感觉这个至少没有泌尿科的问题,但阿仁的啤酒一定喝的很多,量有点大啊。

4、苍蝇爬呀爬

阿仁终于畅快了,但这不文明的举动也引起了周围环境的变动,一只对骚味很敏感的苍蝇来到了这边,陶醉在这个气味中(是青岛的还是纯生的?)

之前讲过的animateMotion终于要用上了,为了让animateMotion出场,我特地配了只苍蝇,我容易吗?

这是我用inkscap随手画的路线图,再配上一只小小的苍蝇-------就是这只----->,很小哦

这里的path就是上图中画的曲曲折折的图形的svg源码,配合animateMotion就能让苍蝇沿着path的路径走,注意rotate参数,如果不设置成auto的话,苍蝇图片只是沿着path平移,非常的假,看起来是这样的。

这种会倒车的苍蝇显然不是地球上的生物,很容易让阿仁怀疑这里是外星生物的基地,为了打消阿仁的疑心,我决定加上rotate属性。加了rotate=auto就不一样了,图片会沿着path的路径自动调整角度,加了后的效果是这样的

这就显得真实多了。

5、三影

阿仁其实来之前,仔细阅读了那篇《云破月来花弄影-SVG多种技术组合实现》的文章,为了证明他来过,他把流水对准了那棵花...

里故事:上一篇文章说过,云破月来花弄影的作者张先有个外号叫“张三影”。为了致敬他,我凑上了花的影子,阿仁的影子和啤酒瓶的影子,这也是三影...

花影的代码:

<image id="huazhi" xlink:href="huazhi.png" width="100">
                <animateTransform attributeName="transform" id="first" begin="0s;third.end" dur="0.5s" type="rotate"
                    from="0 73 199" to="-5 73 199"></animateTransform>
                <animateTransform attributeName="transform" id="second" begin="first.end" dur="0.2s" type="rotate"
                    from="-5 73 199" to="-7 73 199"></animateTransform>
                <animateTransform attributeName="transform" id="third" begin="second.end" dur="0.4s" type="rotate"
                    from="-7 73 199" to="0 73 199"></animateTransform>
            </image>
            <use id="huazhiyin" xlink:href="#huazhi" filter="url(#huazhishadow)" transform="skewX(29)" />

<use xlink:href="#huazhiyin" x="-225" y="390" />

背影的代码:

<image xlink:href="by.png" x="140" y="368" width="150" filter="url(#blur-moon)" transform="skewX(10)" />

啤酒瓶影子的代码(酒瓶是用svg画的,不是png图)

领导:阿仁啊,听说你在啤酒节上很卖力的炒气氛啊

阿仁:是的,为了能抬高园区的人气,我可是喝了不少,带动了不少人,领导你看还满意吗?

领导:满意,小伙子有前途,不过有个事要你收个尾。

阿仁:啥事啊

领导:园区那边的人说你最后离开啤酒节现场的时候喊了一声‘这一轮我请了’,他们把账单寄过来了。

阿仁:领导,那是我喝多了,不能算啊....
