形状层新手教程(三)

形状层的效果器(二)

hello,大家好,这里是形状层新手教程的第三节,这个系列总算要是结束了呢。这节的主要内容有修剪路径、扭曲、摆动路径、摆动变换和Zig zag(真不懂这是什么意思),没看过我第一节第二节的同学可以先去看看。

1.Trim path(修剪路径)

这个效果器算是比较常用的,我们在做各种路径修剪动画会经常用上,类似write on(写入)、stroke(描边)特效,但我个人认为形状层的trim path(修剪路径)用起来会更加舒服,因为他能够和其他效果器配合起来,可以达到相当棒的效果。下面举几个例子吧:

1.1.与Puker&Blot配合。

下面的图形是六边形配合Puker&Blot和修剪路径完成的。

1.2.与merge Path配合

可能很多人在各种地方看到用stroke、3dstroke等特效制作花纹生长的教程,不可否认他们有他们的优势,但是如果利用矢量图形可以转化为形状层的特性,会变得非常的方便。

具体方法有两种,但是最好有illustrator的支持(用于给图形分段,分成一条一条的)

第一种,先画好路径1,然后运用merge path做图形蒙版/布尔(interface交叉),对路径1进行trim path操作;

另外一种直接使用Trim path进行擦除,具体就是同时控制开始位置和结束位置(这里补充一点,如果图形不闭合,会以两个端点连线的范围进行填充)

差点忘记说参数了,其实和Stroke插件和类似,基本上都一样,前面三个参数应该不用讲也知道(起点、结束点、偏移),最后那个参数表示的是“在有多条路径时是选择一起修剪”,或者“一条结束后再接下一条进行修剪”。

顺便补充一下百度到的两个个方法:利用3D stroke 进行制作利用3D stroke 进行制作

2.Twist(扭曲)

这个效果器我研究得也不是很多,用处大概是跟收缩和膨胀一样做出一些意想不到的图形吧。还有就是如果你的图形如果再加上trim path会产生特殊的效果。

具体参数有两个:扭曲的角度和中心点。

3.Wiggle path(抖动路径)

这个效果器能生成复杂的抖动的图,比如上图是就是由一条直线生成的。它是一个动态的效果器,即你不用打关键帧,它也可以随时间摆动。

下面介绍一下参数吧:

3.1.size(大小):调节的是摆动的峰值,数值越高,上下的距离越大

3.2.detail(细节):就是横向的密度

3.3.point(点):有corner选项和smooth选项,用于调节顶点间的平滑程度。

3.4.wiggle/second(摆动/秒):摆动的速度,如果调为0,那么他就不会动。

3.5.correlation(关联性):数值越接近100,越接近原图,100%和原图一样。

3.5.temporal phase(时间相位)具体来干嘛的我也不太清楚,下面的空间相位和随机种子的作用差不多。

3.6.spatial phase(空间相位):和前面时间相位差不多。

3.7.randomseed(随机种子)和粒子的随机种子类似,如果直接复制图层的话,造成和原来的图层不一样是因为这个因素的影响。

4.Wiggle transform(摆动变换)

关于摆动变化,我认为是形状图层中最有趣的效果器之一。如果单单使用wiggle transform你可能并不会对他感冒,就好像在基本图层属性上打上了wiggle表达式的感觉,但是如果加上repeater的话就像变了一张脸,多了很多的变化,下面这张图是我用wiggle transform随便做的,不了解的人还会以为是用粒子做的呢。

接下来先说说参数吧:

4.1.wiggle/second(摆动/秒):每秒振动多少,如果设为0,就不会摆动。

4.2.correlation(关联性):“关联”属性指定一组重复形状内某个重复的形状与其邻居的摆动变换之间的相似程度。仅当“中继器”操作先于“摆动变换”操作发生时,关联才有意义。当“关联”为 100% 时,所有重复的项以相同方式变换;当关联为 0% 时,所有重复的项将分别变换。

4.3.temporal phase(时间相位):当我们觉得wiggle/second的幅度太大,我们可以考虑用这个属性K帧。

4.4.spatial phase(空间相位):和时间相位差不多效果。

4.5.randomseed(随机种子):这个应该不用说明了吧。

再说说wiggle transform的一个用法吧,其实就是聚合动画,我们将摆动变换的特效赋予形状层,在其子集的变换里面一开始将P值调大,最后变化为0。

小贴士:1.我们可以做两层wiggle transform(第一层用来摆放位置(wiggle/second设为0),另一层添加动态效果),这样让我们可以控制得更加自由。

2.我们在做聚合动画时可以考虑分组进行调节,前面的是我随便糊的,可能也不是特别好看。

5.Zig zag

这个效果是作用于线条的,下面是又一条直线演变过来的。可以做出很好看的波浪线。

5.1.size(大小):调节波浪的峰值(最高/最小)

5.2.ridges per segment:用来调节每个峰值的间距。

5.3.points(点):就是折线处是尖的,还是缓的。

我就想为什么不顺便加一个偏移的选项呢(笑)

好的,形状层基础三节就全部讲完了,希望能对你有所帮助

真累啊_(: 」∠)_。
