探花 91 TikZ animate 合营制作基础函数动画

与 TikZ 合营制作动画,不错使用 animate 宏包。animate 宏包不错用于生成 JavaScript 动画探花 91,而 TikZ 不错用于生成矢量图形。

要使用 animate 宏包与 TikZ 合营制作动画,需要先在导言区中引入 animate 宏包和 TikZ 宏包:

\usepackage{animate}\usepackage{tikz}

然后,不错使用 animate 号召来创建动画。animate 号召的参数阐述如下:

file:动画的文献名。start:动画的肇端帧。end:动画的已毕帧。delay:帧之间的延长技巧(以毫秒为单元)。

举例,以下号召将创建一个包含 10 帧的动画,每帧延长 100 毫秒:

\animategraphics[delay=100]{image.pdf}{1}{10}

要使用 TikZ 在动画中生成矢量图形,需要在 animate 号召中指定图形的参数。举例,以下号召将在动画的第一帧中绘图一个红色的圆形,在第二帧中绘图一个绿色的圆形,在第三帧中绘图一个蓝色的圆形:

\animategraphics[delay=100]{image.pdf}{1}{3}{ { \draw[red,circle] (0,0) circle (1cm); }, { \draw[green,circle] (0,0) circle (1cm); }, { \draw[blue,circle] (0,0) circle (1cm); }}

animate 宏包提供了很多选项来抑制动画的后果。这些选项不错在 animate 号召中指定,也不错在宏包的选项中指定。

以下是一些常用的选项:

autoplay:动画是否自动播放。loop:动画是否轮回播放。controls:是否露出抑制按钮。posterframe:动画的预览帧。

举例,以下号召将创建一个自动播放、轮回播放、露出抑制按钮的动画,并将肇端帧建造为 5:

\animategraphics[autoplay,loop,controls]{image.pdf}{5}{10}

以下是一些使用 animate 宏包与 TikZ 合营制作动画的示例:

物体剖析:不错使用 TikZ 绘图物体,并使用 animate 宏包抑制物体的剖析。举例,不错绘图一个球,并使用 animate 宏包抑制球的迁移。局势变化:不错使用 TikZ 绘图局势,并使用 animate 宏包抑制局势的变化。举例,不错绘图一个矩形,并使用 animate 宏包抑制矩形的大小变化。翰墨动画:不错使用 TikZ 绘图翰墨,并使用 animate 宏包抑制翰墨的动画后果。举例,不错绘图一个字幕,并使用 animate 宏包抑制字幕的改革后果。

animate 宏包不错用于创建多样类型的动画,不错匡助您在 LaTeX 文档中创建天真兴味的动画。
