# 公式与图形 MathTexs and Graphics

```python
ChineseMathTex(*texts, font="SimSun", tex_to_color_map={}, **kwargs)
```

创建中文数学公式。在此函数的公式部分和`tex_to_color_map`中直接写入中文即可，**无需包裹`\text{}`**，返回MathTex。`font`，设置公式中的中文字体。所有原版参数都可使用。

Creates Chinese MathTexs. You can directly write Chinese characters in the formula part of this function and in `tex_to_color_map` **without wrapping them in `\text{}`**. Returns a MathTex mobject. The `font` parameter sets the Chinese font for the formula. All original parameters can be used.

```python
LabelDot(dot_label, dot_pos, label_pos=DOWN, buff=0.1)
```

创建一个带有名字的点，返回带有点和名字的VGroup。`dot_label`，点的名字，字符串。`dot_pos`，点位置`[x,y,z]`。`label_pos`，点的名字相对于点的位置，Manim中的方向向量。`buff`，点的名字与点的间距，数值。

Creates a point with a name. Returns a VGroup containing the point and its name. `dot_label` is the name of the point (a string). `dot_pos` is the position of the point `[x,y,z]`. `label_pos` is the position of the label relative to the point (one of the direction constants in Manim). `buff` is the spacing between the label and the point (a numerical value).

```python
MathTexLine(formula: MathTex, direction=UP, buff=0.5, **kwargs)
MathTexBrace(formula: MathTex, direction=UP, buff=0.5, **kwargs)
MathTexDoublearrow(formula: MathTex, direction=UP, buff=0.5, **kwargs)
```

创建可以标注内容的图形，返回带有图形和标注内容的VGroup。`formula`，标注的公式，MathTex类型。`direction`，标注内容相对于线的位置，Manim中的方向向量。`buff`，标注内容与图形的间距，数值。图形的所有原版参数都可使用。

Creates a graphical annotation for a MathTex mobject. Returns a VGroup containing the graphic and the annotation. `formula` is the MathTex mobject to annotate. `direction` is the position of the annotation relative to the graphic (using Manim's direction constants). `buff` is the spacing between the graphic and the annotation. All original parameters of the underlying graphic can be used.

```python
ExtendedLine(line: Line, extend_distance: float)
```

将一条线延长`extend_distance`的距离，返回延长后的Line。`line`，Line类型。`extend_distance`，要延长的距离，数值。

Extends a line by `extend_distance`. Returns the extended Line. `line` must be of type Line. `extend_distance` is the distance to extend (a numerical value).

# 点 Dots

```python
CircleInt(circle1: Circle, circle2: Circle)
LineArcInt(line: Line, arc: Arc)
LineCircleInt(line: Line, circle: Circle)
LineInt(line1: Line, line2: Line)
```

函数名代表了寻找具体图形交点的功能。例如`LineCircleInt`代表寻找Line和Circle的交点，返回点位置`[x,y,z]`，如果没有交点会返回`None`。

The function names represent the function of finding the intersection points of specific shapes. For example, `LineCircleInt` represents finding the intersection points of Line and Circle. Returns the position of the point `[x,y,z]`. If there are no intersection points, it will return `None`.

```python
TangentPoint(p1, p2, line_start, line_end)
```

计算以两点`p1`和`p2`为圆上的点，且与线段相切的切点坐标，返回切点位置`[x,y,z]`，无法计算则返回None。`p1`和`p2`为圆上的两个点，点位置。`line_start`和`line_end`是线段的起点和终点，点位置。

# 动画 Animation

```python
VisDrawArc(scene: Scene, arc: Arc, axis=OUT, run_time=1)
```

创建可视化（显示半径）的绘弧动画。直接使用即可，**无需写入`self.play()`内**。 `scene`，动画场景。`arc`，已经定义好的Arc。`axis`，只有2个值`IN`和`OUT`，分别表示正方向还是反方向作弧。`run_time`，这是绘弧动画的时长。

Creates a visualized arc drawing animation (with radius display). Can be used directly **without wrapping in `self.play()`.** `scene` refers to the animation scene. `arc` is the predefined Arc mobject. `axis` accepts two values: `IN` (positive direction) and `OUT` (negative direction), indicating the drawing direction of the arc. `run_time` denotes the duration of the arc drawing animation.

```python
self.play(TypeWriter(mobject, interval=2, **kwargs))
```

`TypeWriter`用于实现Text内容的打字机效果（按顺序逐个显示）。`mobject`，必须为Text类型。`interval`，每个字符间的显示间隔时间（单位：秒），数值。`Animation`的其他参数都可使用。

`TypeWriter` is used to achieve a typewriter effect for Text mobject (displaying characters sequentially one by one). `mobject` must be of type Text. `interval` is the time interval (in seconds) between each character's appearance (numeric value). All other parameters from `Animation` can also be used.
