# 线与其他几何体的距离

## 直线到直线的距离

计算直线到直线的距离

<div></div>
<ClientOnly>
<distance geo0 = "Line" geo1 = "Line"></distance> 
</ClientOnly>

```javascript
import * as cga from "@xtor/cga.js";
var line0 = new cga.Line(randomV3(), randomV3());
var line1 = new cga.Line(randomV3(), randomV3());
var result = line0.distanceLine(line1);
```

## 直线到射线的距离

计算直线到射线的距离

<div></div>
<ClientOnly>
<distance geo0 = "Line" geo1 = "Ray"></distance> 
</ClientOnly>

```javascript
import * as cga from "@xtor/cga.js";
var line1 = new cga.Line(randomV3(), randomV3());
var ray = new cga.Ray(randomV3(), randomV3().normalize());
var result = line.distanceRay(ray);
```

## 直线到线段的距离

计算直线到线段的距离

<div></div>
<ClientOnly>
<distance geo0 = "Line" geo1 = "Segment"></distance> 
</ClientOnly>

```javascript
import * as cga from "@xtor/cga.js";
var line1 = new cga.Line(randomV3(), randomV3());
var segment = new cga.Segment(randomV3(), randomV3());
var result = line.distanceSegment(segment);
```

## 直线到三角形的距离

var line1 = new cga.Line(randomV3(), randomV3());
var triangle = new cga.Triangle(randomV3(), randomV3()，randomV3());
var result = line.distanceTriangle(triangle);
```
