@0x4d/locationar 中文文档教程
LOCATIONAR
基于简单位置的论证现实库，基于 WebRTC，地理定位，DeviceOrientation 和 AmbientLightSensor
Online Samples:
- Use Chrome
- goto the Compass example and see if it's working [camera is working, north in the right direction]
- goto the Location example and you should see a red cube 10 m in the direction of North
- If you don't see the cube or want to change the position click "InfoPanel" and then you can press the button GetPosition to set the position of the cube to your current position and offset it with the +10N, +10W,… buttons Here you can also see the raw sensor data
Problems/Limentations
- missing compass accurcy[can't find exact numbers, but up to +/- 10° on good devices, on some devices completely unuseable]
- camera fov[different phones have different fov's and if the difference between the camera fov and the set fov is to big, the mapping for non-centered, far away objects will be distorted]
- gps accurcy[can be a problem if the object is nearer than 20 meters]
- to use the light ambient light sensor, you need to set the chrome flag #enable-generic-sensor-extra-classes to enabled
Documentation and Examples
Browser compability
✔️Chrome ❌三星互联网[缩放不起作用] ❌Firefox【无绝对罗盘】 ❌UC[来源无效] ❌歌剧 ❔Safari[无法在苹果设备上测试]
Usage
lib 很小，只有 20KB
LOCATIONAR 作为 npm 模块提供：
npm i @0x4d/locationar
您也可以下载此存储库并导入 dist/LOCATIONAR.js 文件
