indoor3D
====
This is a javascript lib based on three.js to show an indoor map.
**This was an experimental project when I was learning javascript and webgl, and I haven't updated it since then.**
**Thanks for the followers and feedbacks, I decide to update it again.**
**A GUI map eidtor written by QT is under development. And I'm working on supporting the popular GeoJson format**
# Demo #
2D Map Demo Page: http://wolfwind521.github.io/2dmap
3D Map Demo Page: http://wolfwind521.github.io
# Usage #
a simplest example:
```html
var map = new IndoorMap();
map.load('data/testMapData.json').showFloor(1);
```
a little more complex example：
```html
var params = {
mapDiv:"indoor3d",
dim:"3d"
}
var map = IndoorMap(params);
map.load('data/testMapData.json', function(){
map.showAllFloors().showAreaNames(true).setSelectable(true);
var ul = IndoorMap.getUI(map);
document.body.appendChild(ul);
});
```
The explanation is as follows:
1) include the required js files
```html
```
- [three.min.js](http://threejs.org/): a 3D javascript library
- Detector: detects whether the browser support the webgl. if it does not, threejs switches to a normal canvas renderer.
- OrbitControls: handles the user interactions to zoom, pan and pivot. (Only used in 3D version)
- Projector: user selection detection used by threejs. (Only used in 3D version)
2) set up the parameters of the indoor map and pass it to the creator
```js
var params={mapDiv:"indoor3d",dim:"3d"};
var indoorMap = IndoorMap(params);
```
optional parameters:\
@mapDiv: if you have create your own ```
``` as a map container, you can specify its id here, otherwise it will create a full screen map.\
@dim: "2d" or "3d". "3d" as default value. But the final result depends on your device. If it doesn't support WebGL, it will show a 2d map even if u set "3d".
So if there is no params passed to IndoorMap, it will create a fullscreen 3D map by default:
```js
var indoorMap = IndoorMap();
```
3) load the map data, and set up its styles.
```js
indoorMap.load('data/testMapData.json', function(){
map.setTheme(myTheme).showAllFloors().showAreaNames(true).setSelectable(true);
var ul = IndoorMap.getUI(indoorMap);
document.body.appendChild(ul);
});
```
the second parameter of the load() function is a callback function when the data is successfully loaded.
You can customize the style and interaction of your indoor map in it. You may call the functions separately:
```js
map.setTheme(myTheme);
map.showAllFloors();
map.showAreaNames(true);
map.setSelectable(true);
```
or in a chain for convenience:
```js
map.setTheme(myTheme).showAllFloors().showAreaNames(true).setSelectable(true);
```
The UI is the buttons for switching floors. Its style is defined in the css file. so you can customize it by yourself.
# User Reference #
There are Three main classes:\
-IndoorMap\
-IndoorMap2d\
-IndoorMap3d
## IndoorMap2d ##
### methods: ###
**.load(fileName, callback)**
loads a file.
When it finishes loading, the callback functon is called.
Since the ui can only be constructed after the data is fully loaded, so the `getUI()` function must be called in the callback.
if the file is already loaded by other modules, you should use the `.parse(jsonData)` method instead
**.parse(jsonData)**
parse the json Data.
if the jsonData is loaded by other modules, you can just use this function to pass it to the indoor map
**.setDefaultView()**
reset the camera to default view (Default perspective view for a 3d map and default top view for a 2d map)
**.setTopView()**
set the camera to the top view. this function is only valid in the 3d map.
**.zoomIn(zoomScale)**
zoom in. zoom Scale is not necessary. so you can just call .zoomIn()
**.zoomOut(zoomScale)**
zoom out. Same as the zoomIn() function, zoom Scale is not necessary.
**.adjustCamera**
Resets the camera to its default settings. This function is called when switching floors
**.setSelectable(selectable)**
selectable- a boolean parameter to specify whether the rooms are selectable
**.showLabels(showLabels)**
showLabels- a boolean parameter to specify whether to show the labels.
The labels are the icons and texts in the map.
**.getUI()**
returns a `
` tag with all the floor id. The user can switch the floor by clicking the `- `
You can insert the `` to anywhere in the html.
Make sure to call this method only after the map is loaded.
**.setSelectionListener(callback)**
set the call back function when a shop is selected.
the shop id is passed as the parameter of callback. and -1 for nothing is selected.
**.getSelectedId()**
get the selected shop's id
**.selectById(id)**
select the shop by its id
**.showFloor(id)**
`id`-the floor id
shows the floor by id. Notice this does not handle the labels.
**.showAllFloors()**
shows all the floors together. Notice this does not handle the labels.
## Mall: ##
### Properties ###
**.floors**
This is an array with all the floors of `[THREE.Object3D]`(http://threejs.org/docs/#Reference/Core/Object3D) type.
### Methods: ###
**.getCurFloorId()**
gets the `id` of the current floor.
Notice: the `id` is a signed integers. -1 means Floor B1, and 1 means Floor F1. 0 is preserved for showing all the floors.
**.getFloor(id)**
`id`-the floor id
gets the floor of `[THREE.Object3D]`(http://threejs.org/docs/#Reference/Core/Object3D) type by its `id`.
**.getCurFloor()**
gets the current floor of `[THREE.Object3D]`(http://threejs.org/docs/#Reference/Core/Object3D) type.
