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

Usage
a simplest example:
<!DOCTYPE html>
<html>
<body>
<script src="js/three.min.js"></script>
<script src="js/Detector.js"></script>
<script src="js/OrbitControls.js"></script>
<script src="js/IndoorMap.js"></script>
<script src="js/Projector.js"></script>
<script src="js/IndoorMap2d.js"></script>
<script src="js/IndoorMap3d.js"></script>
<script>
var map = new IndoorMap();
map.load('data/testMapData.json').showFloor(1);
</script>
</body>
</html>
a little more complex example：
<!DOCTYPE html>
<html>
<body>
<script src="js/three.min.js"></script>
<script src="js/Detector.js"></script>
<script src="js/OrbitControls.js"></script>
<script src="js/Projector.js"></script>
<script src="js/IndoorMap.js"></script>
<script src="js/IndoorMap2d.js"></script>
<script src="js/IndoorMap3d.js"></script>
<link href="css/indoor3D.css" rel="stylesheet">
<div id="indoor3d" style="width: 800px; height: 500px"></div>
<script>
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);
});
</script>
</body>
</html>
The explanation is as follows:
- include the required js files
<script src="js/three.min.js"></script>
<script src="js/Detector.js"></script>
<script src="js/OrbitControls.js"></script>
<script src="js/Projector.js"></script>
<script src="js/IndoorMap.js"></script>
<script src="js/IndoorMap2d.js"></script>
<script src="js/IndoorMap3d.js"></script>
<link href="css/indoor3D.css" rel="stylesheet">
- three.min.js: 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)
- set up the parameters of the indoor map and pass it to the creator
var params={mapDiv:"indoor3d",dim:"3d"};
var indoorMap = IndoorMap(params);
optional parameters:
@mapDiv: if you have create your own <div> 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:
var indoorMap = IndoorMap();
- load the map data, and set up its styles.
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:
map.setTheme(myTheme);
map.showAllFloors();
map.showAreaNames(true);
map.setSelectable(true);
or in a chain for convenience:
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 <ul> tag with all the floor id. The user can switch the floor by clicking the <li>
You can insert the <ul> 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.

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.
