Custom UX

Smplr.js provides a few options that help you customize the map experience to your requirements. We're regularly adding new options, so reach out and share what you'd like to do with it.

Adapting the look & feel and experience

Render options

To customize how the map viewer renders the spaces, you can pass in a number of options to the rendering engine. Below are the options currently exposed. Render options can be updated dynamically as described further.

interface MapSpaceRenderOptions {
  footprint?: {
    render?: boolean
    color?: string
  }
  walls?: {
    render?: boolean
  }
  grounds?: {
    render?: boolean
  }
  windows?: {
    render?: boolean
  }
}

Viewer controls

Update render options dynamically

Render options are described in details in Render options. You can update them dynamically with the method below:

map.updateRenderOptions(options: MapSpaceRenderOptions) => void

• options is an object of the MapSpaceRenderOptions interface, which is deeply merged with the current options used by the viewer. To "unset" an optional value, you can pass undefined explicitely.

Navigate levels

To programmatically choose which levels are visible on the map, you may use the following functions:

map.showUpToLevel(levelIndex: number) => void

• levelIndex - zero-based index of the top level you want to see. For example, setting levelIndex to 2 is equivalent to pressing the L3 button in the space viewer.

You can also reset the viewer back to showing all the levels with:

map.showAllLevels() => void

Camera controls

Get the camera placement

map.setCameraPlacement lets you position the camera. You would typically embed the map viewer and have an interface to retrieve one or more placement(s) to be stored in your database. You can then load any placement object from your database to set the initial value. The camera placement can be retrieved with the following function:

map.getCameraPlacement() => ({
  pitch: number
  bearing: number
  zoom: number
  center: {
    lng: number
    lat: number
  }
})

The "placement" is a Javascript object that includes the position and direction of the camera. It is defined as an orbit position (pitch, bearing, zoom) around a center point which the camera points towards. It is fully compatible with the native Mapbox camera values.

• pitch is the angle given in degrees of the camera's position in the vertical plane. 0 corresponds to a top down view, while 90 corresponds to a view from the ground.
• bearing is the angle given in degrees of the camera's position in the horizontal plane. 0 faces North, 90 faces East, and -90 or 270 faces West.
• zoom represents the distance to the center point. It has a value between 0 and 22, with 0 showing the whole Earth, and 15 showing buildings.
• center contains the GPS coordinates of the center point in { lat, lng } format.

Set the camera placement

You can move the camera to a specific position and have it target a specific point as well by calling the following function:

map.setCameraPlacement({
  pitch?: number,
  bearing?: number,
  zoom?: number,
  center?: {
    lng: number
    lat: number
  },
  animate?: boolean,
  speed?: number
}) => void

• placement parameters (see description above) are the new desired value. All parameters are optional and the ones that are not provided will keep their current value.
• animate - optional - should be set to false to jump to the new placement and true to animate the camera to the new placement. Default value: false
• speed - optional - defines the speed of the camera animation and should be used with animate set to true. Default value: 1.2
