Pretty fast, since it can perform at 60FPS easily.Compatible with all the browsers and all the devices.This means that you can do with it whatever you want (even commercial applications) Completely opensource, with MIT license.

(It’s interesting to notice that the proposed solution can also be adapted to other frameworks, but I discovered it with AR.js, so I will show you how to develop it with AR.js) What is AR.js?ĪR.js is a Javascript framework that lets you offer augmented reality through your browser, created by Jerome Etienne and ma intained by Nicolò Carpignoli. How to solve this problem? Well, a guy named Nicolò Carpignoli has proposed a very smart solution that employs AR.js to create a completely seamless AR experience, and experience you will have time for 😉 WebXR removes some friction from the above process (the part where the app has to be installed)… but anyway leaves a lot of work to be done: the viewer has still to open his/her browser, write down the link, frame your business card and then finally he/she can enjoy your animation.

Thanks to this technology, it is possible to enjoy augmented reality without the need to install any kind of applications on your phone.Īs a developer, you have to create a webpage using the various frameworks through which you can offer augmented reality ( A-frame, the 8th Wall, ARCore, AR.js, etc…), then just provide a link to the person that you want to experience AR and bam, he/she can try your AR experience just through his/her browser without having to install anything! If only there were a way to try AR without installing an app… WebXR to the rescueĪctually, there is a way and it is called WebXR. The process was cumbersome, and also left an app on your phone… an app that was just useful to see a cube pop up from my business card… pretty nonsense, wasn’t it?

The problem of this kind of showcase apps (apart from being useless) is friction: in my case, you had to download an app from the store, open it, frame my business card with the camera of your phone, just to see a cube with my face popping out! Yeah, all the process was pretty annoying You had to download my app, then you could point your phone at my business card and see a textured cube popping out of it! Amazing, isn’t it? (Image by QuickMeme) I did one myself some years ago, even using Metaio, a framework that 4-5 years ago disappeared because it has been acquired by Apple.

One of the classical showcase augmented reality apps are AR business cards.

If you don't care about the map zooming in and just want the marker to be at the bottom see below, I think it's a simpler solution double center = mMap.getCameraPosition().target.latitude ĭouble southMap = mMap.getProjection().getVisibleRegion(). ĭouble newLat = marker.getPosition().latitude + diff ĬameraUpdate centerCam = CameraUpdateFactory.newLatLng(new LatLng(newLat, marker.getPosition().Mobile augmented reality has many problems that are hindering its success and one of them is the necessity to download applications to enjoy it. MMap.animateCamera( CameraUpdateFactory.newLatLngZoom( centerlatlng, 15 ), 1000, null) LatLng centerlatlng = new LatLng( latlng.latitude + degree_30p, latlng.longitude ) zoom_lvl = mMap.getCameraPosition().zoom ĭouble dpPerdegree = 256.0*Math.pow(2, zoom_lvl)/170.0 ĭouble screen_height = (double) mapContainer.getHeight() ĭouble screen_height_30p = 30.0*screen_height/100.0 ĭouble degree_30p = screen_height_30p/dpPerdegree

So, calculation based on google map spec will definitely solve the problem.īelow is an example code of moving the marker to 30% of the screen size from bottom. mProjection.toScreenLocation()), my guess is the projection resolution will go poor when the map zoom level is low, it made me sometimes couldn't get an accurate position. I prefer Larry McKenzie's answer which it doesn't depend on screen projection (i.e. GoogleMap.animateCamera(CameraUpdateFactory.newLatLng(targetPosition), 1000, null) LatLng targetPosition = omScreenLocation(targetPoint) Point targetPoint = new Point(markerPoint.x, markerPoint.y - view.getHeight() / 2)

Point markerPoint = projection.toScreenLocation(markerPosition)

LatLng markerPosition = marker.getPosition() Projection projection = googleMap.getProjection() view is a View object containing the inflated map Look here for my answer on how to get the map's height.
