I need to implement location based app with augmented reality. I draw a model with simple interaction with it (that's why I've chosen LibGDX) and I need to place this model on some point at the real world.
My small research gave me some solutions (like this or this). But all of them use marker-based drawing, but I need to draw model on surface.
Could anyone help me?
Person from Google has made some effort with ARCore using Libgdx, and had created a blog:
Investigating ARCore with LibGDX
Take a look at BaseARCoreActivity, which we can use to show some 3D Modle defined in Libgdx.

I am a complete beginner with ARCore and I would like to ask if it is possible to display 3D objects using 3D coordinates and having the user as the origin? For example, having (x,y,z) values of (0,3,0) will display the 3D object to the right of the user.
First of all: There is no native implementation in ARCore for that!.
But you're not completely lost. There are some very useful libraries in Android like appoly. I've used this fork from Eric Neidhardt.
For iOS I only know this library based on ARKit.
You can also make a Unity3D app in C# and use AR Foundation and Vuforia Plug-in. This way is platform-independent, but imho testing is a pain.
You see, there are a few options out there, but be careful that none is really accurate!
I want to create an app similar to quiver for Android. That is i need to recognize the sketch from a color book and place a 3d model with simple animation on top of it. I was planing to use ARCore but most of the tutorials use scenefoam which is now deprecated and saw some suggestions that I should use Filament directly. I would like to be pointed to resources and tutorials that i need to go over in order to be able implement the basic features of the app (recognize a 2d image and place a 3d animated model on it without using scenefoam).
i want to make an augmented reality which the building as a marker. in my research there is object as a marker for an augmented reality, i didnt found that object is a building.
. I want to know that is this possible that i can use real object (building) as a marker in augmented reality, If yes then would you suggest me that which any sdk for which will help me to build this in iPhone and android like Vuforia.
how to make a building as marker? what app that use for that ?
please help me. thank you
Vuforia is perfect for this my friend. It's completely up to you on which SDK you chose but I use vuforia so I woul suggest that. There is no app for specifically making buildings markers, instead they are methods to make it possible. These are just my views on how this can be achieved and as far as my knowledge goes, it should definitely work. There are two ways of doing this:-
Using the Vuforia Object Scanner: This is a slightly expensive approach. Since buildings cannot be directly placed under the camera for this app to function, you could get the builduings achitectural drawings and 3D Print a miniature version of it, so that it is now easier to scan.
Using MultiTarget: Well, this is basically very straightforward, the picture of the builing (that is the Front View, Side View and Plan) are uploaded into the Vuforia Target Manager and can be made into a Multitarget object and this can then be used for various applications.
I'm asked to do an app with a 3D object mapped on a tag on the camera preview. The user should be able to rotate the 3D object on swipes, and to click on different area of the 3D object.
I'm investigating the different way to do it.
So far the best option I've found seems to be https://developer.vuforia.com/resources/sdk/unity, but I can't find whether it's possible to interact with the 3d model (rotate on swipe, define clickable areas).
Has anyone any experience with that?
I guess I can do it with some OpenGL, but I have no experience with it and it seems quite complex to start off with.
Is there any other library I should consider?
I would use OpenGL and start by the training tutorials on http://developer.android.com/training/graphics/opengl/index.html. Hope this helps! If you follow these tutorials you will be able to do what you want. ive tried unity and it is a really good engine too. and of course you can make an object clickable with unity! maybe using unity would be easier but the documentation on opengl is huge and is not that difficult to implement at least with first steps. hope this helps
The Metaio SDK can do all of that but I am not sure if it automatically provides the area of the model tapped, but you could ask here.
I'm looking for a 'basic' AR SDK that allows me to draw images and 3D shapes around the user (no matter where he is). It would be even better if the SDK includes a simple way to detect interaction with the shapes (something like onClick).
I made a project from scratch on Android but there's still a lot of work to do and I'll need to do the same on iOS after... So that's why I'm looking for an SDK or a similar project (no matter what platform).
I tested Metaio but it's quite expensive and maybe overkill for my purpose because it uses LLA coordinates.
I tested DroidAR on Android but it's only for Android and it looks heavy too (don't need the GPS).
How about Qualcomm's Vuforia? I was able to quickly get a sample project running on it.
EDIT Looks like I was wrong about what it could do. According to this (which is slightly dated, so who knows) Metaio might be your only choice.
i really don't sure what you really want to do ..but if you simply show images or 3d models on camera without any detection you can achieve this very easily i am explaining for Android and you can extend it to ios on same logic.
first approach:
you have to use custom camera of Android in your app,then use any game engine as per your need..i will suggest Jpct-ae or Rajawali
they are very simple to integrate and can be used for 2d images and 3d models.
this tutorial will explains a lot
keep the gl-surafce transparent and you can have model floating in space ...
second approach :
to add some more effect to your AR app you can use sensor values to move model in 3d space as per movement of device..it gives a cool effect.
use first approach and additionally collect sensor values and apply that matrix to gl camera of your game engine..for sensor values follow here
good tutorial here..
i hope this may help you..i done these a long time ago but try to help if you want..
