1.  What is the best way to present a GeoObj with text associated with it?  In 
looking @ the demoSetups, I add a MeshComponent to the GeoObj, but I dont see 
an example of how to also put a text description with it.

2.  How can I control how large the the VirtualCamera can "see" into the World 
object?  I am putting some GeoObjs in the World.  Some of these objects may be 
miles away from the current location of the phone, thus current Camera, so the 
user cannot see those objects. When I move the VirtualCamera(with 
EventManager.setPosition) close to the GeoObj, it appears, but I need a way to 
scale the camera so the user knows those items are in the world with out my 
moving the VirtualCamera close by.  

3.  Other frameworks(Mixar) have the concept of a RadarView that helps the user 
frame up the items.  And give some context to the GeoObjs in the World.  Any 
plans on implementing something like that to help the user navigate through the 
world object?

I hope someone can help us...we have a few project in the pipeline...and really 
want to use DroidAR...but the docs are kinda light.

Thanks

When loading a Texture in _b_addWorldsToRenderer 

localBitmap = BitmapFactory.decodeResource(myTargetActivity.getResources(), 
R.drawable.info8);

and using it with 

MeshComponent newTexturedSquare(String bitmapName, Bitmap bitmap,float size)

The Textures are displayed the first time it loads but after putting a new 
Activity on the Stack and returning to the Activity there is only a white 
square.

The Issue might be related to

-in-glsurfaceview/5247390#5247390 except for the Solution.

i am having problem in using 3d object loaded using libgdx project in droidar 
project to view a 3d object. please help me out,
thanks in advance.
Regards

I am using droidAR to show some GeoObjects.

Below is the code how i spawn the objects.


I am defining a mesh as MeshComponent mesh = GLFactory.getInstance()
                            .newTexturedSquare("mytext",
                                    IO.loadBitmapFromView(mylayout), 3);
                    mesh.addChild(new AnimationFaceToCamera(camera, 0.5f));
                    mesh.setScale(new Vec(10, 10, 10));

GeoObj x = new GeoObj(pos, mesh);
and world.add(x)


Can you please clarify these points.

1. I have spawned 5 pints . one at current location, second at 10m from current 
position , 3rd at 100 meters , 4th at 1 kn 
Now when i open the AR view, which of these point will be visible. ie where am 
i setting the radius for camera visibility 

2. I want to listen to location update and update AR view automatically . Is 
this possible and the default behaviour ? I saw the event handler for location 
update defined in the setup . WIll this take care of lo9cation update or should 
we override / implment any function.


Thanks a lot for your answers. It will be really helpful for me.

Simon-
In using droidar, we noticed that the altitude was not displaying right.  In 
looking at the code-
/*
             * The altitude should be set to a certain position too. This can be
             * done by using location.getAltitude() TODO first think of all
             * consequences!
             */
            final double altMet = 0;// location.getAltitude(); TODO
And-

    private void updateCamera(double latDistMet, double longDistMet,
            double altDistMet) {
        // myCamera.setNewPosition((float) latDistMet, (float) longDistMet,
        // (float) altDistMet);
        myCamera.setNewPosition((float) latDistMet, (float) longDistMet, 0);
    }

I see you are setting the altitude to zero(0) in purpose.

Any idea when this will get implemented?  Or am I just looking in the wrong 
spot?

Thanks

Hi!

I'm trying to use your engine (by the way, nice work), but I've founded may 
errors when I import your code due to the @Override tag, you are using JDK 1.5, 
aren't you? because if you use 1.6 the tag "@Override" produce many errors :(

I'm trying to display images at various GPS locations using GeoObj. The problem 
is that some images get thinned down, since they are along the axis. Because of 
this, it's hard to see them.
I also don't want images which are further away to be smaller.
Can you point me to where in your code do you rotate and resize the images so I 
can remove it, or is this just a feature of GL?

Also, I wanted to add text under the image to show how far away the object was, 
which should update as you move closer to the object. Any hints on how to do 
this?

Thanks a lot.

Hi, i've tried your new demo for loading external 3d objects using the tutorial 
video (multiple times actually) but it just won't work. It doesn't seem to want 
to load the texture and the 3d objects even with the unmodified example. i've 
tried modifying and setting different path types but with no success. Is this 
an issue or is it something wrong with my environment? If you need more details 
i'll provide them happily.

Color picking does not work on the HTC Hero eg. Check color order and adapt 
auto fixing method in ColorPicker

Has anyone done a TwitterFeed Setup?  And is willing to share an example?

We are looking to feed a world from a GeoLocated Twitter Feed.  Having the 
Lat/Long info, we want to display the feed in real time to a droidar world.  
Then letting the user click on the drawable, taking them to the actual tweet in 
the browser(or whatever intent).

What steps will reproduce the problem?
---------------------------------------
1. Install ModelLoaderAdapters from Eclipse
2. Select one of the models
3. The AR view starts - click the icon on top-left to cancel accuracy-detection 
- click on prompt to cancel accuracy-detection
4. Red screen with error log appears

What is the expected output? What do you see instead?
---------------------------------------
Expected to see the model (robot, head etc.) - instead I see a red-screen with 
an error

Following is part of the log from Eclipse:

Tried the same thing yesterday - but model would not load - only a grey circle 
shape would appear but the model and texture gave a "not found" error - today 
model-loading functionality itself crashed...

Hi,
my project contain the multimarker project and the modelLoaderAdapter, i can 
load the 3d obj, but i can't use them on the Marker project, i get null 
MeshComp all the time. what am i doing wrong?

I have downloaded the svn project and added to my app as a library . I am not 
able to see the documentation for the apis. How can i get the javadoc for the 
droidar project.

What steps will reproduce the problem?
1. Try to use DroidAr with Eclipse Indigo and 64-bit JDK.
2. Try to follow the youtube droidAr tutorial.
3. There is no way to 'Add SVN repository'

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
Windows 7, Eclipse Indigo 3.7.0, jdk 7 64-bit.

Please provide any additional information below.
I know it's not a DroidAR problem, but I'd like to know if it's possible to use 
with Eclipse Indigo, even if it's in 32 bit mode. Also, if JDK 64 bit is 
supported. 

If it's mandatory for DroidAR to use older version of Eclipse, it would save 
time to developers to know this in advance, same with JDK 64 bit.

Thanks in advance for the info. 
Best regards.

Hi all,

I currently testing the DroidAR lib, however I've got an issue with the camera 
aspect ratio:

When moving the phone I can see the aspect ratio changing and the video feed 
seems to be stretched. Is there anyway to lock the orientation maybe in order 
to avoid this behavior?

Thanks for the great work.

Hi all,

I'm currently trying to make some "droidar object" based on location of real 
object. Is it possible to make constant "droidar object" size? because when the 
distance of my object from become more far then my object become more small.


I try to read the code but may I'm little bit lost :s
I think there is a simply way to do this.

Thanks for your answer.

What steps will reproduce the problem?
1. Execute ANY program using droidar (even the test program on library)
2. only shows the buttons at bottom (if any)
3. Re Execute the program several times. 
4. it finally shows graphics. 

What is the expected output? What do you see instead?
I expected to see the graphics in the world but I only see the buttons at 
bottom (if any)

What version of the product are you using? On what operating system?
I compile the last source code, I'm running it in android 2.1-samsung galaxy 
S-not rooted

Please provide any additional information below.
*the problem is present even if I the objects aren't in movement (so it's not 
that I don't see them, its just they aren't)
*I think the problem may be because of lack of memory, but i'm not sure.
*The library app shows that my phone pass all test
*There is just one case where the app always works fine, it's the collecting 
items setup

pS: very good work, finnally some library that really understand what AR is all 
about

Hi, 
When i use the MultiMarker setup, when he recognize the Marker he put the obj 
on the Marker but when i remove the marker, the obj stays in the world. i tried 
to clear the world in the method onUnrecognizedMarkerDetected, but it didn't 
work. 
how can i do it?

Can I remove drawn MeshComponent when marker is not visible and then set it 
again? How can I do that?

Hello Sir,

I've loaded 3d object following your tutorial.. Can you please help me out in

Hi all,

I'm currently trying to add a screen-shot function to DroidAR. However I only 
have a black image.

I added my code in the onDrawFrame function but it's maybe not the right

I want to show route map based on AR from current location to a specific 
location.  Is this possible with droidAR . Is there any example illustrating 
similar requirement.

Thanks in advance for the support

Hi, I want to know where I can find DroidAR geolocation code so I can take a 
look and understand how it works. Besides, I'd like to know if this code can be 
overriden by a custom class or method. If so, how should I do it? Is it 
possible to toggle DroidAr's location on and off? How?

I'd also like to know if it's possible to override the default layout that 
DroidAR offers with a custom one.

Thanks in advance.

Hi,
I'm trying to put GeoObj on a specific GPS location, but only when the user is 
in this location and remove it when the user is no longer in this location.
the problem is that i get the object on the specific GPS location, but then he 
stays on the layout.
what can i do?

What steps will reproduce the problem?
1. Created an own Setup-Class which extends Setup
2. Using ArActivity with an instance of the custom Setup-Class
3. Starting the Application, going to the ArActivity, switching back to another 
activity.

What is the expected output? What do you see instead?
The location updates should be turned off and the GPS module should turn off as 
well.

What version of the product are you using? On what operating system?
Current version, Android 2.2.1

Please provide any additional information below.
I can't see a way to turn off the location updates by hand. The event manager 
should recognize when there isn't any listener left and should tell the 
LocationManager to turn off updates.

What steps will reproduce the problem?
1. follow tutorial on youtube "How to use the DroidAR framework in your own 
application"
2. app run fine but no solar system
3. note: my method addObjectTo has 'renderer' parameter like below
public void addObjectsTo(GLRenderer renderer, World world,
                            GLFactory objectFactory)
but on tutorial doesn't.

What is the expected output? What do you see instead?
get camera view but no solar system

What version of the product are you using? On what operating system?

What version of the product are you using? On what operating system?
latest Version (r304) Xubuntu 11.10

Please provide any additional information below.
I tried on 3 Different Phones:
Samsung Nexus S
Motorola Droid
Htc Wildfire
with the exact same Exception

How can i find out the xy-coordinates of the objects currently visible on the 
screen. I am drawing my own objects using DefaultARSetup and now i want the 
coordinates of those objects on my screen at any given moment.

Hi!
As the topic sais, i am trying to display raster data on a certain BoundingBox 
around the user position.
The raster data is a result of an interpolation with green-red color gradient.
The user should find himself "standing" on this raster data, hope you know what 
I mean...
With the newGrid method I was able to get this effect, by setting the camera 
perspective to Vec(0,0,1). 
But I see no way to fill the faces inside the Grid, cause they are just lines...
Unfortunately I am not able to get the Textured2dShape with my Bitmap to the 
same effect as the grid (lying on the floor).

Can you tell me how this could be possible?
Also if its possible to scale the Bitmap to certain BBox?

Thanks alot!

What steps will reproduce the problem?
1. creating a texturedsquare with a bitmap with the glfactory.
2. adding it to the world.

What is the expected output? What do you see instead?
A square. a triangle.

What version of the product are you using? On what operating system?
260 DroidAr, 243 ARMarker

Please provide any additional information below.
-

What steps will reproduce the problem?
1. moved from r230 to r252
2. I extend the FarAwayPOIScenarioSetup and call it, for instance, MyOwnSetup
3. then instantiate like this ArActivity.startWithSetup(MainMenu.this, new 
MyOwnSetup()); 

What is the expected output? What do you see instead?
launch of the ARActivity is expected, I get NPE instead:
java.lang.RuntimeException: Unable to start activity 
ComponentInfo{com.example.ctfar/system.ErrorHandler}: 
java.lang.NullPointerException

What version of the product are you using? On what operating system?
currently r253

Please provide any additional information below.

What steps will reproduce the problem?

What is the expected output? 
MeshComponent face the camera without animation

What do you see instead?
the MeshComponent face the camera with animation

What version of the product are you using? On what operating system?


Please provide any additional information below.
I just want to know how to make the MeshComponent to face camera without 
animation. (without AnimationFaceToCamera)

Hi!

I think that if you want to use the xml layout, you should add this constructor 
to the CustomGLSurfaceView class, if no it will not compile


public CustomGLSurfaceView(Context context, AttributeSet attrs) {
        super(context, attrs);
        if (DEBUG_OUTPUT_ENABLED) {
            // Turn on error-checking and logging
            setDebugFlags(DEBUG_CHECK_GL_ERROR | DEBUG_LOG_GL_CALLS);
        }
        this.setFocusableInTouchMode(true);
        myGestureDetector = new GestureDetector(context,
                new CustomGestureListener(this));
    }

What steps will reproduce the problem?
-----------------------------------------------------
1. Followed tutorial "How to use the DroidAR framework in your own application" 
here: http://www.youtube.com/watch?v=MFbEvkWJOV0&feature=related

What is the expected output? What do you see instead?
-----------------------------------------------------
The app loads successfully and shows me a button
Clicking the button should show a solar system - instead I just see the regular 
camera video output - and there is a graphic if I point the camera down - it's 
a thin angled line that is green on one end and red on the other end

What version of the product are you using? On what operating system?
-----------------------------------------------------

2. Used:
  a. Eclipse Indigo Service Release 1
  b. JDK jdk1.6.0_29 (32-bit) on Windows 7
  c. DroidAR, droidArDemo (test project) with "compiler compliance level = 6"
  d. Built against Google API 1.6

3. Running on Desire HD running Android 2.3.3

Please provide any additional information below.

Project is attached here - also I've seen this 
(http://code.google.com/p/droidar/issues/detail?id=9&can=1&q=not) - the solar 
system is not behind me

Hey !

I would like to implement some information view like you can see in AR 
application like wikitude where you see the far POI and a information display 
in 2D rectangle which is no affect by distance in real world (ie rectangle 
keeps his aspect).

You can see in this image.

I am not  comfortable with all opengl stuff so what i have done : (GLText is a 
bit simple for what I want to do)

- Make a FrameLayout add TextView in it.
- Use util.IO.loadBitmapFromView to get bitmap of FrameLayout
- Make a mesh with newTexturedSquare and the bitmap
- Then use this mesh

But I need to refresh the text.

What I will to do ?

- Delete mesh
- Remake a mesh with new text

But I don't know if it is optimal, I think not.

Do you have hints to do what I want to do ?

Actually I need to do farAwayObject effect but with the refresh of text.

Thank you.

When spawning an object , i wanted to show an image for the object along with a 
title. I tried calling spawnobject as below
Bitmap icon = 
BitmapFactory.decodeResource(getApplicationContext().getResources(),
                        R.drawable.myimage);
                spawnObj(poi, GLFactory.getInstance().newTexturedSquare("MYIcon",icon,5));

This will place the "icon" when object is spawned . But do not showany text . I 
expect "MYIcon" text also displayed along with the icon.

Can you please look in to this issue and please give a solution.

I am using real device with android version 2.3.5

What steps will reproduce the problem?
GLtext or GLFactory.getInstance().newTextObject not show the expected text 
perfectly. sometimes the text displayed only half.

Please provide any additional information below.
I suggest to combine the droidar with Android CBFG BFF Loader 
(http://www.codehead.co.uk/cbfg/ ---> OpenGL ES port of render code for 
Android: http://www.codehead.co.uk/blog/?cat=5)

thx

Hi,

First thank you for your work, it really nice framework.

I want to use DroidAR in portrait mode so I change the flag in manifest.xml but 
it changed only the gui overlay view. In portrait mode it's like camera is 
rotated by 90 counter clockwise . I try to read the code but I a bit lost :s

I think there is a simply way to do this.

Thank you for you answer.

I had some questions about the ARGo sample project. I wanted to create an app 
that combines two ideas from these to videos

http://youtu.be/brlNkKmw8IY
http://youtu.be/fEd0HORzStQ

I want to create an app that will allow arrows(instead of hexagons) to 
represent different locations. So when users click on the arrows, a simple 
alert dialog box will appear that will allow users to get more information 
about the location.

1)I was wondering if there is any sample source code of the ARGo.apk that I can 
look at to get an idea of how it works? Which setup do you recommend for this 
type of project?

2)If wanted to overlay a simple dialog box similar to the one in the ARGo 
example, should I use the DroidAR framework or should I use a surfaceview on 
top of a camera preview window?

Thanks

What steps will reproduce the problem?
1. following the video
2. running the app
3.

What is the expected output? What do you see instead?
should see a solar system as the video shows , I see two green and red lines 

What version of the product are you using? On what operating system?
windows 7 64bit

Please provide any additional information below.

What steps will reproduce the problem?
1. Trying to launch a new activity from a setup by pressing on an object 


What is the expected output? What do you see instead?

I want to launch a new activity from a setup by clicking on an object. I've 
created a new Command and within the execute tried to launch a startActivity 
but I allways have a null pointer exception error when trying to launch an 
intent with startActivity. I've extended the Setup class with Activity so I 
could be able to do that, any sugestions on how to do that? 

What version of the product are you using? On what operating system?
Latest version on Windows 7.

Please provide any additional information below.

I know this isn't really an issue, but I've been trying to achieve this for 
some time without any success, if you could help me I'd be most appreciated!

What steps will reproduce the problem?
I implemented the "_e1_addElementsToOverlay" method in my own setup class, and 
I want to draw a rectangle on the screen in my view instance. 

Here is the code:
public void _e1_addElementsToOverlay( FrameLayout overlayView, Activity 
activity ) {

        overlayView.addView( new FrontSightView( activity ) );
        super._e1_addElementsToOverlay( overlayView, activity );
    }

The FrontSightView works fine in a normal Android activity. However, it does 
nothing in the ar case. Do you have any clue?
Thanks a million!

What steps will reproduce the problem?

1. Checkout of Droidar Project like told in tutorial video
2. Clean Project like told in video
3. Build Project


What is the expected output? What do you see instead?
I expected, that the project would be build normally after cleaning it like in 
the tutorial video, but it doesn't. Instead I'm getting about 256 error items, 
which seems all to have a problem with the @override annotation. I can't use 
droidar as a library, if the droidar project can't be built.

For example: 
Description Resource    Path    Location    Type
The method getView(Context) of type DoubleModifier must override a superclass 
method  DoubleModifier.java /DroidAR/src/gui/simpleUI/modifiers line 24 Java 
Problem


What version of the product are you using? On what operating system?

Latest Revision of DroidAR (167) out of the trunk folder. Eclipse Indigo and 
latest android-sdk. Windows Vista 32 bit.
