Hi Lukasz,

I would like to know how to change the image tracker to use any of the Frame Markers, and what implications have commenting the - (id) initWithFrame:(CGRect)frame method if I want to create different new iOS projects.

Many thanks!

I try to switch an interface from OF_ORIENTATION_90_RIGHT to OF_ORIENTATION_90_LEFT when the phone is rotated during runtime. How can I tell the add-on to accept the new landscape orientation during runtime?

Have you ever tried to make the vuforia framework work on android with open frameworks as well?
I was wondering how difficult it would be to use open framework to develop some vuforia application for ios and android at the same time?

The retina display from the iPhone 6+ has a scale of 3.

ofxQCAR.mm line 216 needs to be changed to:

  ARViewBoundsSize.width *= [UIScreen mainScreen].scale;
    ARViewBoundsSize.height *= [UIScreen mainScreen].scale;

Since the scale for non retina displays is 1 the if can be removed.

Hi julapy!

I seems like it isn't possible to color strings (the color is always white):

[code]
ofSetColor(245, 58, 135);
verdana.drawString("Test string", 145, 92);
[/code]

Am I the only one experiencing this?

Kind regards,

Is there some why to synchronize with a new video frame?

I am running an app with 60 fps but I assume the video only runs on 30fps.
This means that for every other frame the image gets drawn double.

I would like to perform something on the frame where new video content is loaded and do other things on the frame when the video content is just redrawn.

Hi,

You have closed the issue, so the only way I can reply is by creating a new issue. :)

I have still the same problem. I am using open frameworks 0071, not 007. I have also rebuilt all the libraries. The problem persists.

All the best,

I wonder if is possible to detect 2 or more markers, i'm trying creating 2 instances of ofxQACR like:
ofxQCAR *qcarA;
ofxQCAR *qcarB;

qcarA = ofxQCAR::getInstance();
qcarA->setup();

qcarB = ofxQCAR::getInstance();
qcarB->setup();

and so on but no luck...

Hi julapy,

I am testing the current and the developer QCAR. I get the following errors in both cases: "Preprocessor issue: ofxiOSEAGLView.h not found" and "Semantic issue: No member named isRetinaEnabled in ofAppiPhoneWindow".

I am testing this with openframeworks 0071, iOS 5.1, and Xcode 4.3.3 on Mac OSX 10.7.5.

Kind regards,
smornish

pause feels more like a still image instead of stoping the entire camera and then need to reinitialize.

How do you think about adding a stop to the API that will deinitalize the camera as it is right now and the pause is only stoping the camera from feeding new frames?
That is basically the pause right now but without the deinit code.

QCAR 1.5.8 update request
since the library is updated
could it be possible to do the update for better performance
thanks

Hi,

I have been experiencing problem while displaying 2D elements on the marker tracked, using the GL_PROJECTION and GL_MODELVIEW matrix.

In ofxQCAR_Utils.mm, in the function (void)startCamera:

// Cache the projection matrix:
const QCAR::CameraCalibration& cameraCalibration = QCAR::CameraDevice::getInstance().getCameraCalibration();
        projectionMatrix = QCAR::Tool::getProjectionGL(cameraCalibration, 2.0f, 2500.0f);

The far boundary (2500.0f) of the GL_PROJECTION matrix is maybe set too low? With this value on an iPhone, the displayed image is being culled approximately at 20 cm from the image.

Is it possible to change this value with some function or during the initialization of the addon?
