Hi,

I'm trying to use the AR-toolkit within an MFC application.
So far, what I have been able to do is to initialise the camera, load the patterns description, grab the camera, display it in an MFC window (just for control because I don't really need it). 
But then when I try to detect the markers, the answer is always: no pattern !

Here is approx. the sequence of AR function I'm calling:

CoInitialize
arParamLoad
arParamChangeSize
arInitCparam
arParamDisp
argInitWithoutGlut // which is exactly argInit() -from gsub.c- without 
                   // the last call ArgInit2() that initialises GLUT 
camera.Init(0,m_xsize,m_ysize);
camera.DisplayProperties();
camera.SetFlippedImage(true);
        
In the main loop:

GrabFrame
GetBuffer

wglMakeCurrent // select the correct drawing area in my application
argDrawMode2D
argDispImage

arDetectMarker(dataPtr, thresh, &marker_info, &marker_num)

and marker_num is always = 0 !!!

When running Simple.exe in exactly the same settings (same camera param file, same object_data file, same pattern description files, same lighting conditions) ... patterns are correctly detected !!


Any idea where I could have a look to try to solve that out ?


Thanks in advance.
E.D.
