i am attempting to use Vuforia for AR market detection and 3rd party rendering engine libgdx for rendering.
however i am not able to use the modelview matrix provided by vuforia correctly,
There is a 90 co-ordinate axes rotation between the vuforia and libgdx system which i have encorporate
i have update the camera fov in the libgdx based on vuforia calibration API's
i amd extracting the camera pose from inverse,transposed modelview matrix and setting camera pose in libgdx
i amd extracting the object pose from modelview matrix and setting object pose in libgdx
below is the link to the code which i am using
i have referred to code of integration of vuforia with other 3rd party engine like gamekit and rawali and they also follow a similar procedure
and also post in vuforia knowledge center and forums
i am unable to debug exactly what is it that i am doing incorrectly.
