i tested User Defined Targets of Vuforia Samples application. Everything is working fine but i have one question. There are some values in translation vector of pose matrix when UDT is created and phone is still in the same position. Can someone explain to me why it is happening?.
Example HTC Desire (Android 4.4.4)
UDT sceneSizeWidth: 320.0f
Obtained by calling trackableResult.getPose().getData()
(0.9999998, -5.213349E-4, 4.02942E-4, -0.33349234,
-5.192455E-4, -0.9999865, -0.005168112, -0.3648581,
4.0563088E-4, 0.005167902, -0.99998665, 270.65475)
Phone was still in the same position but there is a x,y translation.
It is potential blocker for my own application because i need to render 2D shapes above UDT in really accurate way from real middle point of UDT.
Thanks in advance.
