im working on an AR application now, which should be able to detect a horizon and play a video with transparency behind or on top of the horizon.
What I did yet: When I add an image to the target manager, I do not want to have features everywhere on the image so I added white plains to everything that should not be tracked (see image1 and image2). I only want to track get the horizon tracked (not perfect in that example tho, just wanted to show the concept I used here).
What I want to achieve is: interact with the horizon. So, when I got an image tracked and my video playback is under/behind the horizon the horizon, the parts of the video which are behind the horizon should not be shown. Watch here to see what is my goal: https://youtu.be/rvrZJ5C_Nwg?t=2m20s .
Is there any way to achieve that? When I started with Vuforia I thought I could maybe get reference to the features, but I don't think thats possible ?
