I want to place an object (2D or 3D) on the ground. So how can I
- measure the current camera position (based on the sensor)
- get the real-world y compared to the current ground
- get the angle / current camera position and pose
- calculate all of the gathered data into something that I can use in libgdx for rendering the object correctly over the camera preview ?
What I am going to achieve: When walking through the streets, I want to see augmented objects lying there or some textual information.
