We have an area (in x-z plane) of approximately 2metres x 5 metres.
We would like to place a physical camera in this area and to move it around the area (remaining in this plane).
We would like to render a virtual object of approximately the same dimensions as this volume occupying this space and show the virtual object from the real-world camera viewpoint.
(So, something like what one would get from head-tracking around virtual object)
Is this possible to do with a single marker or multi-markers?
Would we need a very large or very small marker?
