Hi,

Back to the marker/tracking question:

I know it's probably OK to render the virutal object in another location rather than stick it on the marker (i.e. apply some tranformations). However, if the marker is used as a tracking reference, i mean for matching the 2D projection of the marker and the virutal object, how do you then work out the projection angle of the virtual object when it is placed at another location?

For example, if we place the marker on the wall, how do you make the virtual object stand vertically on the table rather then sticking horizontally on the marker on the wall? Of course, this is a simple case because of they are roughly right-angled, we will appreciate a more general approach.

We will definitely wriite Vizard into our budget plan if this can be solved.

Many thanks!
