Trackable width

By AparGames on Wed, 06/20/2012 - 17:09
Hi, I am confused with the width parameter which we have to input while making a new trackable object. Is it in relation to the actual dimension of the image? Or is there a way to find out what should be the width parameter? Also, what is to be done in order to increase the size of the object ( cube in the simple example project documentation ) Thanks

That width defines the size of the trackable in scene units. It's somewhat arbitrary, but needs to work with the near and far parameters you use for the projection matrix.
