Marking Up a World: Physical Markup for Virtual Content Creation


FXPAL’s Pantheia system enables users to create virtual models by ‘marking up’ a physical scene with pre-printed visual markers and then taking pictures. The meanings associated with the markers come from a markup language that enables users to specify geometric, appearance, or interactive aspects of the model that are then used by the system to construct the model.  Our “Marking up the World” video appeared at ACM Multimedia this week. In the video you can see how our system works, our viewer features, and a selection of the spaces and objects we have used the system to reconstruct.

Thanks much to Qiong Liu for presenting it, and to John Doherty for putting it together from our clips and for narrating it. The geometric reconstruction work I spoke about last week as part of the Bay Area Mathematical Adventures series was inspired by the issues we discovered while building the system. For more details on our work, see the paper we presented at CGVR ’09 Interactive Models from Images of a Static Scene.
